Amp repair...What to expect.

Mine took 50 hrs. to start sounding like a Sunfire again. Then at about 300 hours, it opened up and sounded like its old self (except that now it was dead-quiet).

I like the DYI spirit in several of the posts.

Just last month I got tired of dropouts on my two Sherbourn 5/1500A monoblock construction amps, chatted with a friendly tech, ordered $2.50 relays, and using my Xtronic solder gun and air tool workstation, some desoldering wick, and high silver content solder, i replaced all 10 relays.

In the process i removed all connector harnesses and applied electrical contact paste to these and the terminals, dusted the heatsinks.

I have been making sweet eyes at Pass Labs and Classé monoblocks for a while, but the 4 of them would be hard to justify (CP-700 biamps) now with perfect Sherbourns.

To Marakanetz and other Sunfire owners...

This is an interesting find, but price is too high:

I've seen that, but there are much better options here at 'gon for $700.

For those who's not technical, I'd say that it's still a bargain even if you will have to send the unit back-fourth to/from WestCoast to service it.
They sound like class A more than class A/AB/B and they never run hot with plenty of power to drive any speaker and SILENT when no music no matter if you mute or unmute your preamp.

Marakanetz, that's the model I have. The reason I posted it was cause it's a rare find with those low hours.

But yeah, the smart thing to do is but one for $700 and sent it to Roland out west.
