I would like to thank everyone for the helpful posts and guidance.

As regards the details of the incident that led to the problem--- I am almost 100% sure that the speaker leads did not touch each other when they were accidentally pulled out, so this is apparently good news. I will certainly look into the straightforward possibility of a blown fuse once I get back into town and get home, and I'll post the results. If that doesn't work out, the Adcom web site lists 2 different retailers in my area who are supposedly Adcom dealers, and I would then pursue that route.

I would love to get that 555 working again, as I was enjoying it as much during year 15 as I did during year 1......

Thanks again..........

Don't forget to ask around about their service dept. first if you need to take it in. Also, do they send their repairs to an outside shop? Go direct after asking about the shop.

Default Adcom blown channel: follow-up

I would like to again thank everyone for their posts and suggestions. The following took place since I last posted:

1. After reading the posts here, I removed the top plate, and I did, in fact, find 2 blown fuses associated with the right channel.

2. I easily obtained replacement fuses and replaced. Still no right channel.

3. I searched the Adcom web site and found a high end retailer located about a 25-30 minute drive from home. I contacted the store, and I was told that they would be happy to help......

4. One month and many, many phone calls later, I was finally told that the amplifier was repaired. I was told that a "circuit board" and "other things" had to be replaced. When I pressed for a few more details ("like, uhhhhh, what other things?"), the response was "I don't know".

5. Before driving to the store and handing over a check for $325, I made it clear that I wanted this informed fellow to show me that the amp was working properly before I would pay him.

6. I drove to the store, and he did, in fact, have the amp connected to other components in one of their main listening rooms. He played something briefly, and it sounded great. I gave him his check.

7. I drove home, carefully reconnected the Symo cabling to my Apogee Centaur minors (with everything unplugged at the time), then plugged in the components, and connected the power. No right channel.......................

8. Before ever taking the Adcom out of my place to get repaired, I was absolutely sure I had gone through a variety of cable switching, etc. to be assured that I didn't have a bad piece of cable and that I had not damaged my speakers. All of that seemed to test out fine.......or at least I thought it did. Needless to say, after #7 above, I started second guessing myself............

9. Yesterday, I borrowed an old, unused Denon receiver from a friend. I used some old, never-used Monster Cable to connect the receiver to the Apogees. No right channel...................

10. I guess I better start searching for help with repair of a 15-year old Apogee Centaur Minor............... or maybe it's just time to start completely over when finances permit.

Hi agingaudionut,

Did you try swapping the input leads, then the speaker leads?

I really don't like the sound of your repair. Did you get old parts back, or can you see inside where they worked on the unit? Unless they can provide details and parts, I'd have a talk with the folks at Adcom. PCB's are not available I don't think. Worst case is you paid $$$ for the amp to sit and they found there was nothing wrong with it. They had to charge you for them sitting on it for a month.

Hi Anatech,

Thanks for your note back and recommendations. I was so fed up after testing my speakers with the borrowed Denon receiver that I just turned everything off and decided just to leave it be for a while......

As regards the establishment that allegedly did the Adcom repair--- needless to say, I would never go back there. There was a lot of delay, several never-returned phone calls, no clear cut explanation regarding what was found to be wrong, no return of the replaced parts. The store owner was more interested in spouting off about some new optical cabling he had for the low, low price of $1500/metered pair. After I saw the Adcom connected to components at his store, and he played it briefly, and it seemed to work fine, and then determining that I still had no right sided sound after using a different amp/pre-amp (the Denon that I borrowed.......), I have to admit concluding that I must have toasted BOTH the amp and the right speaker. There is always the possibility of a dead right channel in the borrowed receiver and/or damaged speaker cable (I used different speaker cable with the Denon than I used with the Adcom); however, the friend from whom I borrowed it felt sure that the receiver worked fine the last time he used it, and the standard Monster cable that I used was stored, never used, and appeared to have no obvious defects on close inspection.

Some next steps will be to try to find a couple of speakers to borrow to test my Adcom equipment. I should also mention that when I tested my Apogees with the borrowed Denon receiver, I simply used the tuner as the input; however, I should go back and make some additional speaker cable switches just to make sure.

Thanks again for your notes.

Hi agingaudionut,

I was authorized Adcom service before selling my shop. I have a very deep distrust of store repairs. Their mark ups are normally well over 20% and they are more likely to mis-use a customer's trust. Always remember they are there to sell new gear, repairs are a problem. I bet they were hoping you would refuse the estimate and leave it there.

There were times that lead time exceeded a month, but we always informed the customer honestly about delays. We always returned all parts with real supportable documentation as to the nature of the repair and work performed. If I were you, I would contact Adcom about your experience as it sounds like you were abused. Request that Adcom gets back to you about who repaired your amp (outside shop?) and details. Do not leave this. Yes the amp was out of warranty, but you did take it to an Adcom dealer that they (Adcom) recommended.

This puts Adcom and the dealer at odds, but you are performing a valuable service to Adcom. They need to know what happens to an Adcom customer in the field.

Regards, Chris (another thing that makes me angry)

Hi Arif,
Thanks, but it's just my (strong) opinion. I feel this would apply to any brand.

This is what gives service shops a bad name. Many stores will double the bill. Why should they make about 4X what the shop makes?

-Chris
