Title: EII power supply schematics?
Post by: Mender on April 05, 2011, 10:37:06 AM
Are schematics available for the Emulator II power supply?  The service manual does not contain them.  It was oem from Compower and circuitry not revealed by Emu.  The unit I am working on will not boot when cold, voltages are way low, and the transformer is clicking rapidly.  Problem wire harness connections were bypassed and resoldered first thing.  Unit works fine at room temperature.

The service manual I have contains a schematic for the PSU, which is drawn by hand.
It can also be downloaded from the Files section on the Emulator II Yahoo group, but if you are not a member yet, just drop me a personal message with your e-mail address and I'll send it to you - you shouldn't apply for membership just to download one file, we try to avoid that  ;) )
