New here and wanted to wave hello to all and thank for any future help i get.....  im damn sure im going to need it..lol

I'm new to the forum and just got my hands on a ampeg VH 140c and know nothing about it,  not even sure where to plug in my internal speakers to what jacks. All I know is that this sucker sounds bad ass! If anyone know how to set up this amp so I can use it like it was made to be used would be great. Thank you.
