Elrog ER-211 tubes 1.000 hours use

Well I have a pair and after 800 hours use they both became extremelly starving with Bias tension. They became to sound extremelly well until one of them is now running out of parameters, is dying ..
Well I'll try to get a single valve at least. One is so hundry that is running out of Bias.

Anyway I'll also try some of the new chinesse prestige series and listen.
Well after hearing GE VT4C a couple of days, I decided to go back to the Elrogs that are much better sounding even having one out of bias.

I'll be patient and read about PSVane WE211 before purchase.

(Hungry for bias; not hundry sorry ..)
