Canary Audio CA-300 Refurbished at factory

Selling my CANARY AUDIO CA-300 SINLGE-ENDED MONO BLOCKS. I have owned these since 2011 and taken care of them since. I had rescued them from someone and took them back to the factory for a full refresh and have enjoyed them sparingly since. If you know Canary you know these things are built like tanks. Some minor scuffing I would give them an 8/10 on the Audiogon scale considering age and that they have been refurbished. I have moved on to other amplifiers hence the sale. Buyer is more than welcome to audition before purchase. Tubes included and have plenty of life. Willing to deliver within 200 miles of the SF Bay Area. 3% PayPal fee applies as well as shipping charges as they are heavy items.
