Hello, everyone.
I am still looking for a Schematic for the Hitachi HA6800 Mosfet
Amp that I am repairing.
Can Anyone help me with this?
Thanks.

Hi Telnet100,

I also just acquired a working HA-6800.

Do you still need values of burnt resistors?

Default Hitachi HA6800 Mosfet Amp

Hello, Poetry2me.
Thank you very much for your Kind reply, after such a long time!
Since then, I have managed to obtain a schematic, which I then used to
rebuild the rest of the Amp, which now works well as intended.
This is a good amp, probably due to those lateral Mosfets in the output
stage, and does really sound nice.
I have since managed to obtain a Full Service Manual for the HA6800, which I will send to anyone who wants a copy, as after all, that's why we are all on this forum!

Thank You Once again, and Have a Good Day!

Hitachi HA 6800

Hello Telnet100,
I'm using the Hitachi as a PA amplifier. Bought it for only 1 Euro on a fair! Works fine, nice sound. When overloaded it stops functioning to cool down. Like to have a schematic. Can you sent me one?

Thanks,
Pete33
