Ampeg Heritage 50th Anniversary SVT schematic

[Ade Dunlop]

Hi folks - does anyone have a schematic for the 50th anniversary SVT head. Have bought mine to Australia from the US - it has a universal power supply, but i can't find a schematic to work out the color codes on the primary. Can anyone help?
Many thanks, Ade

I would think it should be the same as the other amps, VR, CL, etc. The transformers aren’t different on this model over a standard one.

Do the colors match this? Might also be worth a call to ampeg tech support to verify so you don’t toast a new amp.

Thanks Coreyfyfe - for the schematic - v useful - especially the bit saying delete the polarity flip switch.
I tried emailing Ampeg - they said take it to an authorised Ampeg service centre. The colours are different in my one - i think i have worked it out. Much oblidged!

This should help. Of course, the fuse and plug will need to be changed.

and one more big thank you Mr Beans! - I had it 1/2 worked out - but not the filament transformer - so the table was very helpful - have been playing it for a month now - all good. V much obliged
