Is this typical Service?

Mapleleafs3-the amp has what I think is a loud hum.Noticeable standing a few feet away,it doesn't come through the speakers. Usually with amps of this vintage its a power capacitor that causes it.A sign of age. While the amp is working I'm afraid that (a)the problem will worsen and (b)when it fails out right it may cause severe damage not only to the amp itself but to the speakers also.
Now for the good news -Classe will provide a proper box and honour the warranty provided the proper receipts and arrangements have been made with their service center.
This applies to everyone not just my self.
I want to very clear on thus topic. I was not trying to weasel out a freebie.I have a legit worry that there is something wrong with the amp. I felt Classe's orignal position to be somewhat harsh, fortunatly the powers that be changed their policy.
Classe' deserves a pat on the back for their change of heart.I'm going to stick with them.I bought the Classe' Ten amp because at that time (1993) and for that amount of money IMHO it was superior sounding to anything near its price. I didn't regret buying it then and I don't regret hanging on to it now.
That said,I stand by my advice SAVE THE BOXES.I would have saved my self a couple headaches had I known.And consider Classe' for your next audio purchase.They care.

You mentioned the hum coming from the amp and not the speakers, you may want to pop the top and tighten the nut and bolt holding the power supply as I own two of there 25 amps and I noticed one of them having a slight hum. I gave the nut and bolt holding the power supply a slight tightning and no more hum. One other thing is excesive DC on the line as this causes hum in the transformers. Maybe worth checking into before you send it off. If you go to psaudio.com they have great info on hum and what causes it.

$75 and hour charge is reasonable - and pretty consistent with what I've experienced with other companies. In my experience, the minimum service charge is 1 hour which I think it fair. 4 hours minimum to check them out seems really high - especially if nothing is wrong. Did I misunderstand you? In other words, they told you that it will cost at least $300 each, $600 total to check them out. Something is wrong there.

I just sent one of my M200's back to B&K to check out an intermittent fault - it cost me $96 including labor (1 hour which is the minimum), parts - one part bad (a switch) and few other minor parts they replaced to bring them back up to Spec, packaging in a brand new factory box, and shipping cost back to me.

Daveherm69: Since their purchase by B&W about 4-5 yrs ago, Classe is no longer a "CDN company" as you say...for true CDN stuff, check Anthem, Linar, Bryston....Classe is now a big international company and their warranty policy may not be as easy-going as it used to be. On the other hand, you can tell by their new products that the cash influx from B&W made them move up the ladder. Quality ladder I don't know but the look and price sure have moved up!

Beheme is quite right, Classe' is now an international company.Still they showed amazing concern that we work out our issues. I do have to wonder how on earth Classe' ever got the nerve to offer a life time warranty way back then. I'm glad they did though.
Regarding service time,Classe' stated their technicians are very meticulous and it would take a minimum of 4hrs.per unit.
I also inquired about having some gain added to the m/c section they said it could be done at a cost that probably wouldn't exceed $100US.
