Default A most unusual little radio

The name on the dial is Tefi this was a purchase from Ebay I felt sorry for it it was a right state the case was in bits ,but I do like a challenge ,the front of the cabinet is the only original bit left ,I made the rest from thin oak. it measures 6"x 4.25x 4.25 "
The chassis is a TRF using Valvo valves I had never come across before ,it was a bit confusing to start with as the bases of the valves are the things you see from the rear view ,to remove them you push the top cap the valve comes out from the rear.
A small 33v tx was squeezed in to supply the heaters three volts low but works ok I left the old rectifier in as it worked ok supplying about 200v ht via a dropper resistor , a new wave/change switch was fitted on the rear , plus a new speaker, re stuffed some of the capacitors new smoothing added , It works very well with a good signal.
