Roger,

The deflection circuitry is quite different in the Teletone 149 than in my Admiral set with the same CRT. The Teletone (and your set) has very straightforward oscillators and para-phase amplifiers, so it should be easy to get the deflection working well.

Also unlike the Admiral, the Teletone is a hot chassis set, so best to run it from an isolating transformer and ground its chassis before attaching test instruments to it, but don't forget the isolating transformer defeats your dwelling's breaker box RCD.

Hugo.
