Hi ,
Last weekend I got a beautiful Marconi TF995 B/5 from the Hack Green Hangar sales.

Changed a few poor esr caps and it works... but the waveform is of repeating three levels.
see att image.

I need help with this.

Does anyone have the schematic for the B/5. I have the A/2 but it's so different.

thanks
