5U4GB, USA, Used/Tested

We have a few of these 5U4Gb, most pulled form Conn organs. All vintage USA made.

A great cost effective way to keep you amp tubed with USA tubes for a reasonable price.  Great as backup for hobbyists or touring musicians.

All used tubes tested very good on B+K 747 tube tester and in actual amp circuit before sale.

Used tubes are guaranteed only to be not "dean on arrival" but should supply many hours of good use.

No other warranty implied.
