Home Tubes Asylum

Questions about tubes and gear that glows. FAQ

Stacy, I am using the Russian tubes in both the Acrosound Stereo 20-20 and

in the great ASR 433 that you sold me with zero trouble. I ordered two quads, from Eastern Europe on ebay, thinking that, having the same date codes, I could match two pair from the eight that I bought.

As it turns out they were all very close on my Hickock 752, which of course is no curve tracer. They have remained well matched and there is no indication of current hogging by any of the tubes in the pairs. They claim 10000 hour life and that they are actually 7189 equivilents which are the uprated EL84/6BQ5. The Acro runs them in class A and I have no issues at all to date.

Perhaps Mr. McShane sells them.
