Thanks for everyone's reply
@Kevin,
The reason I fitted a new PSU is because that is what Palsite recommends. I tried replacing the non polarised caps already in the old PSU but a getting replacements for the fusible resistors and transistors are nigh on impossible unless you have a source? I concur with your findings though!
I don't know the history of this machine but the LED VU meters are all intact thankfully!
If you can kindly help me track down the components I would love to use the old PSU
Thanks!
