My Amp is Broken - Not Sure What to Do - Any Recommendations?


I went to turn on my Audio Research SD135 amplifier the other day, but it will not turn on. According to the Audio Research service technician I spoke to, the problem is a broken Thermal Trak module chip. He said that it is a temperature sensing component, and that replacements are no longer being manufactured. He said that it is a known problem, and that Audio Research will give me credit to purchase an Audio Research amplifier from an Audio Research authorized dealer. 

I was wondering if Audio Research makes anything powerful enough to drive Vandersteen 3A Signature speakers (which need between 100 - 200 watts of power)? I am using an Audio Research SP8 Mk II as a pre-amp.

I don't really have much of a budget and am not sure what to do. I would appreciate any advice. Thank you.

Certainly AR knows how to do it, but won’t. They prefer to sell another amp over helping a customer enjoy their current AR amp for many more years. I think this is a reflection of the company’s culture and attitude.
McCormack is reputed to match well with Vandy speakers.  Here's an upgraded DNA-1 at a good price that should have plenty of power for your 3As.  Best of luck in whatever you decide.

@stereo5 - The oldest that amp can be is 11 years(unless the ARC database is mistaken). It was discontinued in 2010, so- it could be less than 10 years old. NO EXCUSE! http://www.arcdb.ws/SD135/SD135.html
