Hi Guys I'm down under in Australia, and have 2 of the MTV1's I have one working but has poor RF, from what I read it's caused by the vari-cap diodes in the tuners (s), I had to replace the vertical transistors (4 off) to get frame deflection, the other one has a few damaged edge connector pins, and I have no idea where to get them, it also has a faulty ST3-01-03 IC, incredibly my brother has located some in UK and 2 are on their way to me, it would be nice to get a good quality copy of the circuit, the one I have is quite poor, cheers John.
