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!

Nelion Audio started following Carver C-9 Restore
-
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.

Nelion Audio started following pm 1.5 fan motor, Resistor question., Carver C-500 restoration and 3 others
-
@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!

FYI - we do have some OEM fan motors now. Please contact us if you need a new motor for the PM-1.5.

The A Series Carver Amplifiers were late in Carver's Production years. Although not Magnetic Field Coil amplifiers, they still inherited many of Bob's amplifier topologies that create an accurate, musical and powerful sound reproduction. Although the extent to which Bob was involved in the A series design is not known, it is unmistakably an extension of his earlier designs. The A-series amps utilize voltage rail switching to produce immense dynamic power without having to add cumbersome heat sinks. The high voltage rails are engaged by Power MOSFETS which modulate to the output signal and
