DEC Terminals, free P/U in CA

I've head the VR241 called a lot of things, most of which are not repeatable here. It's a Hitachi chassis, and uses similar circuity to their TV sets of the same period. In particular, the vertical deflection circuitry (and IIRC the horixzotnal oscillator) are on a thick-flim hybrid circuit in the middle of the deflection PCB. This is not identtical to the ones used in TVs (at least not UK TVs), so they will not do as spares. Some faults can be fixed, but sometimes you have to kludge things rather more than I like Secondly, the PSU is odd. It is driven by the horizontal deflection oscillator, there's am extra winding o nthe flyback transformer that is actually conencted ot the mains side of the PSU circuity (so technically the flyback transformer bridges the isoaltion barrier). Of course the horizontal oscillator only runs once the PSU has got going, so there's a startup multivibrator on the PSU board that is disabled when a capacitor has charged. Therefore, for the PUS to start up and keep running not only must all the components on the PSU be good, but aloo that thich-film module, the horizontal outptu transistor, the flyback, etc. In other words just about all the parts that normally cause problesm. So fualt tracing is a lot harder than on some other monitors. -tony
