Thanks Bruce. Actually the +15VDC is the oven supply and the +24VDC is the electronics supply, kindof surprised me!

However if you do this you may well need to replace the foam plastic (urethane?) insulation used in addition to the vaccum insulated flask. Bruce

Or you could just connect the 24V supply and see if you get the clock out, and vice versa. This is certainly a lot easier and less destructive than taking the thing apart to find out which supply is which surely. > Bruce > > _______________________________________________ > time-nuts mailing list -- time-nuts@febo.com > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. > -- Steve Rooke - ZL3TUV & G8KVD & JAKDTTNW Omnium finis imminet

In the absence of specifications, some details of the circuitry are required to get some idea of the power supply limits. Bruce

Well, IMHO, it's not worth the risk of opening the thing up instead of just putting in a regulator to supply the heater. 73, Steve -- Steve Rooke - ZL3TUV & G8KVD & JAKDTTNW Omnium finis imminet
