TeaBag Pass M-2 clone up and running

Tea, its up and running. Offset is 0.0 in one channel, ran out of pot at 3.5 mv.

Source resistor at .67 or so.

Amp started out murky and laid back, quickly snapping out of that, stage coming forward, expanding with bass picking up. Needs more run in time.

Starting to produce killer sound...

Thanks for your efforts, everyone: you are going to love this amp!

Funny, the first 15 minutes I thought it sounded dreadful and clouded. Then it comes alive. I noticed this only on the first cold start.

Sounds like you could mess with R7 or something if you wanted to shoot for near nothing offset. Keep in mind to all that when first turned on, there may be 300-400mv offset, but then as current actually conducts across the fets (2-3 minutes) and the thing might generate sound it narrows down the offset once it hits current of 660-680mv you see.
So mine is set at the been running 1hr time frame and then checked and tweaked again later, so I judge and set offset once the innards are warmed up.

Maybe I missed this information but I would like to know how long it will take till you
send the PCBs to us?

Thanks!

Important detail.

Tommorow I will order the boards and the transformers. The turn around time on boards is 2-3 weeks till I see them, then I take up to a few days to ship them out ( assuming a weekend).

The factor that is unknown to me, and doesn't affect you , is how long the edcor transformers will take to show up. They say up to six weeks, so I hope it takes less, but assuming it takes six weeks since I will be ordering close to 100 units.
