I’m not a big fan of supporting communist regimes, but it holds my shit and hard to justify a panavise for two or three boards. Just woke up for a pee, can’t even hold it all night any more ffs. Slapped some stain my friend had kicking around on the rough 2x6”, a little hand sanding and pounded some tunes, had some beers and rum. WOPL’n later today maybe, need my brain working for that shit.

Windows for sale. As is, where is, $50 for 4, take all or none, not negotiable. o_O:cool:

Damn,woke up “speaker lubricated”. Back to bed.

Could have filled it with some nice olive oil! Moved 4 light switches in the kitchen today. They were always in stupid spots but were gonna end up behind some furniture I got from my folks move. What a mess that made, effin drywall... new oil seal came in today for my 1946 generator too. Turned the commutator/slip rings and have a brush holder to repair also.

Ok so I was a bit distracted from this, then some friends came over when i was let out of coronAIDS jail and “cleaned” the kitchen table which was OK, just glad I had all the components back in their bags so nothing got too mixed up.

So I’m just looking at how to proceed here and having a coffee so my brain isn’t fully engaged just yet, also disclaimer, I don’t have the manuals in front of me rn so forgive me if this is a stupid question I should have looked up first... someone has been at this original board... are the bias transistors not mounted on the back wall in the 700/1? Same as the 400/1? In the P-straps? They connect to the WOPL board C-B-E L/R connections? If so, someone has mounted them to the original PL board. Also, I looked over your email Joe, I don’t see any mention of the level potentiometers making connection? I probably just need to re-read the manuals so again sorry if dumb questions!

No backwall mounted bias transistors on the 0171 board. How they tracked heatsinks temp on the driver board is a long held mystery. So....you are short p-straps?

Yeah, if they are to be mounted to the back wall. I can rob them from Linda for now. Broken-out the manuals and been looking at the schematics and the wiring. Think I got everything traced out to make the board connections except for the level pots and meters. I gotta cut the ties in the original wiring and separate it all to really chase it out. Found a near short to ground on on of the thermal switches too. Close call there. Someone’s been at this amp before... anyone got the install instructions for the 700DCP? I got the 400 instructions somewhere, wasn’t too complicated, just want to make sure I don’t miss something stupid...
