Sounds pretty good

What king of attenuation are you using? attenuator or master volume?

ok, so, your complains about the bottom have an easy explanation if you are running with the MVPPI in low settings because you kill the NFB when you turn down the master.

Wow, that sounds awesome.

I saw your one wire mod vid on youtube. Did it to my 68 Metro plexi.
Still trying to get the values right. Mines a little lose in the bass.

Wish it sounded like yours. What are you running for V1A and V1B Cathode resister and cap values?

Thanks

OK, so I'm new to this so please bare with me. So your first two gain stages are jointed at the pin. They are not two separate gain stages cascaded? So I would remove V1b cathode resister and cap ?

I was under the impression that cascading the two separate gain stages via the 1 wire mod gave you more gain.

Thanks, Brian

OK so if I go to a shared cathode. Will the one wire mod still work wired the same way ?

Thanks for the info , I do appreciate it. Your video was the inspiration for me to mod this amp ! (:
