Giving us the model name would help a lot like mine is called 325.1.

Where do i find the model number??? I thought it was just Punch 150hd

That is the model. The Punch 150HD started one after the Punch 150. I don't recall what the HD stood for but the amps very similar. Maybe some hybrid design power supply, or something to that effect.

Hmm??? all i know is it is the first couple of years they started making amps...they are really old but hit very hard
