Allen Amplification offers quality repairs of vintage 60s and 70s Fender™ tube amps with a typical turn-around time of 2 weeks or less. All work performed by David Allen, EE and guaranteed. My shop rate is $50/hr and I have a $100 minimum billing for chassis shipped in for repair.


Allen transformers are perfect for repairs and replacements of most of the more popular vintage Fender™ amplifiers or for your own custom-built projects. Period correct voltages and equal or better current ratings. Direct bolt-in replacements with no drilling necessary. Improved features such as Unistrand pre-tinned wiring for easy soldering, center-tapped heater windings on power transformers for convenient grounding (without the need for 100 ohm grounding resistors at the pilot light) and internal hum shield brought out to a lead for grounding power transformers to reduce hum emissions.

The cabinets have a birch plywood floating-type baffle board built up 1/4" on the edges and covered with black/white/silver sparkle grill cloth and have a brushed stainless-steel Allen logo.The cabinets feature a single speaker jack on the upper back panel, bottom chrome corners, heavy duty glides, and a black strap handle. All prices are for unloaded cabinets (without speakers).
