C-Audio RA1000

Hi, I don't think you really need a user manual. Its a fairly standard MOSFET power amp from around 1990.

Nice features are - balanced inputs, DC/HF Speaker relay.
Soft-start PSU (goes wrong if it gets damp)
seperate rectifiers/caps for each channel.
The drivers are powered from a higher voltage supply than the output devices, giving better drive.

er... thats about it
