Oreganpapa,
So what did you think when you removed the covers?
Scousepasty,
What did GNS do to your preamp and what did it cost?
One thing I've noticed about my REF3s is that the sound which is usually open, dynmamic and has great bass, tends to fade away, I at firts thought this was worn out tubes, but I've found a good cleaning of the tube pins with Caig DeOxit and the magic comes back. I've also found that anytime you move or reposition the preamp, the 4 6H30 tubes toward the back of the preamp tend to loosen and hang down just a little bit overtime. The cleaning process and restoring them to their 90 degree horizontal position brings the sound right back without having to retube. I'd not be surprised if this is where the discrepancy between ARC's claim for tube life and other audiophile's findings comes to life. Because of course a person putting in new tubes would probably clean them before inserting and they would be inserted correctly into the tube sockets. And viola, the the spectacular, natural sound is back.
Thanks,
Steve
