Ampeg V4/VT22 preamp modification

Post by ROB »

Im thinking it would be nice to make input 2 of my Ampeg V4 utilize both 12ax7s for gain stages. Please take a look at the attatched schematic and advise if my idea is possible.

Would it be OK to just jumper from pin 1 of V2 to pin 7 of V1?
Im assuming this way when I use input 2, the guitar signal would run through both preamps.

would this alter input 1?
would I need to disconnect the junction from V2 pin 1 to V1 pin 1?

Is this the best way to cascade the preamps in this amp?

Thanks in advance, your ideas are greatly appreciated.
