No luck eh? Just picked one up. Film caps, through hole.
All I know, third order filters. DC to DC converter. I am sure it looks like about any two way crossover that has a grand total of 6 op amps in it. State variable I would guess as it has switches for frequency. Going to plop on some newer op-amps.
Sweet little box.
