In the clip of an ad in your last message. At the bottom where it shows the solder seal and refers to large, metal encased, oil capacitors. This appears to refer to large transmitting caps rather than

You have many comments Richard Re The metal cased caps the ad I did not see any “metal cased caps” in what I sent, but maybe my eyes are tired, where is it? Vitamin-Q caps were in ads in 1943, and

A couple of other thoughts: The metal cased caps the ad refers to are probably the Vitamin-Q caps I mentioned. These are metal cases with glass seals on the ends. I would guess from the description of

This is about when molded paper caps were introduced although one can consider the Mica-Mold flat caps that look like mica to be molded paper. Those evidently date from the early 1940s since they are

Richard, also Jacques and all re…..The early one does not list any molded paper caps Here is the first ad I found for the molded caps , no telecap or black beauty yet

I replaced them with BY133s.? Rating 1.3 kV, 1.0A.? $1.64 for 10 pieces at DK. Halden VE7UTS

Thank-you.? I appreciate your response as I do all feedback I receive.? I've gained a terrific amount of knowledge on these radios from this group and all of its contributors. Those caps had been

Thank you to all who replied. The diodes have been sourced and purchased. 73, Jeff W8KZW

Hi Jeff, You can find the NTE506's on eBay,? 20 for $20 Or *Digikey will sell them for $2 ea ( https://www.digikey.com/en/products/detail/nte-electronics-inc/NTE506/11651427 )* Otherwise, if it were

FWIW, I have a couple of hard copy "Radio's Master" catalogues. Others are on the worldradiohistory.org site. The ones I have are 1947 and 1953. The early one does not list any molded paper caps, the

Paul There is a tiny bit of backlash but not bad at all. The piano string on this one is in really good shape. I am thankful it did not need replacing. I do need to align the dials properly. They were

indispensable, is BASS FIDDLE ROSIN. I treat those pesky dial cords with it, and they NEVER slip thereafter.? Violin and Cello are too hard a compound... use the BASS stuff. Tom - W?EAJ

Dan: I would check the following capacitors? C4, C6 , C8. These all appear to be bypass capacitors going from B+ to ground. I am just thinking if they were leaky or shorted they might cause the

Excellent - now let's hear WWV on 2.5, 5, 10, 15 and 20? :o) My SX-100 still struggles a bit with this task. I do know I need a better antenna for sure. [email protected]> wrote:

Looking to purchase subject diode for my power supply. Maybe 1 or 2 extra just to have around. Please reach me off list. Thanks, & 73, Jeff W8KZW

Keith, How much main tuning and bandspread tuning dial backlash do you notice? I need to dig into my SX-100 and replace several bad caps. Then to try and disengage the anti-backlash gears which had

After much patience, the SX100 is working nicely. Very pleased with the results. Pays to not rush. Thank you all for the pointers. Still working on final tweaks, but it’s playing now where before,

Yes, that was an early test.? Yes, the noise was still there.? I previously had biased off the first mic stage and the noise disappeared, so I concluded that it wasn't coming from the audio strip.?

The noise if being observed (visual and audible) on an external transceiver spectrum scope.? The signal is being sampled at a sampling port on the dummy load and is applied to the monitoring
