Crypton Tuners

Did these tuners have torroidial transformers in their analogue electronics please?

It depends on the specific tuner model you’re referring to — but generally, most analogue radio tuners (especially consumer-grade AM/FM tuners from the 1970s–1990s) did not use toroidal transformers.

Instead, they typically featured:

Small EI-core transformers for power supply sections, or

Ferrite-core coils/IF transformers for signal processing and filtering (not toroidal power transformers).

Toroidal transformers were more common in high-end hi-fi amplifiers or receivers, not in standard tuner circuits, because tuners drew relatively low current and didn’t need the improved efficiency or low hum of toroidal designs.

I’ve no idea what haemorrhoidal transformers are but this is what I’ve always thought Cypton Tuners were

Yes, they connect to the flange rotors.
