I would suggest going to Andy Bouwman at Vintage Tube Services for your RCAs and for his recommendations as well. Buying tubes on the internet can be a crapshoot; Andy has the real deal, and his advice is priceless as well.
Tube Life Artifacts
I've been using the same tubes for almost 12 years. They are RCA EL84s (6bq5) in 1959 Leak TL12 plus monoblocks. Recently, I have noticed that one channel seems to be "deeper" in soundstage, almost like there was more reverb on that channel. It's a mild difference, more noticeable on some recordings than others. This difference is consistent with both vinyl and CD, and switched sides when I switched the speaker connections.
Is this evidence of tube deterioration? I have a set of unused Philips tubes somewhere in the basement (made by Mullard, I believe) and I'm about to switch them. If I can find them...

Thanks for the advice. I'll check it out. I've been looking at these, including Telefunkens at $190 per pair. Seems a bit high, no? http://www.audiotubes.com/6bq5.htm I have no relationship with this seller, and this link is not an endorsement. I posted it for information purposes only. (not sure what the rules are here). |
