  • Notes

  • The CN427, CN427A is an identical chassis to the CN421 "Gala". The difference from CN421 is the style of the bottom part of the case. See CN427 comparison photo.

    The only known difference is that CN427 from s/n 10998 use 330 Ohms instead of 220 Ohms for output DL94 grid bias resistor on  - HT to reduce HT consumption, perhaps these may be marked CN427A on the Rear lid instructions
