Changing mains voltage on Accuphase power amps

Wherever you read that said it was easy but offered no instructions or advise?
Model number? Look at the service manual. The transformer must be capable or have multiple primary taps to start with. Generally some models have a selector switch or shorting/ configuration plug and some are hard wired, need to investigate your specific model to know for sure

It depends on the model, most of their older model amplifier has printed voltage selection table on the power supply board and use quick disconnect terminal, make it very easy to change voltage.
However, their newer models are harder to change voltage without a service manual in order to protect their distributors.

@chrisng thank you very much indeed ! 🙂 That confirms as I suspected that its the same as the A-60 and A-65 for which I have found service manuals; as you mentioned previously its just a question of switching the wires from the transformer based on the guide they provide.
May I ask where you found the photo?
