WLGMUzza Can I send you a PM? To exchange info on brand/model of the amp. Maybe I can help.
For sending PM I suppose our email addresses should be known by the system. Dunno how that works on this forum.
Are you sure that the diagnostics system is all OK? Maybe it is a bit more 'triggerhappy'...
Following this discussion with interest. My question to WLGMuzza would be, looking at his phrase "the first set that came with the amplifier only making it to 1900 hours before total replacement." : what is your trigger to say that your tubes need replacement? Do they stop working? Or do you...
