One other bit of information on the voltage selection switch.
I kept the original multi-voltage selection switch on my Beogram 4000.  It just doesn't switch anything now.

How does this stack up for the voltage regulator?.....

And I'm thinking these parts need to be replaced with the regulator?.....little guidance required here

Hmm...that's just a standard run-of the-mill voltage regulator. The dropout voltage is 2V at 1A...it might work...if you're lucky...

Personally I'd reach for a real LDO, e.g.

Thanks for that Manfy....

Hopefully I will get some time to take some measurements to firm up the current and voltage levels under operating conditions...I'm happy to mount the voltage regulator off the circuit board so using a DPAK version will be fine if necessary, Dillen advocates moving 2TR6 off the board due to heat build up causing fluctuations in the 6v rail....... 

Ok....first set of readings measuring between the 6v transformer output and the bridge rectifier 2D5.....MIN reading

MAX reading........

Average Reading.........

Lost the AVG reading.....no doubt it will turn up.

This reading is the Voltage measured at the output of the 6v transformer winding with no load....

Same measuring point with load.....
