Gentlemen,

Thank you very much. I was indeed wondering about that particular issue of the watchdog IC. 5.1 Volts DC it is!

Just on the Acopian Power Supply, in case anyone here is interested, I bought my new 250 Volt supply from a US eBay seller who got these boxes from a local Areospace company sale. The two units he has (both are 3V51212T11A which is the 120 Watt, overvoltage protected, version) retail from Acopian for $US600 each and I offered this seller $US65 which he accepted. Yes, I said $US65! I couldn't resist despite the fact that my first preference would've been to have used a FG Tektronik NMC 105 supply internally.

In case anyone is interested, this seller has one more Acopian PSU remaining.

The price is a huge bargain. Hope someone here can make use of it.

Thanks again everyone for all your help. I'm indebted

Tas
