Ampeg Micro VL Schematic

[Steve Fundy]

Hello All.
Does anyone have a schematic, or link to a schematic for an Ampeg Micro VR? I am trying to repair one for my bass player. It has very low output. I am pretty sure it's power amp related, not pre.
Thanks in advance!
Steve

Sorry. Don't have that one.
Here is the block diagram.
Use the Send &/ or the Return jacks to narrow it down.

Hello,

These links are now broken, would you happen to still have the files?

Much appreciated!

Hello Steve, would you happen to have these files? Links are broken. Did you manage to fix your friend's amp using these?

I have one with a problem with the limiter circuit. I am thinking it might be the vactrol.

Thanks!

Thank you very much dear sir! Now to debugging this thing... This limiter circuit it a bit more complicated than what I had expected.

[rafammbass]

Although since the limiter circuit does not engage (light does not pop up) I will tackle the FETs first.

Which is ....?
Please describe the problem.

The symptoms, not the solution you imagine.
