The circuitry in this radio is a testament to Standard's commitment to building a radio that will deliver the best possible performance. The radio uses mica condensors (Sawafuji "Silicondo" condensors), and the volume switch is given its own mica condensor as well as a tubular electrolytic condensor, presumably to eliminate any noise. In addition, the pair of HJ-17 transistors are fitted with a heavy-duty heat shrink. This extremely fine workmanship is probably one reason why the radio continues to play so well today without any servicing.
