Get well soon!

Get well!

Update: Desert Amplifier Repair is currently closed while recovering from Covid related medical issues. It’s been a month of long and difficult recovery. Battling pneumonia followed by a transient ischemic attack / pre stroke Sunday. I’m doing ok and should make a full recovery. I wis discharged late yesterday and currently recovering at home. It’s hard to take phone calls as speaking triggers coughing fits. If you need to reach me email is best. I will be doing my best in the coming days to get caught up on emails and hope to return to the shop with at least limited hours sometime next week, as I work toward a full recovery. I know each of your repairs are important and I appreciate all your patience and understanding during my recovery. This was certainly not something I would have chosen to go through by choice.

Thank you,

Bias Mods

Changing the stock fixed bias, found in many amplifiers, to an adjustable fixed bias has several potential benefits.

Tube Matching and Grading

This project consisted of testing tubes for a client. The tubes came from Europe and were manufactured during the end of the Cold War. With the tubes being used in a cathode bias (self bias) amplifier, it was important to match the tubes as closely as possible.

Marshall JCM2000 DSL/TSL100 Bias Drift Issue

The early versions of the JCM2000 were prone to an issue that has been coined the “bias drift” issue. It’s been discussed at length on countless fan forums and since around mid-2004 the issue was resolved in manufacturing by Marshall.
