Ruby Tubes 5U4G Rectifier Tube is a large envelope rectifier tube for natural tube compression -(aka "sag") with a smooth feel.

Ruby Tubes 5U4GCZ Rectifier Tube is an excellent replacement for Mesa Rectifier series amplifiers.

All RUBY™ Tube power tubes come already matched. There is no extra charge for this service. Our matching process is very exact and our tubes are matched within +/- 1 mA (milliamp) of each other.

All tubes are further QC checked on our own B&K equipment ,and tested here in Cornwall ,in our own shop ,to assure they meet specs.
