Just checked bias again .349 Left .357 is the lowest I can adj. the Right.
DC offset is 13.6 on the Left. - 007. on the Right Don't really understand the - reading. Polarity on the meter is correct. Don't think it makes a difference but you are the authority on these amps..
Down below I wrote about getting all new OPT. Do I need to do that ? I would just as soon not if I do not need to. And now some more news. A careful check of the shop revealed that I did not throw away the Mica insulators. I found plenty to finish this amp, brand new. I did as you said. DBT/Veriac check bias / dc offset. After warming up about 10 min or so I have.
Bias Left .353 Right .357 that is with both pots turned all the way to minimum.
DC Offset Left 12.5 mV. Right 1.0
This is with all 909 transistors in. 120V AC pulling 0.05 A at idle. Update. AC/DC sounds great so I moved on to a real test. Bolt Thrower, Hard to stay in the shop for any period of time..Had to turn it down or go deaf. Then Oh yes..Mastodon sounds great too. Amp stays cool even running it at 80 watts or so for long periods.
I thought it would not matter so much about the OPT as I had that DC protect in place but that was why I was asking in an earlier post today do I need to order and change out all the OPT. Should I just run these and don't worry about it or get all new ?
Well. it's a case of "where do you stop". Everything needs replaced in that amp as far as us White Oak nuts think. But if you aren't going to run it hard, I'd run it as is. Until it won't run anymore or if you're ready to take it up a few notches....
Well now, I am beginning to understand. To WOPL and beyond. I am looking for that PL 700 Now. Thanks a million all ya'll once again. If I can be of help to anyone shoot me a line. No shit, I got a lot of stuff and if you guys need anything I would be more than glad to help. I will keep my eye on the threads here to see whats up.
