Hybrid Valve / Transistor Portable Multiband Radio
In the crossover between valves and transistors some manufacturers found ways to combine both - for example Bell had the 34P7. Philips produced this little gem, the Transworld Portable, which uses valves in the RF stages and uses solid state parts in the audio stages.
2 versions released - according to the schematics the MK1 was produced in 1957, and the MK2 the following year in 1958.
