Guys, I have Corsair s/n 000349, purchased in March of 1983. 73, Bob WB2VUF I cannot say when the coded SNs started, but can supply you with the numbers I have. I acquired Corsair #1 a few years ago.
The Corsair speaker line uses small shielded cable. For audio, you can't beat the the old tried and true inline male and female "RCA phono" plugs. Heathkit used them for many years, even for RF. (The

My Corsair schematic shows 500k, but not whether it is log or linear. The parts list only has active components. 73, Bob WB2VUF If its 250k and you put in 500K, you extend the LF range of the notch b
In that case a dual gang stereo volume control pot should work. You still might be able to revive it with contact cleaner or De-Oxit spray. Bob WB2VUF 73, Steve G3TXQ So you're saying that the double
Thanks, Jerry. I didn't know that about DeoxIT ..Bob WB2VUF Steve found a pot at Maplin with it looks like the perfect specs to fit, needing only that the shaft length be trimmed to fit. I'm thinking

I've used the DeoxIT D5 spray. I works great in flashlights and battery packs. I've had mixed results on the potentiometers in my Paragon; they always get scratchy again in short order. Maybe it's ju

I have the 4-pole filter that came out of my Corsair when I replaced it with a 8-pole one. It is 9 MHz, has 4 crystals and 5 caps. The PC board is marked "6840" (had to use a magnifying glass to read
Wow! John Brune and his sidekick John Gratalo are the guys that I ran into at Lakehurst NAEC in 1981 where they were flight testing the system. I didn't know that they were famous. When their project
