Canary Audio M500, 50WPC 300B Mono Block

A Super Condition pair of Canary Audio M500 Mono blocks.  These have only been pampered in our Showroom. Very light use, so its like getting an almost factory fresh pair, but with substantial savings.
The  M500 is quite heavy (est. 250 lb. on the pallet) so the original shipping cartons will be securely palletized and shipped to you via motor freight, we have super discounted rates with our shipper so shipping anywhere in the US is negligible.
The M500 is US120V Voltage and changing voltage on these is not easy,  for international buyers a very suitable step down / isolation transformer can be supplied for a small fee.

If you want to know more about this item or any of the other cool audio gear we list on Audiogon, call our world-class showroom in Southern California at 619-440-8237 and ask for our audio/electronics expert-in-residence, Peter. 

We have extensive experience integrating the elements of sophisticated audio systems. We build complete systems from the ground up, and have in-depth working knowledge not only of the pre-amps, amps, and power supplies that support our loudspeakers but of the component synergy that makes the difference between good and great. At PBN, "great" is our everyday standard.

M500 Mono Blocks Power Amplifier Built around 300B Triode Tubes:The M500 is a class A triode mode, push-pull parallel mono blocks power amplifier with 300B output tubes. It features a modified circuitry that guarantees a more dynamic soundstage with deeper base tones. Like all other Canary products, only highest quality parts and components are used in critical applications. The oversize custom wound power and output transformers are specially designed to handle twice of its power rating, ensuring durability. Two independent chokes are employed for rectifier filtering on each channel. The Muscular Canary:The M500 mono blocks power amplifier is specially designed for optimum sound quality. Deliver high power music at wide dynamic range with ultra low distortion, the M500 is simply the finest amplifier one could desire. Maybe the muscular canary doesn't exist in nature, but if one existed, it might sound something like this amplifier. 
Special Features: 

Newly designed high voltage power supply.

Rectifier with double choke filtering (two chokes are employed per channel).

The input circuit has been redesigned to be faster and more dynamic.

Custom EI power transformers.

Exclusive machined Delrin 300B tube sockets with gold plated pin receptacles.

Bias LEDs for easy and precise adjustment.
