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,

I can't speak for the newer amps but I used to own a SP-6A in the late 70s for many years and had never had any problem with it. I also have friends who used to own different early model ARC tube preamps and none of them experienced any major problem other than normal problems due to aging like noisy volume control, dust collection, dry up capacitors, aged tubes, etc... So I would say the early models are quite reliable.
Never owned one; first time I have heard that "rap", but IMO, the horizontal, stacked output tubes in some of the ARC amps is asking for trouble for all but the bottom tube.
I have owned many ARC amps and preamps over the last 35 years. I have found them to be very reliable. The few malfunctions I experienced were tube related, not faulty circuit design or reliability issues.
A friend had the VT200, the tube blew, took out the resistor, but burned the board and replacement was not cheap...over 1K...I would never own one like that. Other designs of ARC seem more reliable. Jallen
I've been using a LS2BII pre and and VT130 power for 15 years. A resistor blew on the VT130 due to a faulty tube but Audio Research sent replacements within a few days. If you can solder, very easy to fix. I also use SED Winged C 6550s and 7308s in the VT130 with no issues. The LS2B has been flawless.
