Found a Clairtone 7980 in super shape but unit will not work (power up)

Any ideas , suggestions would be appreciated ...

Cheers

Try using batteries - It's all I operate mine on  Why ? cause they are PORTABLE

I brought it to the local electronics guy that worked on them years ago.

The machine would not power up on batteries or a power cord...

He tested it & said there is a problem in the power console area.

Will I have to find a replacement part to get this working ?

Does anyone have Clairtone 7980 parts ?

Thanks
