Premier Radio 3 valve TRF receiver.

[Geordie McBoyne]

Presenting a two valve TRF radio which was offered in kit form by Electronic Precision Components Ltd. It's the Midgetronic home build receiver. It uses two SP61 RF pentodes and for the HT rectifier an ex-radar valve, the VR135, a strange choice of valve but I reckon it's up to the job as the HT rectifier.
A germanium diode performs the function as the detector, if one wishes to keep the set all thermionic then the EA50 or VR92 could be considered.
The attachments show the circuit diagram and some constructional details.
