Thanks Andrew. It has the Vol Control on the back of the Amp. I was wondering if I should open it up and see if:
- there are any caps bulging or
- if there are any dry solders I could see or
- if there are any obvious problem with the 3.5mm sockets
- or???

It does not happen all the time (eg right now it is fine but it is morning here in Aus and I've just started listening) but when it does, it then happens for the entire listening session, hence the idea it may be a dry solder / heat soak but I'm just guessing.

Thanks
Nathan
