Hitachi HMA-8500 Mk II rated 100 watts per channel into 8?, 35.2 lbs./16 kg A classic vintage MOSFET class AB stereo power amplifier with extremely low distortion. 20~20,000 Hz at 0.005% THD or 1 kHz at 4? or 8? at 0.005% THD. Its a real dual-mono deign. It even has two power transformers as well as two sets of power supply rectifiers and capacitors. Each transformer has its own input voltage selector! Ive owned them for over 10 yrs. They work great. The caps are original and as far as I know never replaced. Sometimes the VU meter on one wants to stick and unstick. Doesnt all the time. The sound is audiophilic. I have used them in mono form and that is the best. MOSFET sounds natural and I like it more than solid state. This is a very rare amp and its hard finding just one now but here is two! For audiophiles as me they are one of the best vintage amps you can get your hands on. They are a little dusty but in excellent cosmetic shape almost perfect. The white marks are dust and not a cosmetic damage at all. They look dark in their natural new state. I should have wiped it off for the pics. Shipping is flat rate to the US and Canada excluding Alaska, Hawaii. Europe rates please inquire. Theyre super heavy. Will be packaged well.

THESE MUTHAS ROCK! I have to fix my truck or I would keep them. I have them hooked up to my Yamaha home theater. My Yamaha receiver is a 9.2 with plenty of power but Im a drummer so my hearing has some challenges and these have been a blessing with the dial hardly turned up. They even have the original Japanese plug ends on them with US adapters. Ive taken good care of them and the kids have NEVER had their sticky hands anywhere near them. They are sweeeet! Thank you!

Hitachi HMA-7500MKII Stereo Power Amplifier. 75WPC. Tested, works fine. Original owner. Acquired roughly 1983. VG condition. Model # conflict. Front panel says HMA-8500. Rear panel says HMA-7500 MK.II Was originally represented as HMA-8500. Probably 7500. Beast of an amplifier. Beautiful VU meters.

Vintage Hitachi HMA 8500 MKII Class AB Mosfet Stereo Amplifier. Im the original owner and the unit works flawlessly . The amp is very powerful and very clean sounding. In lower volumes it runs in Class A mode. Large VU meters still function just fine. This is a 120V unit.

SMPTE Intermodulation Distortion0.005% at 50 W.The Hitachi HMA-8500 Mk II is a high quality 100 watts-per-channel MOSFET class AB stereo power amplifier. MOSFETs are solid-state devices that work on principals more similar to vacuum tubes than bipolar transistors — and it sounds great!Its a real dual-mono deign. It even has two power transformers as well as two sets of power supply rectifiers and capacitors. Circuit DesignIts a traditional class AB linear power amplifier in a perforated sheet metal steel case.It runs hot; its biased for class A most of the time. Hitachi discovered a source of distortion was varying capacitance of the output devices near turn-off, so by biasing them more towards class A they eliminated this extra source of distortionThe power rails run at ± 58 VDC.There are two 6800 µF 63 VDC caps and one 1 µF 250v Mylar per rail per channel, total 12 caps and power supply four rails (each channel has independent supplies).There are two pairs of 2SK134 and 2SJ49 in parallel for each channel.The meters are fed from the headphone feed. The headphones are fed from the speaker rails (before the speaker relays) through 333-1/3 ohm series resistors.The protection relay comes before the headphone takeoff. The protection relay waits 5-10 seconds at turn-on, and also trips if there is too mu DC at the outputs.The meters use a semi-peak half wave detector and drive the needles which have VU ballistics. I do not offer returns due to high cost of shipping back and for , the risk of damage. This unit works flawlessly. You would be impressed with the sound quality of this unit.
