Audio Research HD 220

Freind of mine sent me his HD220 for repair - Blown rectifier was the issue - it had blown the inrush current limiters. Got the Bridge replaced and the amplifier powers up - it however never release the soft start, Ie close the large really to short out the resistor inrush current limiter series connection (which I replaced with a large 12A one)

The indicator LEDs on the face does not illuminate nor does the amplifier unmute. Anyone with a service manual for this on - could not find anything on a search ora none with any experience with these ?

Any input greatly appreciated
