Still being new to the whole elctric thing I'm trying to work out what the 'equivalence' is between the wattage of tube amps vs ss amps. Tube amps seem to go up to 5 watts for prac amps & jamming, and then from about 15watts upward for small gigs. I've seen it mentioned on some sites that ss wattage is equivalent to tube wattage multiplied by 4, 5 or even 10 depending on which source you happen to quote.

So what would a 5watt tube amp compare to in a ss amp in terms of volume? Something like 30-40watts?
