JPE

We specialize in the revision, modification and restoration of Quad transistor amplifiers and tuners from the 60s to the 90s of the past century. For a number of Quad models we designed new modules. We also carry out this work on other quality equipment from that period on a project basis. We also supply a number of products to partners. We don't supply parts or components to customers for DIY jobs.
