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
Maybe so. I don't know. The D5 can says good for potentiometers. Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailm

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
Guys, I have Corsair s/n 000349, purchased in March of 1983. 73, Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailm
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

How about one of the AADE (Almost All Digital Electronics) display kits? http://aade.com/dfd2.htm 73, Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.
Jerry: You're right. I hadn't bothered to do the math. I don't have experience with the AADE displays, but they look like quality products. I'm tempted to try one with my Century 22 or with my Heath
I, too, use only Amphenol or other name brands like Kings. There are a lot of cheap import PL-259s out there that are just plain no good. I remember some that had plastic insulators which melted when
I, too, would walk away from it, unless its really, really cheap. Even if there is no visible tar film on it from smoking, it will still stink inside and it will take you some work to clean it. The c
Andrew: It could be the BFO crystal or associated trimmer caps on Double Sideband Generator Board, but most likely it is the PTO itself. Your best bet is to tinker with the value of C9 on the foil si
Andrew: That sounds more like frequency jumps, not drift. In that case I would look for a cold solder joint or get a PTO rebuild kit from Ten Tec. 73, Bob WB2VUF _____________________________________
I believe that the knob was designed by Ten Tec. They have their own in-house die making and injection molding capability. Plus, you will notice that the shaft diameter is not the standard 1/4 inch.

Ye, the rebuild is not difficult. Make sure that your work space is well-illuminated. Do the work in a pan or tray to avoid losing the small parts. The Ten Tec instructions are good, and they even fu
Carlos: Ten Tec replaced the drivers and finals with 2SC1969, but this transistor is also obsolete but still available from RF Parts Co. http://www.rfparts.com/transistors_2SC.html#2sc1969 73, Bob WB
