So, theoretically, say I have an amp head, that sounds great but woefully underpowered (50w!)... rather than lumber around a rack-mounted poweramp...is there any reason why you couldn't use a car audio amplifier rigged in the back of the head to serve as a slave? (the amp has a line out). There's no small form-factor poweramps around that are designed outside of the rack-enclosure parameters, and can be rather expensive. Car amps are often quite small and, once you've sorted a power adaptor to deliver the 12v DC it would expect, and made a couple of adaptor cables to connect...essentially you can have it all in one portable package. Thoughts? *EDIT as this was pointlessly ambiguous: I have a Traynor TS-50B that I need to be louder. I dont want to haul a whole seperate rack poweramp as Ive done that before and didnt like it. Does anyone know of a solution that I can mount inside the existing head (on the empty part at the bottom of the shell) that I can 'line in' for more power? Preferably +500w-ish. Nothing too expensive. Really, I just need a small poweramp. Thoughts?
