with the 6080 tube removed, the voltages are -

PIN 1 =  94 VDC
PIN 2 = 229 VDC
PIN 3 =  0
PIN 4 = 228 VDC
PIN 5 = 222 VDC

Hi Paul,

I de-soldered the wire at A1 and cut and soldered in a new one. Fired up the amp and the both LEDs now light up and I have both channels playing again.

Many thanks for your help  :)
