so im making a start on this, and its in realy good condition as it happens
I have no DV voltage at the terminals, which is a good start, just a couple of mv's on each
I do however have 1.8v AC on each channel, im not familiar with this amp yet so i dont know if thats normal or not
Just testing out a few of the old caps and the first one (500uf-64v) is as attached
not sure if this ripple is what it should/would have been) but it isnt bad considering its age

Not familiar with the amp so feel free to disregard but,
Yep, agree. Since both channels affected suggest look at the common area (power supply). Determine if hum/AC wave is mains 50/60Hz or rectified 100/120Hz, then troubleshoot before/after rectifier accordingly.
