QED CD240 Amplifier Bridge Rectifier Issues

The relay may not be faulty. See post #6 re the delay components R31 and C31 and the instructions from @BSST on how to test them.

R31 and C31 lie below the relay in your first photo.

Give us a close up of C31 as it's out of focus - is that a brown deposit I see on its top?
 
pics attached There is NO brown deposit on top of C31 everything looks pretty clean, R 30 measures 271 ohm using the 600 ohm scale of a multimeter across R31 the meter stays on overload

When you power on, you should find about 33V at D1,C30. Look for rise in voltage at C31 and it should reach about +30V. If it doesn’t, you’re over the target. Easiest test is to tack in another resistor in parallel with R31 to see if that brings life. Otherwise, transistor or cap, etc.
 
You also mentioned transistor Which one?

I'll answer that part: it's T3.

It's on your schematic and physically right next to the relay.

P.S. The voltages you are looking for are also shown on your schematic (post #25).

The way I read it, if the voltage across C31 does not reach +30 V then the capacitor needs to be replaced.

The transistor doesn't have a Ref Des, but it's the only transistor in the "Relay Circuit" page within the service manual. If a paralleled resistor doesn't fix the issue, I'd suggest removing the transistor. Then you'll be able to monitor the RC rise behavior without the transistor loading.

Edit: Just saw @Galu has ID'd T3. Thanks!
