Power cable "Break in" question
Like Lowrider57 said. It has to be connected to a load. If you buy one of these you could connect it to your refrigerator. The new power cord needs to be at least 14 gauge wire though.. 
Power Amp Repair Question
They had a $100 estimate fee and I assumed I'd get an estimate with a diagnosis. After one month, the shop doesn't know what's wrong but says I lose the $100 if I want it back. I asked if they might know in 2 more weeks and they said probably not.... 
Heat heat and more heat??
Daveyf,Curiosity killed the cat. Did you disconnect the Sub from the amp to see if that was the cause of the heat?(I assume the heat is coming from the power transistors heat sink fins on each side of the amp.)If you did disconnect the sub and the... 
Hear sibilance on Krall, Famous Blue, D. Fagen?
All is well until she gets to the word "soon [we'll be without the moon…]." The letter "S" in the word "soon" is very strident. 09-04-15: RebbiShe sings the phase twice in the song. Neither passage of the words "soooon, we'll be without the moon",...

BIF,Jim, any idea why the 6922 bias pots are less weird than the power tubes pots?08-30-15: BifwynneThe 6922 bias pots are blue in color only and are not the same pots as used for the power tube bias pots. I believe they are a whole different anim... 
ARC VT-50 Damage/Repair Advice
Hi Al, I suppose it's possible that the physical placement of the rectifier circuit and the filter capacitors could have provided some reduction in the likelihood that a short to that screw would have affected the other channel,Al, That was not a ... 
ARC VT-50 Damage/Repair Advice
Bifwynne,Yes, that is why a pair of hook on probes should be used when biasing the amp.Sometimes I think the guy that designed the layout of the amp had a sick sense of humor. Also as I stated in an earlier post the bias adjust pots are really tou...

Al,Here are a couple of pictures I found on the Web. This picture shows the Phillips head circuit board mounting screw on the right channel that I think the multimeter probe came into contact with causing the short circuit. This picture shows the ...

I'm assuming, btw, that the B+ is generated by a power supply circuit that is common to both channels, which I suspect is the case but don't know for a fact.08-30-15: AlmargHi Al,VT50 Schematic and parts list.Note the two R30 10 ohm resistors on t...
