Ratings & Reviews
Very good Dual diode for Mesa guitar amps
by Andre R.
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
Short life Russian tube
Had my '72 Fender Vibrolux Reverb refurbished, including all new tubes. This rectifier lasted about 2 months with only a few hours of use. Disappointing indeed.
