Re: Can you identify these boards ?
The Telpro version always seemed to have really bad IF instability for some reason. I imagine they were easier to service but never gave the picture a Bradford did. Seems a bit of a pointless exercise, though I admit changing the LOPT, tripler or the surge limiter was easier. Mind you, they could just have made the surge limiter a bit bigger...
They also did the same with the mono 2020 series, using big transformers and chokes instead of the droppers, with a completely redesigned layout. They were usually badged 'Telefusion'. In both cases I regarded them as useful donor chassis.
