All the caps have been replaced. Applied power today and have great voltages coming out of the filter cap. Actually right at spec which was nice to see. Have a brand new 5y3 rectifier tube in place.

Hello to All, I'm continuing to work on a HT-32B, that had previously been set aside as, a parts rig.? I suspect I may have a bad VOX relay. I've checked the resistance on the coil and it's showing

Hi Floyd, I have one in my IC-751A now, but haven't tried it in a tube rig yet.? I don't expect the squarish wave to be a problem.? Crystal oscillators typically generate plenty of harmonics, so

Hi Floyd If you take the 35.0 MHz crystal in the adjacent socket out of the radio, does it still do this? Halden

Hi Richard, Not a crack: just a mold seam. But they all leaks heavily when tested. The PIO failure mechanism is that the impregnation oil absorbs the ambient oxygen. A very slow process, indeed, but

I found a nice chart showing the color code. See: <https://ridelikesk.xyz/product_details/11678262.html> -- Richard Knoppow Los Angeles WB6KBL SKCC 19998

There is an article in the latest ER mag about using this part in a Heathkit. Looks very interesting. I too was wondering about the square wave output as sq waves can generate a lot of noise /

It's about time! Your collection is overweight with Collins...;-) 73, dave wa3gin p.s. Walt I changed the value of R326 in the voltage divider and now bias current is perfect at .200 amps when

I wonder if anyone has used a ProgRock "crystal" in any of their Hallicrafters receivers?? The current units are similar in size to a real crystal in? HC-6 holder.? They generate square waves, but

I picked up a couple SR-2000 radios today. Radio number one partially tested Power supply has new caps and makes 1100v and 1700 to 1800v Indicated. USB rx is OK LSB is way off freq on dial and can't

Just when I thought the SX-117 was finished: I just received the crystal (34.5 MHz) from AF4K.com to add 28.0 to 28.5 MHz coverage to the SX-117.? The crystal oscillates and I can get the required

An update on my HT-44 VOX delay issue: I raised R2 to 163k in an effort to remove the blip that had appeared on the CAR oscillator onset in VOX mode. That worked, but the key-down to full RF delay was

Those are the ones, thank you for identifying them. C-D had a good reputation but so did Sprague. Evidently something went wrong. The one at the top has what looks like a mold seam but could be a

Richard, When you wrote: I don't know who made the white molded caps with stripes shown in some illustrations of the SP-600 or whether they suffered from the same problems. Did you really mean pale

Thanks for sharing this! It really did help. I am hoping it will be more accessible when the faceplate comes off, but not sure. May have pull it out to replace them. But that will be last thing. Want

Don't know. The cases are probably Bakelite but most Bakelite objects do not disintegrate. Something was done wrong in the composition or molding of the cases which caused them to crack and split
