? Thanks Larry! I really appreciate it. Our domestic and International clients seem to grow every day. Vintage HI-Fi restoration also seems to be hot. Pete, wa2cwa www.manualman.com On Sat, 8 Feb 2025 23:57:51 +0000 (UTC) "Larry Knapp via groups.io" <kc8jx@...> writes:

? Thanks Pete. I appreciate the complement. I find it very gratifying that my work helps someone bring a piece of equipment back to life. It also provides me with the joyful option of bringing a possibly bug invested, stored in a garage or basement for 50 of 60 years into a worthwhile and useful document that others can read, use and enjoy. Of course, one can find poorly scanned, incomplete, and highly marked up pages all over the Internet, but even when printed, crap is crap, and stuff is always lost in the transition. I just finished a military manual for a customer. Roughly 200 pages but easy to do even though every page, because of age, was brown. My machine can remove background paper color. But the hicker and hard part, were the five schematics. They were 14 inches high and 52 inches wide. And I decided these were to be done full size. A customer never has to assemble and tape any of my manual pages. This entire project started back in the mid 90's as a bonding project between father and son. Son was in his second high school year but didn't seem to have any idea about his future life endeavors. Since I was dragging boatanchors home to repair and get up and running, from every hamfest I went to, my collection of manuals for this stuff started to become a pain to manage. My son created database to manage all the manuals that I also kept collecting. He also suggested creating a catalog booklet, advertising in Electric Radio and a few other publications, and send out the catalog to all interested parties. I firmly believe this gave him a sense of business activities and helped firm up (or at least give direction) to his future. He also created my first web site and credit him for giving it its name. http://web.archive.org/web/20000621065933/http://www.manualman.com/ After high school he worked for a year before applying and being accepted at Boston Bible College at Hyde Park, MA. He felt he should earn the money to pay for college rather then taking it for granted. For 3 summers while in his college years, he worked at Lucent Technologies as a contractor and used the money earned for tuition. My apologies to the group for rambling, but I'm very proud of my son. I gave him a license manual when he was around seven. When he turned around 27, he finally found the time to become KB1JTP.

With thanks to all our Hallicrafters Experts on this site and they are experts for sure. Its been educational. Regards, and have fun. K2WH Bill's QRZ Biography

I have had several people contact me recently about a missing page in the online SR-2000 Operation and Service manual. Page 32 is missing from a most of online manuals. Very important, shows important alignment information. For the record I have found only one source that provides a complete manual. jptronics.org halli.sr-2000.pdf Walt Cates, WD0GOF https://wd0gof.com/Hallicrafters A majority of acceptance is not proof of correctness. https://wd0gof.com/bible-study/commentaries/

I had a glitch on my website today. 10 people downloaded the SR-2000 repair manual and got the old version. If you your download does not have "ver 8.51" on the front cover, try again. The glitch has been fixed. Sorry for any inconvenience.

All: I have read the very good explanation of the different revisions to the SX-117. Mine is a post-B model, which means that the notch filter doesn't affect the AGC response. I am inclined to revert that part of the build back to Rev B so the notch filter behaves "correctly", but before I look at this I'd like your opinions on the wisdom of doing this. What do you folks think? Thanks, Dave Maples

I just recieved a SX-117 thatI plan to restore and put in service. It's serial number doesn't seem to match up with Walt's run list. I'm assuming that the first 6 digits are the serial number and the last are a sequence number Or is it the other way around? Help! Thanks, 73 Jack KZ5A

I am approaching the last task in my S-85 refurbish project: Alignment. For those IF cans I cannot find the right tool mechanically match those cores' slot: it is too long and too large. I own these tools, none of them fitting: I see two alternatives: 1) buy one (can someone provide me directions on where to buy and exactly what?), or 2) build one (preferable - can someone provide me the slot size specs?). Thank you very much guys. Emanuele.

I now own an SX-42 I seem to be getting quite a collection here...... SX-9, S-19R, S-38C, 5R10, SX-100, SX-43 . Anyway, everything is working, BUT the FM is "funky". Aside from it being quite drifty, it also tunes station in strangely. I understand "capture effect" on FM, but it seems like there is very little tuning range between stations. I was using a little digital FM modulator today to place cd's and the radio was "all over the place". Any ideas? AM broadcast and shortwave are both fine :) Howard

This is a real long shot. I need a T3 for the HT46, part# 050-002146. It is the 15-meter transformer. AND DO YOU WANT TO HAVE FUN. I got the transformer out. I did it with a long break between each of the 4 terminals to reduce the stress. It is directly over the band switch and you do not have a straight at any of the 4 terminals.

