My Audio Research experience


To all you goners out there, here is my experience with Audio Research.

Approximately four years ago I purchased an AR Reference 75 power amp.  It was on special at the time and I bought if from a dealer in Brisbane, Australia.

I used the amp for the rear channels of my home theatre system which I only use occasionally because I travel a lot for work and I mainly listen to music.

One night I switched the amp on and a white flash and burning smell came from the amplifier and it didn’t power up.  I thought it may have been a tube, and because I had no spares, I reported the problem to my Brisbane dealer and via email to Audio Research.  A copy of the reply sent from AR on the 5th March 2016 follows:

'Thank you for choosing Audio Research and the REF75. I suspect you had an internal tube arc. The internal tube short can also take out a plate or screen resistor. So just replacing the tube will not fix this problem. The resistors also need to be replaced. You can confirm this by checking the bias for this tube. If the bias reads zero, a resistor is open.  This is an easy repair that our distributor in Australia can do.

The SE update for the REF75 comes with a complete new set of tubes including a new set of KT150s.  This is the only way it is sold. If you so choose, Our Australian distributor can also install this SE upgrade for you while the amp is in for repair.'

I then proceeded to order some more tubes to see if a replacement tube would fix the problem.

I ordered the following tubes:

2 x Electro-Harmonix 6H30Pi Gold with Matched Triodes (Balanced)

4 x KT150 Power Vacuum Tube - [Matching (10+ tubes)]

4 x KT120 Power Vacuum Tubes - [Matching (10+ tubes)]

When they arrived, I tried the new tubes but they didn’t fix the problem as the amplifier failed to switch on.  I then contacted my dealer and freighted the amplifier to Brisbane for repair.  This was done in June of last year.  I included all of the above tubes in the package in case they were needed.  I also would have liked the amp to be upgraded to SE status using the tubes supplied if possible.

In September/October last year I enquired about the status of the repair and before Christmas enquired again. After again emailing AR, I was contacted by the Australian Distributor who told me that the service agent in Brisbane had been trying to get parts for the wrong amplifier and that the amplifier would be transported to Melbourne for repair.  I asked them to get me a price for the upgrade using my tubes.

In January/February of this year, I was contacted by the Australian Distributor and had to supply proof of purchase because there was a dispute over whether the amplifier was in fact under warranty when the fault occurred.  I again asked about getting the upgrade using the supplied tubes which were still with the repair agent in Brisbane.  Eventually I was told that I could have the upgrade using AR tubes only, for the heavily discounted price of $3,000 Australian.  Nothing like gouging your customers!!!!!!  Especially when I could have bought a small car for the original cost of the amplifier in Australia.

I chose to just get the original amplifier repaired under warranty which I was told needed a new main circuit board.  This week my amplifier finally arrived back home after nearly 12 months away for a repair under warranty.  The original tubes have been put in a box with ‘Faulty Old Tubes,’ written on the box.  The tubes I sent with the amplifier have not been returned, and no replacement tubes have been included.

I am amazed that the initial fault destroyed six tubes, so I have asked how the Distributor tested the tubes to determine that they were faulty.  I am now left with an amplifier that doesn’t work and 10 expensive vacuum tubes missing somewhere in Australia.  I am also left with a conundrum, if when I finally get my tubes back and use them to ensure the amplifier works, what happens if it doesn’t.  Will AR then blame me for any fault that occurs on power up because I haven’t purchased tubes from them at their heavily marked up prices????

For me I will never touch another Audio Research product for as long as I reside on this planet.  I will be telling all my audiophile friends and putting this report on every forum that will publish it.  Best of luck for the future Audio Research and may you drown in your policy mess!!!

Why should amplifier manufacturers consider that they are the only ones that can get the correct tubes. I used replacement KT120’s that are only manufactured by Tung Sol anyway so why insist that you must purchase them from AR when they have to buy them from Tung Sol. If they couldn’t be used why have a bias control????

thazeldean,

I got the impression from reading your original posted message the amp was repaired under warranty in your country. Is that correct?
Did the repair center send you paperwork stating they did indeed install a new circuit board and replaced any other parts they found defective? The amp was indeed repaired?

If you lived in the US and sent the amp to ARC, here is what may have happened if you refused to let ARC install their tubes in the amp to complete the repairs of the amp.

Should replacement vacuum tubes be required to complete a repair or update, only Audio Research tubes will be installed in order to assure product performance and to validate the 90-Day Limited Service Warranty.

If a customer refuses the use of Audio Research parts and/or tubes needed to complete a repair or update; the product will be returned unrepaired at the owner’s expense.

ARC buys the power tubes from a vendor that agrees to test the tubes and select tubes that meet ARC’s minimum spec requirements. At ARC the power tubes are burned in for 48 hours before they are then retested again to make sure they meet ARC’s specs. The tubes are closely matched to tubes with the same tube characteristics for push pull circuit/applications. This extra testing process costs money.

What testing procedure/process did the Vendor use that you bought your power tubes from? Not all tube vendors are created equal.

Is it also part of their policy to keep the customer's tubes?

My understanding the amp was not repaired by ARC. It was repaired by an ARC distributor in Australia.

In September/October last year I enquired about the status of the repair and before Christmas enquired again. After again emailing AR, I was contacted by the Australian Distributor who told me that the service agent in Brisbane had been trying to get parts for the wrong amplifier and that the amplifier would be transported to Melbourne for repair. I asked them to get me a price for the upgrade using my tubes.

In January/February of this year, I was contacted by the Australian Distributor and had to supply proof of purchase because there was a dispute over whether the amplifier was in fact under warranty when the fault occurred.

 
Who has the OP's tubes? My guess is the Brisbane dealer may have them. Like I said in an earlier post I would start there.

I have no plans moving to Australia but for educational purposes, why don't you contact the Australian Distributor and let us know.

This thread is IRRELEVANT if living in North America.  ARC service is 2nd to none!
