Hi group. I bought one of these and found service manual online. The book describes the model I have, however, the schematics on the last four pages are for a model that has a rotary switch with six positions as well as a potentiometer for pulse delay. Mine does not have that, it has only a potentiometer for delay.? All the references on the schematic for resistors, parts and ICs do not match my unit.
I will shotgun the ICs and replace the ones I think are bad to get it to work. Anyone have a manual for this unit? Hutch
