The Beta Bass amps are rated at 100 Watts RMS. Just about any 4 ohm bass cabinet will work. The footswitch is hard to come by, your best bet is to look on ebay. Go over to the Sunn Discussion Page and search for 'Beta footswitch'. There is a post over there on how to build one and replace the connector if you don't want to go to the trouble to get a compatible connector.
