My ft101b functioned for about 5 minutes when I first bought it. On my first attempt to transmit with it the PA system gave up the ghost almost immediately. Turned out the rectifier board had several

Dan, I'm not sure what it will need when I'm finished with the recap.? So far when I test, I'm hearing stations where they are spotted, and when I call CQ I'm spotted on frequency.? I haven't taken

Pat, I checked on eBay where I bought my recap kit for the FT-101E, but it doesn't show the reference designators.? The E version doesn't have C142, C143 otherwise I would open mind up and see.?

Tom, not sure my answer posted.? I found T12 on the schematic. I can't find any documentation showing that T12 is supposed to have an electrolytic cap? between its leads.? Wondering if your T-12

My version of the service manual lists T12 on the main board ( http://www.manualslib.com/. Highly recommended.) . It is an AF choke, 20mH, 0.5 A. I have not found it on the schematic, but have not

Dan, thank you for searching.? The caps are 1uF and 100uF.? I also have replacements for the C78 and C77 caps in your picture but that is a separate project. I did buy a kit and there were extra

Tom, thanks for looking. I'm about ready to chalk it up to an undocumented change.? I found another anomaly while working on the chassis.? There is a large transfomer on the bottom of the unit that

Hi Pat, I checked the service manual and schematic for C142, C143 but could not locate these parts.? Can you provide that schematic.? If you already have the two capacitors, do they look like this

Looked this morning on 2 different documents for your caps and could not find them either. I feel your pain.?? Just now I'm trying to resurrect a 101B purchased in working order (hah!).? I

Hello, I have been replacing the electrolytic capacitors in my radio, and have gotten down to C142 and C143 listed on the parts list as being on the main chassis.? I can't find them either on the

Erwin, Thank you so much for the schematic for the PB-1827 LED version. I have one of these LED receivers as well as several of the more common VFD versions and have never been able to find any

GOT IT! I found a "Yaesu FR-101 Digital Counter Unit instruction manual" with discription and partlist of the VFD tubes version BUT with a schematic of the PB-1827 LED version. I uploaded it to the

Hello again to the Group. I have swapped out the PB-1534 from the working unit to my faulty one which had no SSB Tx?and have resolved the "No-SSB" problem.?So if ever you have no SSB drive (or SSB

Hello to the Group. Any help would be greatly appreciated. I have a friend's 2 FT-101E's here and both had essentially the same operational problems, that is both worked well on all modes, Rx & Tx on

Thanks for your reply, Emerson.? I have the board out and am currently removing and testing components.? Surprisingly the badly charred resistors test right on the money.? Some of the smaller

Tom It is possible to remove it. It's not easy but I did that. Probably it is necessary to verify all components. take a picture and note the position of all the wires You can loosen the screws on

All- I bought a cheap Yaesu ft101b to learn about tube HF.? Based on guidance from this board I started it on a dim bulb tester (receive worked), tuned it per manual and service manual (they do not

I replaced the Q3 2SC784, and the B-C-E voltages test good now, so we’re making progress. However still no TX output. After tuning against dummy load, and then connecting to MFJ-904 tuner and

Emerson, Thank you for sharing that BF199 interchange information. I’ll definitely make note of that for future reference. I was able to locate a pair of new original Toshiba 2SC784 that just
