All my ECC83's are Russian Sov-Teks
Moving onto the old EL-84's. They were Russian made Electro-Harmonix. I replaced them with the JJ's. I was going to replace the rectifier tube, but the factory had already used a JJ there.
Fired up and she sings with the new EL-84's.
Now need to pick up the Silverface from the shop. It was time to change the original RCA 6V6's after 36 years
