This is my all time favourite. The RAP models of 1946 have modular Chassis. They made 2 radio frequency modules, 1 intermediate frequency module and 2 power modules. The appropriate modules were bolted together to make the different models.

The 646 is a 6 valve, 3 short wave, medium wave and long wave set. The chassis is chrome plated and when polished looks impressive through the plate glass back. The large tuning knob has an epicyclic fine-tuning mechanism built into it, which works very well especially on the short wave bands.

This radio as found had a 6V6 as output valve and a 5Z4 as rectifier. Valve bases had been changed, so I changed them back and found appropriate valves from the valve data sheets.
