Re: Tektronix 465 No Trace, No Dot


The easiest thing to try is to short the V plates together & the H plates together.Don't trust the position indicators to tell you the whole story; they indicate what the amplifiers are doing, not the CRT.

I would be very nervous applying an ext filament transformer to the CRT.That filament is usually at a high negative voltage, IIRC correctly, on most scopes, it is greater than -1KV.
