Now, I have a 4.7uF cap in the recap kit, but looking at my stocks of resistors from other projects I don’t have a 270R. I do have a 240R or 330R. Would either of these be ok, or do I really have to resort to ordering a few off evilbay???A significant cause of problems has been found to be failure of the internal power supply
transistor TR4. The circuit may be improved by changing the value of R60 from 100R to 270R and
connecting a 4.7uF electrolytic (preferably radial type) with positive end to TR5 emitter (positive
end of C34) and negative end to TR5 base (to R58).
In better news looks like the machine code mod and the video quality mod mentioned were done at the factory, which is good
