Great info Nigel!!! I will go ahead and try to get the necessary voltages with external supplies to see if the mother board is functional then if so, I will try to fix/rebuild the PSU module.

The Voltage Converter Assembly appears to be bad. Not yet sure if it got the mother board also. Are there schematics out there, and can you get replacement parts for the DC to DC converter package. I have searched the K8CU pages and of course have the user manual. Would it be possible to supply the 5/15/-15 volts from and external supply or would that have an adverse effect on the performance of the oven and oscillator. ------------------------ Hi Connie I'm sorry to hear your bad news, let's hope it didn't get the motherboard too:-( I've been looking for a spare PSU module for quite a while now without success. I did think of just building a separate PSU but was a bit wary as the outer oven controller is on the power module and I wasn't sure what that involved. However, I recently came across this web page, which you might find useful... _http://homepage.sunrise.ch/mysunrise/shegnauer/Z3801A/Power%20Supply/z3801a _p ower_supply.htm_ (http://homepage.sunrise.ch/mysunrise/shegnauer/Z3801A/Power%20Supply/z3801a _power_supply.htm) regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
