Frustrating Egnater Head

I don’t usually “diss” amps, but repairing amps is a great way to see what amps are built well and what amps aren’t.

This Egnater head came in because it wasn’t powering on. An inrush current limiter had burned and blown up inside, yet the fuse next to it was perfectly fine! Despite the fact that the schematic was in chinese, I was abole to find the problem which ended up being a shorted Output Transformer (something that rarely happens with most other amps). Egnater’s service department was unresponsive by email, and when I did get them on the phone, their excuse was that their inbox gets flooded by spam. They did not think the Output Transformer was the problem, and instead wanted to send a replacement Power Transformer. In fairness to them, they did ship the output transformer under warranty in a timely manner (although they forgot the inrush current limiter I also asked for).

Traynor YGL-31 new caps

Traynor Amps​ vintage YGL-3A head in for new capacitors and a tune up. Gotta love how the top opens up on these amps!

Bent Mesa-Boogie

This Mesa-Boogie came in with a bent chassis and a bunch of broken components. All components were replaced and the chassis was straightened out like new!

Traynor YGM-3 Reissue Mods

This Reissue YGM-3 from Traynor came in for some modifications. Notice the printed circuit board that’s used like an eyelet board. The board has no traces on it, and all connections are made with wire just like the original. The silkscreened legend is a nice bonus!

Victoria 5E3 making weird noises

This Victoria 5E3 clone (Fender Tweed Deluxe) came in making some very weird noises. A simple broken wire was the culprit, thanks to the nice build of this amplifier it was very easy to spot and repair.
