Greetings... I'm got a partially faultly Sirius (aka Victor 9000?) on the bench at the moment, and it appears to have (at least) a sound fault. Alas there are 2 chips in the sound circuitry that I can't find any data on : Harris CI55516-9 (16 pin DIL, maybe a codec or similar) Spague (?) ULN3701Z (5 pin TO220, audio amplifier).
