Rectifier for 2A3 Power Amp

By: on 28 October 2026
Purchased from Evatco installed in Home Brew 2A3 single ended power amp , no hum whatsoever . This type of amp is notorious for heater hum , possible larger voltage drop across Rectifier compared to NOS 5Y3gt .

Product not up to scratch

By: on 30 June 2020
I bought this valve in late 2019 for a Tweed Deluxe (5E3) project along with a whole bunch of parts from Evatco. The amp sounded great but had an annoying hum. I eventually traced this to the rectifier tube. When replaced with a TAD 5Y3 premium selected valve, the hum disappeared. However I was pleased with Evatco and the other products purchased.
