I have the schematic on microfiche. Did you have a particular problem or
question you'd like to share with the group?

**There are few problems with the 1070 that cannot be solved easily. If the
relay is a milky white type (rather than clear plastic), replace it. It is a
cause of channel dropouts. If both channels are out, check regulated power
supply (simple zener, series pass arrangement). There should be 41 Volts DC
(Check ripple) at J810. That's pretty much it. Output stage failures are
very rare. If one has failed, don't forget to check Emitter resistors.
