Hello @Kevin L, Welcome to Nelion Audio! Please email us at service@nelionaudio.com to work out details for scheduling. We can make your M1.5t sound better than ever. And as for the power, you can never have too much. It's all a matter of knowing what your speakers, your room, and your ears can handle. Any amplifier has the potential to blow a speaker, so really, blowing speakers is more so a user error than because of max power output of the amplifier. Using in-line fuses at the speakers is a easy solution to protecting them against accidental over-driving, or various ot

That looks great! Wow!

Hello, Yes, I can work on the Parasound HCA-2200II. Please contact us at Service@nelionaudio.com for more details. Thank you!

Hello, Yes we need to schedule you in. Please contact us at Service@nelionaudio.com Thank you!

Yes indeed - that is repairable.

We use OPA2134. However the pinouts are quite different, so you have to use an adaptor.

@Mike16w Oh no! Well, we can certainly take care of it. Hit us up at Service@nelionaudio.com! Or go to the homepage and hit the Contact Service button on the right sidebar.

@Mike16w Please use 0.47ohm 2W resistors. Good luck with the restore!

Changed Price to 350

Are you using them bridged?

Hello, I can restore the C-500. They are very similar to a Phase Linear 700 - brute force linear power supply and gobs of output transistors. Restoration includes cleaning inside and out, replacement of consumable parts, upgraded components where appropriate, calibration and testing. 3 year parts and labor warranty. $400 + shipping.

Thanks @RobA! Welcome to the forums!

Thanks Marc!

Hey @Bobby1970! Welcome!

The Matsushita's are obsolete. These two relays are direct crossovers: Panasonic JC2AJ-B-DC24V OMRON G4W-2212P-US-TV5 That's all I've found so far. The relay specs are: 24VDC coil, 7A contact, 2 Form A, PCB mount Mouser and Digikey never seem to provide any crossover information. It's a shame.
