Post subject:  Classe DR-8 in need of repairs

Since Classe audio has gone under, does anyone know of a service outfit in Calgary that would repair my DR-8?
Needs recapping.

Thanks in advance.

ps. My apologies if my searches missed an answer.

Classe has not gone under. Was acquired by Sound United earlier this year. Don’t know if they can or will repair an amplifier of that age, but worth contacting them.

Thanks for the update , sthomas1049.

Is there a 3rd party repair option in preferably western Canada ? Otherwise, it's a boat anchor.

As Classe still exists in Montreal and is promising continued support on legacy products, you might want to ask a local Marantz or Denon dealer if they can send the unit in for service, as they're all part of the same Sound United family now.

There was another thread dealing with a Mark Levinson vs. Bryston amp where I posted this link to an article about Classe but that thread seems to have disappeared.

You can try Tom @ Apollo Electronics: http://www.apolloelectronicsltd.ca/

I think the biggest challenge you could run into is parts availability if the output transistors turn out to be dead; Classe would have originally sorted through large quantities to match them closely. Some of the older Classe models as as yours didn't have very good documentation from the factory (such as a parts list) and the part numbers were typically removed from the devices in each amp. Unless the "new" Classe has managed to recruit their old service team (who was let go earlier this year by B&W) there is little chance one of the other service departments under the new ownership will be able to assist. I dealt with the old service team directly on a couple of occasions, and they were of great help due entirely because of their memories and years of direct experience rather than anything written down.

If the unit is good and broken please let me know as I would be interested in it for parts (a local CAM buddy has a pair we'd like to keep running).

EDIT: I see you just want it recapped...Tom could definitely do that for you.

Yup, find a good local technician.
Dave Reich sold Classe decades ago. The people running it after that couldn't build an amp as good as the DR8 if their lives depended on it! :roll: :lol:

Classe' service was excellent. I can't say what it's like now. I'd take my time and find someone to fix it. I know of one or two here in my neck of the woods but that doesn't do you a lot of good in Alberta.
I'm not sure about the DR-8 but the Ten came with a LIFETIME warranty to the original owner.
In any event I'd give Classe' a call. What have you got to lose?

Hi, depends what work involved with your DR-8.
If you want it to be to the original at best condition, that is with the original type of power caps, then Classé I hope would help you.
I did not call them here actually, I was in need to have bias current info for my Classé , but I guess it was in the time they were announced to be closing!?
So you may try now to call them to see.....

A very good tech may carry some upgrades and caps replacements and bias adjustment.
To give you an idea a good friend sent his DR-8 years ago, It came back with new filter caps, bias, etc.
Cost him a good $900+ if I remember well.
Thing is the original red filter big caps are very expensive are a specific Classé type.
We did search for exact one, none to be found and they are not computer grades, they are switching type as I remember.
OK
you may replace the one actual with computer grades ones, nothing will blow, it's just that the Classé sonic signature may not be met??
Bias point is not reveal, you have to search for it, but it may bring heatsinks near 40 deg Cel once all settle ( 2-4 hrs)
Good Luck.

Thank you, all for your comments and recommendations. Since I am an original owner, I will investigate my warranty options with Sound United
and keep this DR-8 performing another few years.

I had my DR-3 serviced recently here in Toronto at of all places...The Speaker Shop (quick turnaround and and a reasonable bill). Output transistors, biasing, can't recall if caps were replaced. They were of the opinion that while it was a a great circuit design utilizing high quality parts, there was nothing exotic or complicated about it.

I sent a message to the new Classe service email address yesterday. They advised that all service work now and going forward will be done in Syracuse, New York. Looking at the address they provided, I see it's not actually Classe, but a third party called United Radio. I asked specifically if there was any expertise from the original Classe repair team, and they said the New York team had received training from them. I'm a little skeptical how the new team could possibly become familiar with the myriad of legacy models. Also shipping a heavy amplifier out of country obviously will add significant cost and border challenges.

Here's the list of products that United Radio services: http://www.unitedradio.com/consumer-ele ... udiovideo/

There are some excellent service outfits out west. I wish I could remember their names. Commercial Electronics (?) comes to mind for one.

I think you would be best served by a good audio technician in your area. He will likely be in his 50's or 60's and work from home or an old (long established) shop that does audio repairs. TV guys generally don't service audio well, I don't service TVs well for example.

You don't need the original output transistors either. Some of the current ones are superior to the ones made in the last century.
