Since I moved, my Sphinx Project 12 Mono....

Block Amp(right channel only) consistently shuts itself down, into some kind of "protected mode" -- between 15 to 45min. after powering the pair up, to enjoy some vinyl. The routine's the same each time: 1) a singular small "click" occurrs inside the amp. 2)immediately followed by one tiny red light turning on & remaining on. I have to turn the amp off for hrs.before it "resets".

These Monoblocks have performed seamlessly, with such delightful characteristics for 8 yrs. Never before have I experienced any fatigue of response,overheating, or problem/issue of ANY kind. Until this anomaly 'self-shutdown' mode, I experienced the bliss of fantastic Micro-detail, with varying degrees of 'wide' & wonderful stage depth. The Sphinx 12's have always made my Vandersteen 3's sound GREAT. An all-tube Pre-amp, the VK-30SE by BAT --is the only thing I've owned, as well.

I'd like to have some idea, if something's in need of a tune-up with my 12's. It's gonna cost a lot of $$$ just to ship the pair to SILTECH in the Netherlands. Anyone know how to reach SILTECH? I've yet to get a response from them via email.

If more info is needed, for a fellow Goner to troubleshoot my scenario here, don't hesitate to ask.

Thanks in advance everyone....
