On the power supply side of things all the smoothing capacitors appear OK.
The ‘Super Seven’ has different reel motors to the earlier Sevens and has 1uF caps across one winding section which I assume are phase-shift caps. These are Siemens on this set but someone has shunted them both with an extra 0.1uF - see pic.
Across the motor switching contacts Ferrograph have used moulded 0.1uF (Dubilier?) caps in series with resistors.
Haven’t seen a Rifa in it.
