Question on a Levinson 27.5 amp

Kowkow, please forgive me if you already did this, but did you check the fuse on the "dead" channel?

No worries mate, first thing I checked indeed.
Would be reasonable isn't it to have blown a fuse.
But sadly, not so easy. :(

Kowkow,

Not sure on the cost for #27, but Harman (Industries?) who owns the Levinson brand quoted me $1200 USD flat rate to fix/refurbish my #23.

There is nothing wrong with my #23 that I know of, but I contacted them about getting a factory check-up/tune up and that is what they said for price. The price includes all parts/adjustments to bring the amp back to completely like new performance. I thought it was a little steep just for a tune-up/check-up since mine seems to be working fine.

Whoaru99, if your amp is "working OK" but you just want to see if it's performance is "up to snuff", just take it to any local audio technician and have him put it on his signal generator and he'll check the output on his ocilloscope. He can tell you many things from this simple test. And that's probably what Levinson would do anyway, at least to start with.

anyone know how to convert to 220 volt?
