We proudly present the official M1.0t mkII opt002 upgrade!
This mod gives your 1.0t a much higher power rating, more headroom, less commutation distortion, better current sourcing and performance into low impedance loads, and tighter bass and transient control. This mod includes replacement of all consumable parts, reflow of questionable solder, the thump fix, all service bulletins, new 5-way binding posts, cleaning inside and out. Amp is burnt-in and thoroughly tested against factory specs, and upgraded specs.
This mod has been performed by Richard Pecoraro and Greg Garska of carvermk2.com for years (since 2008) and has proven to be one of the most powerful, musical, and reliable Carver amps around. Do not trust Ebay copycat 'techs' - we are the only authorized techs that perform this sophisticated upgrade and stand behind it. All the services, kits and retro-fit boards found on Ebay were stolen and used without permission. For all of the work and improvements done, this is by far one of the best deals in the industry.
Includes a 3-year warranty and lifetime waiver of bench fees.

The original bias network (black) allows the bias point to drift as temperature increases. Addition of a complimentary transistor and network (red) counteracts this drift, and maintains the bias set point. As a result, heatsink temperatures are reduced by 10 degrees F.
M-1.0t MARK II Manual Addendum
The M-1.0t has to be one of the most under-rated amplifiers of all time. It's rumored that this was done to fit the m-1.0t in the model line (0.5, 1.0, 1.5 and 4.0). It's also suggested that it was rated at 200W to match the Conrad Johnson Premier V rating (the $12,000 tube amplifier it was transfer function modified to sound like).
This is the amp that won the famous Stereophile Magazine Carver Amp challenge.

Professionally made retro-fit boards:
(Opt002 board - designed for high current capacity)
(High Rail capacitor board. Unlike the hobbyist PCB that lays flat against the PCB on Ebay, this board does not interfere with the sensitive components on the main PCB and keeps the capacitors elevated for much better thermal cycling and electrical isolation. This board option also reduces the over-all noisefloor of the amplifier.)
(Thump fix board. Designed with hi-tech components on a sleek unobstursive PCB)
(Bias Pivot PCB designed for maximum thermal reliance.)
New Speaker Binding Posts:
IEC socket option:
Cost: $450.00 + shipping
Add the optional LED upgrade with your choice of color for an additional: $40.00
Add an IEC (C14) socket for an additional: $40
