I am a one man shop, with 30 years as a electronic tech, so each piece of high quality audio equipment gets my personal attention, of which I repair, clean, adjust, and inspect everything as if I were keeping for my own. I have personally been completely through the internals of this 555 II power amp, insuring everything is to factory specs. I leave no stone unturned. So you can buy with confidence knowing you are going to receive a very high quality amplifier in perfect condition electronically. This unit (after initial check out on a Sencore PA-81 analyzer) has undergone hours of testing under load, driven by a Carver CD TL3200 music source, into a Harman Kardon 825 pre-amp and pair of Paradigm Esprit B/P 8 ohm 300 w Towers. PLEASE NOTE: When I refurbish a amplifier, I don’t just repair the problem and sell it. I completely disassemble it, meticulously clean everything, (just check the pictures) then I use Deoxit D-5 ® on all connections that needs this process. I make the internals better than new, so that you will have many-many years (min 25) of enjoyment from your new amp, without component failure or component degradation. (Excluding) shorted speaker wires, inferior speakers that can’t handle the power, or turning up the volume to the degree that you can fry eggs on the rear heat sinks. Or blow the windows out in your house. :-) All four electrolytic’s 47uf @160wvdc have been replaced with new Nichicon electrolytic capacitors upgraded to 100 uF 160 wvdc audio grade on the power output PCB’s. Also 4 .I uF 400 polypropylene caps were installed in parallel with the bypass caps.The driver bias voltage was adjusted to 9.5 mV per side.The driver transistors 4 each were upgraded with a higher break down voltage for more headroom.The rail caps have been tested as follows:C1 rated at 15,000 uF and allowable 9,000 uA leakage.
