Joost Plugge Engineering

What used to be good,
is still good!


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.
