The power switch actually switches the 1.5V and 90V Battery negative connections. The yellow wire is from B107 90V pack and when switch closed (lid open) it's connected to chassis / 0V via 560 Ohms to provide bias for the DL96 grid which is connected to the yellow wire via 2.2 M Ohms.
It wasn't connecting HT- or LT- due to corrosion and wear. The contact at 0V end of 560 Ohms was corroded and also cracked. It was replaced with a small cut-up piece of battery clip from a €2 scrap Auto Scan FM Radio.
The yellow wire only connects to the resistor, no contact. The green wire contacts underneath.
- Yellow = B107 HT- via a tag strip
- Green = Direct to earth tag on Chassis near first IFT
- Black = Direct to AD14 LT- connector
