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

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:

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

I have lost track here. Have you just shorted the mic connector to see what happens? If you have does the noise continue? -- Richard Knoppow Los Angeles WB6KBL SKCC 19998

How and where are you sampling when you see the noise. Walt Cates, WD0GOF https://wd0gof.com/Hallicrafters A majority of acceptance is not proof of correctness.

Well, the AALC idea didn't pan out.? I disconnected one end of the diodes and also removed the plate supply from the AALC amplifier stage.? No change whatever.? Also played with the mic? connector

Thank you sir

Interesting idea - thanks, Paul.? Will look into that. 73, Floyd - K8AC
