I picked up a barely working Orion HCCA 225 Digital Reference on a trade and it has extremely low output.
Thus far I've checked the SMP60N06-18s in the Power supply section as well as the 2n6491s and the 2n6488s and nothing appears to be shorted or open. Rail voltage is where I think it should be at 22.5 volts.
I guess I am off to troubleshoot the audio section next but I did have a couple of questions. What are the chances that there are bad capacitors blocking the audio signal from passing through the amp? Also, if I decide to replace the SMP60N06-18s, would the IRF3205 be a viable substitute?
