Vintage Radios & Amps

In addition to building tube amps, we have been  selling  and repairing  vintage broadcast and shortwave tube radios and vintage audio amps since 1952.  Our tech library has 1000's of old schematics and the "old timer" techs with over 60 years of experience to repair the toughest jobs.  Some of the  radios and amps   are believed beyond repair when we get them, but we bring them all back to life!  Contact us for more info at frenzeltubeamps@gmail.com
