Derek92994's 700 Ser II White Oak conversion

To clarify, to220s pins down writing towards you, B,C,E pins in that order?
 
Base on left, not sure on the other two without a data sheet in front of me!!
 
Assuming the to220s go bce left to right:
To220 bottom left
B- to E+ 1490
B- to C+ no value
E- to C+ no value
B+ to E- 584
B+ to C- 584
E+ to C- 491
To220 bottom right
B- to E+ 577
B- to C+ 575
E- to C+ 753
B+ to E- 1520
B+ to C- no value
E+ to C- no value
 
No, they are not, I see some tears. Get some of those and a new output. Got a source there?? Don't get just 6 sil-pads, get 30, 6 for now and 24 spares. Do you have spare AGX 5 amp fuses?
 
Got spare fuses, will chase up outputs and sil pads
 
By the way, I believe if a fuse blows, its best to investigate, not just replace, they blow for a reason :evil4
Main power fuse I can understand, replaced one of those from turn on fatigue.
 
After you put in the outputs, set the amp like normal and take some isopropol alcohol after the rosin on the backplane . Short, stiff bristled brush, and dip and scrub, they're called chemical brushes here.

Once I have replaced that output, and sil pads, do I bring it up on the variac?
 
So outputs can just go even if not stressed all the time?
 
No DBT here. But yea will use variac. Thank you for your time bud, its great to get some clarity and a solution

Darc, I've roasted some that were a week old.....got them really hot of course, but yeah, when ya push stuff hard, shit can happen....and who's to say it was as good as the rest....just never know....that's why we love DCP boards. If you had one later generation backplane you wouldn't have to solder in outputs....THAT IS A PITA.....youre doin good Darc..

yeah all the practice helps bud. So lucky for DC protect. The outputs got easier to remove 2nd go. No magnet either.
 
Build a DBT, a variac will limit voltage BUT NOT CURRENT....you can tell if you're coming on against a short with a variac but you have to pay close attention and listen to the beginning of the squeal...

And you are very welcome Darc....really glad I can help and be successful...
