I should know better but............in cleaning out the transformer bin in the shop I found a Thordarson 6699, which looks to be a medium power mod transformer marked P/B/P on one side and C/500/3500/6250 on the other. Does anyone have specs on this puppy, or a rule of thumb I could use to figure out approximate power it can handle?
What I'd like to build up is a simple 2 (final) tube modulator modulating a simple class C final, with a common power supply voltage and somewhere between 150 and 300 watts output of fully modulated AM. My neighbors haven't voted yet. Can anyone recommend a favorite set up that fits these numbers? I'll admit to being a bit lazy and not having done the math yet, but thought I'd ask first - it would be too good to be true for a pair of 811's modulating a 4-125 or an 813 to work, I imagine. Any suggestions greatly appreciated. And is there any problem with running a mod transformer at 1/3 or so of its rated power, other than having to lift it :)? Also I picked up some other Thordarson chokes and xfrmers only having Thordarson numbers on them - I naively assumed someone might have a web site up with that type of info - did I miss it?
