Re: FT-101E conversion to 6883B finals
|
Hi Dan,? Very good on the test bench set up. The dim bulb test should work fine. I don't have much in the way of test equipment ... a B&K isolation transformer, a digital 200MHz disk channel scope with built in signal generator (that's handy), a couple of multimeters and some insulated trimmer adjustment tools from my TV/radio servicing days. I found out in short order however, that they weren't insulated enough to work around high voltages. I got but a couple of times while neutralizing the new finals. It took two layers of shrink tubing for isolation. Live and learn I guess.? I got some smoke once towards the end of my rebuild. It took me almost three days to find the source. Had the rig on its side, heard a quick snap and saw a little puff come up from ..... somewhere. After inspecting EVERYTHING,? under magnification, and finding nothing I turned it on again and found I had no audio. It turned out that I had lost the AN-214 audio amp .... no visible component damage though. Anyway I replaced that and it came back to life.? I also had to build my own .156" pitch extender cards. I designed 4 double sided cards and bought several dual position edge connectors. The 101E uses single position connectors but I figured dual position connectors would be more versatile.? Anyway, I've rambled a bit here so I'll let you go. I need to get my antenna back up on the roof now that is cleaned and tuned. Good luck with getting your rig back in service.? 73 On Mon, Nov 13, 2023, 6:26 PM Dan KK7JNR via <stockupdate2006=[email protected]> wrote:
