This Amp was made By John Curl when he was with Wangine before he left and made Parasound. The last example I believe went for $1700.00 with that data provided by Worthpoint. I am just looking to get back what I have paid for it. Thanks for looking!!! This amp is 100 lbs. That is why the shipping is so high.

PARASOUND HCA-3500. 40kgDesigned by John Curl JOHN CURL and is built using only the finest precision components available for optimum musical quality and performance. for sale power amplifier PARASOUND HCA HIGH CURRENT AMPLIFIER 3500 single owner model, a beast of power also a true dual mono so it is as if it were two mono amplifiers with separate power supplies and therefore two power outlets 350wpch 8ohm channel and 500wpch 4ohm channel manages difficult loads up to at 1 ohm even if it is not rated power supply consisting of two 1.4Kva toroidal transofmers ,one for each channel and then the power of power supply is 2800watt = 2,8Kva 97,600 uF supply capacitance for each channel The direct coupled design uses no inductors or capacitors in the signal path Class A Cascode input stages with matched J-FET pairs Hand-picked complementary MOSFET transistors in the high-voltage driver stage the first 15 watts for chanel are in pure class A and then class AB beautiful and powerful power amp for international shipping, contact first but I can ship throughout Europe on a pallet platform, but contact first to precisely agree on the shipping price depending on the country Im selling because Im not using it
