Sure looks like Syncroguide to me.

Here are a few possibilities.
Flyback is bad or hooked up wrong - Check your wring and check the resistance between flyback windings. Should be close to values shown on scheamtic

Horizontal oscillator running way off frequency. Check waveform on pin 5 if you have a scope.
Weak drive signal to 6BQ6 - Does adjusting the horizontal drive do anything ? Check DC voltages on 6BQ6 too.
