Ampeg SVT VR Transformer Schematic Needed

[kbhag63]

Hello everyone! Have a 2006 SVT VR that had the Power Transformer removed by previous owner, said the amp "stopped working at a gig", I purchased the amp with the power transformer out of the amp. Nothing was labeled when they worked on the amp and took out the PT. My tech is looking for a schematic for the transformer and the color code/spade connector codes to reassemble the amp and he will bring it up on a variac.

I have a few schematics (main board, tube board) but the 07-319-04 power terminal board located on the back of the amp he doesn't have that.

There are several threads about these amps having a low voltage (below 112 Volts) feature on them, we want to reassemble the amp to factory and then test to be sure it wasn't just a wall current issue.

Thanks for any help in advance,

Ken

The mod to bypass the low voltage problem is documented here: SVT-VR (homestead.com)

The PT info is from: Compiled Ampeg SVT-CL, -AV, -VR, SVT2-Pro & SVT II Svc Notes...347 pgs - Music Electronics Forum

I haven't seen the VR Chassis Assy schematic for a few years. If you can find a copy, it should identify the color of the PT wires and which pins they are connected to.

Maybe @beans-on-toast has a copy.

Thank you Wasnex, I do have the schematic you posted but stil do need the chassis assemby schematic with color codes/terminal points.

hopefully beans-on-toast does have a copy.

Thank you again,
