marshall avt50h schematic?

[mrwhy]

Hey you guys who have fixed Marshall AVT Amps!

I got the schematic from Enzo - MANY thanks but my problem is locating things on the main PCB.

My 40, 0, -40 main power supply is FLOATING (at 2/3 of the ECC83/12AX7 B+ above chassis).

Thus the conducting path clearly shown on the schematic is open.
The path that joins the centre-taps of the two transformer secondaries.
But I have searched for many hours and cannot find any such connection (track or link) either on the main PCB or via any other board. Nor any sign of a burn.
Is it hidden under that muck they use to glue the smoothing caps down?

Many thanks

AVT-50 Schematic

Hi all...I am troubleshooting the Marshall AVT-50 (no output) and in need of a schematic. I have tried some of the links posted elsewhere here, but I guess they're all must be outdated. If anyone has a copy, please post the link here, or better yet, please send to my email address at danielnguyen69@yahoo.com. Much appreciate !!!!

the reverb box came loose inside my amp and the screws shorted it out...anyways, i'm trying to fix it and it'd be a lot easier if i could get a hold of the schematic...
can anybody help?

I seem to be having the same problem with my AVT-50h.
No reverb at all.
Any help with this fix would be Greatly Appreciated!

Moved one thread from tubes/valves, discovered another here and merged both into a single avt50h schematic thread..
