Set of 3x matching German made ERA ECC83 / 12ax7 pre amp valves

Unsure of the manufacturer, some people seem to think that they are rebadged Telefunkens, I'm not an expert so really not sure, as I can’t find much info on them; anyhow, set of 3 from the mid sixties - perfect for your Vox ac30,  Marshall JTM45 etc etc

Fully tested by my amp tech, not microphonic and not worn.

I've just noticed that I have a set of these in one of my elpico AC88's from 1965, if you want some audio examples of the amp/ERA preamp valves in action message me!

anything else just ask
