Default Re: The Mongrel Valve NBTV

The result of syncing the line is below not to bad when it behaves, but i have to adjust oscillators line frequency control close to the 400hz line frequency before it locks ..

I first tried this NBTV sync separator but it didn't seem to work so switched to the one in the last post .

I am at the moment working on the deflection amplifiers using the circuit in the scope schematic or half of it at the moment with the signal input ,my understanding is its a push pull but to me it looks to me like its amplified sawtooth is to one set of deflection plates and the other is just voltage adjusted to move the display either side ? any case the one triode side amplified saw tooth side of the circuit works .

i have a made a few monitors all transistor ic jobs so i am a bit of newy here learning to do it all again from scratch
