[TenTec] Centurion is on the Fritz

[Richards]

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.
