Ed,waarschijnlijk bedoelt Jaap deze weerstanden.Ik ben ze al eens tegengekomen bij de restauratie van een Engelse Philco.

""High Stability resistors""

Special "High Stability" resistors with an extra pink band (sometimes called "salmon" ) to indicate their superior quality. From left to right, a modern 4.7kΩ for comparison, a 68kΩ, a 3.3kΩ, two 56kΩ, a 220kΩ and a 2.7kΩ. All are 5% tolerance (gold band) apart from the 56kΩ, which are 2% tolerance (red band). The modern resistor is a metal film type, but the older ones are carbon composition. They were wax coated for moisture-proofing.

Vriendelijke groeten, Armand
