I'm sorry to see you are having problems.

Is the original power supply a 'single' voltage one ? (e.g. 9.75 Volts)
Some equipment wants 2 (different) voltages (e.g. 12 and 9V on seperated connector pins)

One thing worries me :You write "It needs .....Volts AC (Alternating current)"

I could be wrong but the one you purchased is a DC (Direct Current) one ?

If it is a DC-supply, it is possible some parts of the VA do work (display etc). Other parts, as operational amplifiers most of the time need both + AND - voltages..... and the - voltages often need AC to be generated.

Please check the PS you purchased!
