Valves/Tubes used in this model:
41STH (frequency changer)
MVS/PENB (IF amplifier)
DDT (det./AGC diodes, AF triode)
2P (output triode)
43IU (rectifier)

The 2P output valve is a type developed to circumvent the wartime restrictions on output valve power and has an anode dissipation of exactly ten Watts, the maximum allowed without obtaining a special permit.

The loudspeaker is a 20cm dia. electrodynamic type.
