MOD50 tube configuration?

[MarcoR]

Sorry to ask this again; I did search… Can someone tell me what tubes are what in the head (specifically which is the PI)? And looking at module with the knobs facing you, the tube on the left is V1 correct?

V1 is tube on left in the module if your looking at the front of it.

My Mod 50 had all Sovtek 12ax7a tubes in all positions in the chasis.

Thanks. I have balanced 12AX7LPS I want to put in the PI position. I know many people say using a balanced tube in the PI doesn’t make any difference but for shits an giggles I thought I’d try it.

The PI should be the closest pre to the power tubes.

Have at it. I don't know if there is a difference, but ya never know....