I am in the process of recapping a S-38 that was given to me. I have not powered it up. It still has all the paper capacitors and non polarized AC Plug. It has 6 tubes and a BFO. It does not have the C-38 and C-39 silver micas that, according to my schematic, were added to later models of S-38. I have found an extra 0.2 @200 V paper capacitor connected between Pin 6 of 12SK7 tube and ground. Its condition is similar to all the other paper capacitors that I am replacing. As far as the physical location, one lead is connected to the same ground lug that C-36 uses. Should I replace it or not? I would greatly appreciate any insights and suggestions, as my experience with vintage radios is minimal 73, Barry W4LSV

Hello. I am in need of a mechanical part for my SX-62B. The dial pointer travels on it and the whole unit moves side to side to allow for the dial pointer reset. Mine is pictured below and as you can see the pulley on the left is missing. I am looking to buy the complete unit. I will buy a junker if need be to avoid turning my current SX-62B into one. Thanks for reading, Markus.

I generously received a 117 v Dow relay to connect my HT-44 and SX-117. I’m now wondering if the relay contacts in the HT-44 (pins 2-3) control outlet connector are up to switching the 117 V to the Dow relay. Or should I look further for a 12 V Dow? Figure5 in the HT-44 manual shows the use of a 117 V relay. Any concerns or am I overly concerned? Thanks. Skip Magnuson W7WGM

Hello all, I am rebuilding a Hallicrafters SX-122. Two of the three ballast resisters are broken. Where do I find replacemets?

I have two of these. Receiver #1: in poor condition, some missing electrical components and connectors. Enclosure is poor, with a meter hole cut into the front panel, additional non-original front panel holes. All controls are present and while a few are stiff, none are seized. Both main and bandspread dials function. Non-original hardware. Someone has worked on this one before and left a bit of a mess. This is a parts unit. Receiver #2: in better condition than #1, but still not great. Appears to be mostly complete (no guarantee on completeness), with some obvious work having been done previously (a replaced transformer, some replaced electrolytic can caps, an added Jones connector on rear, maybe more). Enclosure is complete with no extra holes in front panel. Non-original enclosure hardware. All controls are present and while a few are stiff, none are seized. Both main and bandspread dials function. This is a parts unit or, while it would take some work, is a possible restoration candidate. If it isn’t clear from the above, neither receiver is operational. No testing has been done on either receiver or on any of the components. No tubes are included with either receiver. I acquired these as part of a collection of other things I was interested in, and thought I might get to them someday. I will not get to them anytime soon, and I need to shrink the hoard, so off they go to someone who might, maybe, be able to make most of a good one from the two, otherwise both should useful as parts sources to restore other S/SX-15’s. Receiver #1 asking $30. Receiver #2 asking $55. Take both for $75. I also have a pretty good spare Sky Challenger silver dial; someone had lightly marked it on the back with "SX-18?", but it appears to be the same dial with same markings as on the S-/SX-15 receivers. Finally, I have a spare one of the small Hallicrafters nameplates (with the 4 little screws). Pardon the photo quality, the dial is actually nicer than it appears due to the crappy lighting I have. Offers considered on these, or we can negotiate inclusion with the receivers. Cash only, payment upon pickup at my location in York, PA, or at delivery at a local (to me) meet-up, or at delivery at an area hamfest if we are planning to attend anyway (we usually attend many hamfests within an hour or so of York, PA, and others like Berryville, and we're going to the Xenia OH "Dayton" hamfest this year). I will not ship the receivers. I will consider shipping the spare dial and nameplate if they are purchased separately, shipping cost to be paid by buyer. Inquire for more information, additional photos.

I need a meter for a hallicrafters ht46 transmitter. It was damaged in the process of being shipped. Please, can any one help?? message here or direct to rholstiaticlouddotcom replace at with @ and dot with . (period) Robert KH2BR

Looking for a Hallicrafters SX-146; working or not, lone or buy. Walt Cates, WD0GOF https://wd0gof.com/Hallicrafters A majority of acceptance is not proof of correctness. https://wd0gof.com/bible-study/commentaries/

No, I read it correctly. You are proposing a distinction without a difference. The Edison system was developed to reduce the number of conductors and the cost in a power distribution system, a benefit applied equally well to both DC and AC systems. Might as well debunk another myth that AC is more efficient then DC in power distribution. The main losses in both systems is due to wire resistance but AC distribution also has reactive and skin effect losses that DC distribution does not have. AC power distribution is perhaps more convenient but it is less efficient. See: https://www.cencepower.com/blog-posts/line-losses-power-transmission-3-types Regards from a snowy Arkansas, Jim Logic: Method used to arrive at the wrong conclusion, with confidence.

A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system. Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended single-phase system.[1]

I have just been approved as a member of this list and have been busy reading many of the posts to familiarize myself with it. I am not a licensed amateur radio operator but have been a SWL since high school in the Sixties. I "discovered" shortwave when my father let me fiddle with his 1936 RCA Victor 2-band consumer radio which he had purchased new. I found it in my parents' attic ca. 1990 and restored it. I own two Hallicrafters receivers--an almost-functioning S20R which I've owned for a couple of years, and an SX-28 (not an "A" model) which I've owned and used for over 30 years and which failed a couple of months ago. I intend to get both operating before long and will probably have a few questions about them for this list along the way. Looking forward to following many of the topics discussed here. Tom
