Audio Research Tube AMP Reliability

I was out shopping for amps this weekend, and I ran across a guy getting his ARC tube amp repaired.

He said he really like it, but he has gone through tube replacements, and he had the thing burn up on him, the power lines on the board had smoked and burned. I saw the splices on the board, the damage was pretty big, and about $500 in repairs.

The owner of the shop said he got in ARC amps often due to poor design and reliability.

I am interested in ARC because the reviews are great, but I was wondering if other folks are having trouble with their ARC Amps?

How about the Pre-Amps?

Thanks,
Scott

Because the ARC tubes are so expensive guys buy elsewhere.That is where 75% of the problems lie.ARC is in the top ten,maybe top 5 for reliability issues regarding their tube amps.Keep on keepin on and best of luck,Bob

well I suggest you contact the people who worked on it to go through the amp again and check the amp for proper output at clipping as this doesn't make any sense...

I have been using my ARC Ref3/Ref110 combo for the past 18 monts with no problems whatsoever. Amazing stuff.

Years ago, I owned a D-250 Servo. After a few months, with not that many hours on the stock ARC 'selected' tubes, a loud dramatic explosion occurred with smoke, etc. I had to send "Big Bertha" back to Minnesota for repairs. When it returned, I sold it.
I own a pair of M-100's and a custom modified D-79A. I've never had any problems with them at all. They have individual tube bias. I've retubed them with reasonably priced tubes from reliable sources.

The M-100 run very hot you might want to put a fan on em. Can you still get the 7119's from ARC?
