Internal view of Wireless Set No. 62 Mk.2. (left) Examining the layout of major components such as the receiver (left hand side) and the aerial tuning arrangements (right hand side of chassis), there is a strong resemblance to Wireless Set No. 22. Wireless Set No. 62 was based on the No. 22 Set specifications but the circuit arrangements differed completely.

Note the use of aluminium for the chassis and front panel, the case was constructed from pressed steel.
