Hi Rick -- Thank you for the suggestions.

1) Your diagnostics mirror those I received from Gary at TT and from another qualified technician/repairman. Unfortunately, the amp failed multiple diagnostics, and a conversation with Gary Green confirms it requires a trip to TT HQ for a full debriefing.

2) Contrary to assumption, the amp failed right away. It failed after just just few quick exchanges with my relay man in Texas, even before the second check in. DARN !

3) Contrary to assertion, the amp has AMPLE ventilation. I don't want anyone to get the impression it was boxed in. Perhaps you do not recall our previous discussion on this, we worked this over pretty well some time ago. The stand you mention has HUGE cut outs (larger than the vents in the amp cabinet) and is open on the front and back. I added a pair of 120 mm fans to move air around it. There is a four inch clearance on one side, and 10 inch clearance on the other, so there is no chance the amp overheated because it is enclosed. It has better ventilation than if something were stacked directly on or next to it. I am sure you just don't recall how hard I worked to avoid boxing it in as it has been some time since then.


THANK YOU ALL FOR YOUR QUICK AND HELPFUL SUGGESTIONS - All of which confirm it is, as Rick correctly states, outside my expertise. I appreciate all the suggested diagnostics which could be done with a closed cabinet as I am surely disqualified from doing anything inside, especially when it is powered on.


MY ONLY REMAINING QUESTION IS... Is there anything inside that can give me a jolt (like a capacitor that needs to be discharged) while I remove the tubes for shipping ? I would hate to discover that by surprise.


Thanks again... it all helped to confirm it requires a qualified technician to fix.

Happy days.
