Trace Elliot Repair – GP7SM 200W

Trace Elliot Repair – GP7SM 200W

This Trace Elliot repair is actually a service. My solid state service procedure involves the following steps:

  • Cleaning of all pots and connectors
  • Re-soldering dry or suspect joints
  • Any preventative maintenance required
  • Replacement of out of tolerance or defective components
  • Output power test.


I’ve seen a couple of Trace Elliot repairs in a pretty sorry state. The main cause of trouble is normally the ‘bipolar bear’ (bad electronics joke by the designer) output stage. This unit uses a lateral MOSFET output stage that is more reliable, so the customer has little to worry about. I’d recommend that owners of a Trace Elliot amp with the original stage have the output stage replaced at some point if the amp gets really heavy use.

Here’s the owner’s feedback, taken from the now extinct review site ‘’ before it merged into ‘’ and deleted all old reviews!
“ Rowan at Ampworks very kindly serviced my Trace Elliot GSM200 solid state head at extremely short notice. He did a thorough job of making sure everything was as it should be inside, re-soldered any suspect connections, checked the electronics and pots. I can’t recommend Rowan and Ampworks enough.
