Hi.

Just picked up January 2022 issue of Practical Electronics magazine from Smiths and noticed an interesting project that might interest you. It's a battery valve power supply using Li-ion batteries. The circuit will provide the valve heater supply as well as the HT.
Quite a useful circuit where no mains supply is required, ie it is truely portable.

Regards,
Symon
