Well
I am still taking a breather after 38-15, but tonight I was bored out of my mind and the choice came down to:
1. Rummage through the fridge
2. Have a 250 calories worth of an Irish ale, or
3. Start on the tube checking.
I chose the latter.
Now the very first tube, the 5U4, of course, what else, it sticking as a you know what naturally I picked it first, it tests DEAD. And dead means - reeeely dead. No movimento absolutamente. None.
At tbe same time it gets hot and the filament really drags down the Line indicator. Which I figure is probably OK. But no emission, whatsoever? On BOTH diodes? Weird I say.
Anyone seen'em like this, heating and full dead? (I did check for shorts, it is good).
There is another tube 6J5 that is bad, but it is "mostly dead" being 150 at some 1500 or such.
And even 6A5 output tubes are probably ok at 1500 with 3000 nominal. Both are the same.
I have another few tubes to go through; the thing is dirty as heck and one tube had pins oxydized though tested fine. And the extraction is a bit difficult.
Well as we say, "a woman had no worries so she bought herself a piglet".
Gonna be fun!
