Metropoulos Amplification is dedicated to building the finest replicas of vintage Marshall amplifiers available. Discerning guitar players are using our recreations and leaving those valuable plexis at home, where they are safe. We also search out and supply restoration grade parts to builders and DIY'ers in our online store. There you can find all of the parts needed to restore classic amplifiers or build one from scratch. When NOS parts are no longer available, we have them manufactured.
Our amp kits feature accurate chassis layouts, vintage spec transformers, correct component values and step by step instructions that are second to none. No corners have been cut and the tone is world class. Compare them to other kits available and we think you'll agree.
MetroAmp provides an online community for amplifier discussion, tech support, and kit building help - join the MetroAmp forum today. We have also opened the Vintage Amplifier & Tech Wiki, a permanent archive of diagrams and knowledge covering vintage amps through to today's amplifiers. The Wiki is constantly growing as users add information.

The MetroAmp Vintage Amplifier & Tech Wiki has now been opened. The wiki will provide a resource for anyone interested in vintage amplifiers, or anyone who builds and repairs amplifiers, kits, and replicas. Site owner George Metropoulos says:
I believe the wiki is THE 21st century solution to archiving vast amounts of technical data. In this case, all the info techs have scattered around the net can be assembled into a central location. Need a schematic for a tweed Fender? Need to date a vintage Celestion? How about the maximum plate voltage for a 12AX7? I envision all this info and more available in just a few keystrokes.
