Electro-Harmonix 5U4GBEH | Short life Russian tube


Had my '72 Fender Vibrolux Reverb refurbished, including all new tubes. This EH-5U4GB rectifier lasted about 2 months with only a few hours of use. Disappointing indeed.

Very good Dual diode for Mesa guitar amps


Same as Mesa branded tubes rectifier that came with the amp but lot cheaper!
And probably good enough for any guitar amps.

Thanks for the very quick shipping
