Thanks! I appreciate your "take it easy, wait and see" approach. Plus, some variac questions

PAINTING: "Death of a General Electric 6550A"

Chris O,

The above painting was done in commemoration of having let an output tube in the D115 run probably a year past it's normal use such that it arced and took a sacrificial resistor with it. Pilot error- audio ignorance. Penalty: five weeks without the amplifier and a $XXX fine.

The problems with my technical ignorance in audio is that I end up being:

1. overly cautious and consequently fussy and obsessive about things I've heard about that don't warrant it and, simultaneously,

2. neglecting things that I never heard about that end up making expensive sparks and smoke.

So, armed with the idea that I'm not likely to do harm, my plan with the D115 is to initially clean the tube pins and plugs and bring it up on the variac. Just to confirm:

1. There will be no preamp connected. I should have the D115 connected to the speakers for the variacalating?

2. I've always been very casual about the variac- how long at each voltage. Thinking back, I have been impatient and sometimes have done this too quickly. So I can gauge whether I'm within a reasonable range- how would you incrementally increase the V's on a power amplifier that's been asleep for 8 years?

I appreciate your "take it easy, wait and see" approach to electrolytic capacitor replacement in the D115. Truth be told, I just moved and don't have the the time for additional projects- it's a miracle I can find a spoon when I need one. And, a further miracle I can afford to put something in the spoon,..

Thanks again!

Cheers,

Bambi B
