Default Re: GEC BRT400 receiver.

I have one.

As has already been mentioned, the unconventional power supply arrangement is a big problem - on the receiver I have the original transformer had already been replaced by a real mess of transformers and bodgery.

I ended up rebuilding the PSU with a different transformer, and conventional smoothing, I took advantage of my transformer having a HT voltage that was far too high, and floating the centre tap above ground via a string of power resistors to give me a bias supply for the rest of the receiver.

I have to say, it is a delight to use, and well worth all the hard work repairing it - the hefty output stage and well designed RF bits really make broadcast listening a pleasure.
