Service & Repair and Refurbishing services are available for the Drake amplifiers and high voltage power supply.   Services include cleaning, repair or the full refurbishing process.  Need to replace final tubes and/or chimneys ?  I can help.

I can clean & repair and/or rebuild the high voltage power supply.  The rebuilding process includes all new filter capacitors and rectifiers and any other parts deemed bad.  

I stock and install the latest after-market upgrade kits from The Heathkit Shop and Harbach for the L4B or L7 High Voltage Power Supplies.
