Need Help: .50 Caliber + preamp tubes positions/functions?

[Sludgenutz]

I will try to keep this as short as possible...looking from the rear, the amp the pre's are lined from left to right...beginning from the power cord side:

POWER CORD SIDE
(A) 12AX7
(B) 12AT7
(C) 12AX7
(D) 12AX7
(E) 12AX7
INPUT JACK SIDE

I am assuming :? from previous "searches" that (E) is the V1 position?

I am assuming that (B) 12AT7 is for the reverb.

There is a phase inverter in there somewhere?

If any of this is incorrect, I am all eyes and ears. I thank you in advance.

Well, no one replied, but I am not phased. I am a embarrased that I got the tube positions completely back-asswards as I was looking in the amp upside down and reversed. :?

Anyhow, I have corrected the post above, so it should make more sense, if anyone cares to reply.

Sorry it took so long. V1 is closest to the input jack. V1, V2, and V3 are preamp tubes, V4 is the reverb driver, and V5 is the phase inverter.

Thanks, Hanson !

Many thanks bro'! I had some idea this was the case, but assumptions count for nothing.

You have made my world a better place.

Look at the one that says caliber 50, that's the right schematic for a .50 caliber +
