Sorry to contact you this way, Klaus. I know you don't really monitor emails and when I called earlier this evening, I couldn't leave a message because your voicemail was full.
If you wouldn't mind letting me know the best time to call you to discuss getting my Stratos Mono Extremes shipped to you for service (I'm experiencing a hum in both amps -- probably transformer-related) as well as talking about additional work to upgrade the internals while you have them, I'd be very grateful.
(I just checked my phone ... did you try to call me back around 7 pm EST tonight? If so, then I missed your call, too.)
