Parasound HCA 3500 John Curl Design Class A / AB Amplifier Dual Mono Near Mint

This amp is a monster, 85 lb beast but the beauty lies in the sound with pure class "A" output for the first 15 watts. This is a true dual mono design with 2 power cables and switches, designed by the famed John Curl. These don't come up for sale too often, now's your chance. I prefer Paypal but will accept a postal money order as well. No manual or original shipping box but I'll pack this extremely well, double boxed and ship it fully insured via Fedex. Price includes shipping (lower 48 only) and all seller's fees, thanks.
