M-500 MARK II Manual Addendum

The M-500 is widely considered the most musical of Carver's M series amplifiers. Billed as the Light Heavyweight, I've always hoped to have one with more power. Nine months ago I started experimenting, and the Carver Mk II modification upgrade is the result. Each amplifier goes through a 2 track process.

TRAC I

Troubleshoot:	Component level fault isolation.
Repair:	Replace any malfunctioning parts; bring the amplifier to working status.
Align:	Perform all published alignment and service bulletins.
Calibrate:	Verify performance against published specifications.

TRAC II

Test:	Check power diodes and resistors for drift in value due to age and use. Perform initial benchmark
Restore:	Replace all electrolytic capacitors; power resistors and power diodes replaced as required
Augment:	Replace all voltage rectifiers with higher current devices. Boost power supply rail voltages. Re-design gain stage for new rail voltages. Replace all electrolytic capacitors and pre-drivers with higher voltage/current devices. Increase capacitance from 31000 uf to 44000 uf. Replace output transistors with higher current devices using 7% silver solder.
Calibrate:	Benchmark to new specifications. Perform 96 hour burn in at 1/3 power into 4 ohms. Final alignment.

The result is an amplifier with a much higher power rating, more headroom, less commutation distortion, better current sourcing and performance into low impedance loads, as well as tighter bass and transient control.

Bonus upgrades:

5-way binding posts bring the amp into the 21st Century using 7% silver solder
Meter incandescent lamps are replaced with high output LEDs of your color choice
New High Grade Output relay
Modern silicone thermal isolators are used in lieu of mica and paste

What can I do with it?

The M-500 MK II is an awesome 2 channel amplifier

For home theater use, it can be used to power the front left and right speakers by connecting the amplifier to the HT receiver preamp outputs. If your HT receiver has no preamp outputs a line level converter may be used (I can make one for you if required).

What happens if the amp fails?

During the first 15 days, if you are unsatisfied, for any reason, with the M-500 Mk II you can return it to me and I will buy it back for the sale price + $50.00.

As long as we're alive we will repair any M-500 Mk II sold for cost of parts plus shipping.
