It was staring out of an add on Ebay like a puppy in a rescue shelter...….

A number of switches are jammed into the selected position and its full of debris, but they all are after this length of time....and what is one to do, cant just ignore it....

Why am I calling it a BM5000.....Beolab would be more appropriate 

These will have to go to Frede…….expensive but its the only way.

With the panels removed the selector switches freed up nicely, switched everything off and after a visual inspection revealed nothing obvious decided to connect up the variac and see what a little power does...….

And the answer is nothing....no signs of life and no current pull as the variac was would up, fuses checked out fine...….connections into the voltage selector switch also look fine, will check this out in due course.

Couple of measurements inside revealed no power was arriving at the voltage selector, inspection of the power cord showed the reason for this, a slight nick in the outer sheath.....when pulled apart discovered a break in the live side, the insulation is very flakey, peeled back far too easily. Will be replaced with a new length.

This time I powered up I was rewarded with a current pull of around 140mA, quite happy with that...

No power on lamp however.....inspection revealed a broken filament, replaced it with a spare 60v 5w and when powered back up got a nice glow.
