will I need to mod the bias supply and, if so can I still get enough range to be able to return to 6L6 when wanted ? Also what If I connected a 8ohms load ? The SR sets the bias voltage to -52V. The DR sets the bias to -35V. If your bias pot can swing as low as -35V you're OK. Otherwise, a simple m...

Don't forget you need 10x power to double volume, which also means you need 1/10th power to half the volume. I don't think the power reduction will make much difference in volume. Both setups would be loud when pushed. BUt with more sag ( different rectifier ) and two speakers disconected, would I ...

Would that not result in a 4ohms load ? Or am I refering to something different here ?

I was thinking about that also. Anyone else want to comment on that idea ?

Wondering if I could run 6v6's in a 69 Drip edge super reverb that was reverted form AB568 to AB763
ANd if, so, would there be a significant difference in volume/ headroom. I am assuming I would be getting breakup at lower volume ???

O.K, that.S exactly how it looks form the pics I cab see. THe seller is posting it as a 1990, but according to your info, thaat is not correct .
Think I'll pass.
Thank you !!!!!

Here is a picture of the Label inside the amp

THe amp I am looking at is a 1990 !
THe label inside ( tube complement ) says : Deluxe Reverb-Amp AB763

THanks, I know thats the casewitht more recent ones but I was wondering about the 1990 version witch is labeled " Deluxe reverb Amp" not 65 Reverb

HOw far back do I need to go to find one that has the pots on the chassis ?

Does anyone know ehn Fender started putting all the pots on PCBs ?

I may be interested in a 1990 DEluxe reverb RI but its in another town and the guy doesn'T want to open it.
Would this have the pot mounted to the chassis on on a PCB ?

Thanks!

This doesn't work because the internal pre's sgnal cannot reach being defeated by the loop

ANyone offering a D type preamp ?
:-
)

In the amp I want to use, there is a tube buffered loop in that position.
Could I still use an AB box there do do that without any issues ?

No one can help ?
Just wondering If I need to do anything other than beginning the connection to the PI ?

Thanks

If I want to add a "power amp in" 1/4 inch jack on a tube amp and want to be able to use an A/B switch to toggle between the internal preamp and the external one I would plug in that input, how would this need to be executed ?

Thank you!
