I have the same problems with VAC : via fb. I asked a lot of questions :. I used 6550 tubes in the VAC. phi 300.1 after weeks ,he said : "it's not allowed to use this tubes instead of KT88. Than I replaced the tubes for KT88: the problem is now solved. Try to go to a tube-amp professional. He helped me a lot. I'm from Belgium , and in Europe there are still a few distributors. Amazing amp.but if you have problems...
VAC and Kevin Hayes are totally unresponsive. What's up with that?
The VAC Rennaissance Signature is the best preamp I've owned, and I've had some really good ones over the years.
Because I like the preamp so much, I tried to contact Kevin Hayes at VAC and inquired about possible factory upgrades to the unit.
I sent the serial number, then he replied and asked for top-off photos, so he could determine which version I owned. I sent photos and then nothing...
Every 2-3 weeks, I sent a polite, follow-up emails and heard nothing. This has been going on since the first week of September...
At this point, even if anyone at VAC ever did reply, I might be reluctant to send them my preamp for fear that they'd have it for months and months and months or that I'd never hear from them again.
Anyone else have problems with getting in touch with VAC?
Thank.
