Greetings to all,
Will said about salvaging shorted tubes, "The only problem I thought
of though was that the tubes grids could have a gap in them created by the
arc thereby stopping so much of them from working at all." Good point! Of
the tubes I have salvaged, I have never compared them to new ratings. I was
always very pleased when one worked at all. Most of these "rejuvenated"
3-500Z have been ran in SB-220's, Henry's, or TL-922's. None of these amps
run the tubes any where near there max, so a little damage to the tubes
innards is easily made up for with just a little bit more drive. I have a
pair of "rejuvenated tubes running now in an HL-2200. I get approximately
1,300 watts out on 80 meters with 100 watts drive.
