OK on the PS & MOD comments. Understood. But that's not a big problem. Would be nice to have the dynamoter / modulator but a reguular PS going to AC mains will be my approach. I like the idea of having the TA12 in my Crown VIC as a mobile. Just need a receiver to go with it and a small AC generator to tow behind.
My plan is to use a couple of 1625's as modulators with fils wired in series so they can be hooked up to the 24 volt supply that will be needed unless all the fils are rewired. I'll have to have the modulator configured to have ear splitting, yellowey audio to simulate a military transmitter so I can check into the Military Net Saturday morning and not get kicked off
Interesting that the 12SK7 fils are wired the same way with chan 1 & 2 fils in series and chan 3 & 4 wired in series. Come to think of it - it might be a good idea to rewire the fils for 12 volts. That way, I can just hook the TA12 up to the car batt.
I stumbled across an excellent source for the manuals.
http://www.vmarsmanuals.co.uk/archive/files_index.htmOne is the service manual that includes disassembly instructions. I don't think the lack of IPA and PA metering is a problem - A regular DC milliamp meter can be put in a box and just plugged into the TA12 during tuneup. The rest of the time the RF ammeter will tell the story.
