Hi Mike, Before I do all this, The manual parts list specifies a NE-83 neon bulb. The schmatic says NE-83A in the V2B circuit, and a NE-83B in the V6A circuit....
Fred, I think both glow-lamps in the SB-620 are the same. I have a strong hunch that the "A" and "B" markings on the schematic are there strictly to identify...
This is on the Heath Archives at Tempe relative to the NE-83 http://lists.tempe.gov/admin/WA.EXE?A2=ind9912&L=heath&D=1&T=0&O=A&F=P&S=&P=46052 Also check the...

The SB-610 and SB-620 don't use 100M resistors. They do, however, use 10M resistors. In the '610, it's used in the Clamper circuit. In the '620, it's used...
Bryan, You're right the modern resistors are much small than the old carbon resistors. The first time I ordere a 1 watt resistors and got them, I wrote back...
It's possible the A's and B's were the 'best' and 'worst' of the batches. What happens if you paint the outside with luminous paint? Does that solve the...

Hello to all. I recently acquired a Heathkit SB-300 that has never been used. IT has been in storage for years. The first thin I notices is that several of...
Hi Wayne,  I picked up a SB-101 a year ago and had the same problem with one of the switches. I tried everything I could w/o removing it - even sitting the...

I have had success with the front panel pointed up, some WD-40 applied to the front of the bushing, and a small Crescent wrench tight on the flat of the shaft....
Hi Wayne. I have had very good success with a soldering iron applied to the end of the shaft. One you get it loose, you can apply lube to the shaft and hope...
Thanks to every o for the suggestions. I will probably wind up a combination of them. Some of the switches are more stiff than frozen, some more frozen. I...
Neil, I still can't shake the notion that the "A" and "B" suffixes attached to the NE-83's in the manual are just Heathkit's way of saying, "this bulb here,...
Hello Heath Group: I have a Heathkit SB-101 that was brought back into service in 2006. It has worked with no major problems, but the S-meter was always way...
Hello again, Fred. I'm curious. Did your 100M resistor actually go out of tolerance, or maybe burn up? I remember we ran into that resistor when we were...
Hello group, I recently started bringing up a DX60B and HR-10 station. I have been able to get copies of the DX-60 manual but I don't seem to be able to locate...

... <snip> I decided to check into a local 75 meter net, and loaded it up into my dummy load. The drive seemed to require more input, and I did not see more...

Sure. You can even use wire and alligator clips for now. But I wouldn't pay much for this - frankly $1 plus shipping would exceed my valuation. You can do much...
I've been trying to buy an SP-99 speaker for some time now. None have come up for sale on eHam or QRZ, and only three in the last six months on eBay. The first...
