Audio Research 610T

I need help, my left amps running problem.
Turned on Standby mode , a minute later found breaker trip.
Reset breaker , power on and found my speaker humming , check V2 section all tubes glowing very strongly across the plate - very blueish ,
check bias V2- 0,
check bias on all V2 tubes, v4,v6,v8,v10,v12,v14,v16  and so on all read 120.
V1 ok.
I replaced V18 with new tube , same problem.
Need advise , thanks.
I have to call ARC on Monday.

 Usually a blown resistor is caused by a bad tube. I would also check the tubes. Your ARC dealer probably has spare resistor on hand.

Big amps, but this problem is not a huge problem.  A fried resistor and maybe a failing tube took it out.  Personally, if it were me (and I am capable for diagnosing and repairing this type of equipment), I would find a local authorized Audio Research Repair facility and take both amp in for repair/checkup.

In LA, there are a places and people authorized by Audio Research. You don't necessarily have to ship the amp all the way back to Audio Research.

Part fail.  it is a fact of life for mechanical and electrical devices.  but, it isn't the end of the world.

enjoy
