Don't need to remember, I have two such sets (both much older than me) ;-)
I see...
I doubt there are many such sets still in use over here. They'd be Systam
A (405 line) which means they'd need a converter to use with Systme I
signals (or the outptu of a digital TV receiver). Oh well...
Incidentalyl, when I looked at those CRT data sheets yesterday, the same
book contains recomended circuits for 'high defintion TV timebases'.
That's 405 line 'high defintion' of coruse :-)
