I have both amp heads and the 250 has a much more solid punch than the 200. Think that Stevem posted on here that the 250 has a bass boost circuit and the 200 doesn't. 250 is the way to go for bass unfortunately they are a little harder to come by and more money usually.

Hello and welcome if it's your first time!
The 250 heads are a far better head in regards to tone control and to some degree clean head room and punch over the K200 B series head.
As with any Kustom head the more effects it's made with the less ultimate output wattage it will have, a fully stacked up 250 will do 112 watts of clean power into a 4 ohm load but a 200 will only do some 92 watts, a K250-1 head will do 119 watts into a that same load impedance.
The metal face amps like your 250 also produce less hiss for the amount of gain they have and that's due to them using newer FET type transistors and intergrated circuit chips.
If you have have the -1 head you can jump both channels with a short cable and make use of the tone sections of both!
Note that these amps where made before active pickups where around so the hotter output from such a axe can clip the preamp even when using the second input Jack which is a 3 DB down input Jack.
This brings up another point if you get a K200B head as in those ( other than the PA 200B-5 head) the two inputs on those heads per channel are for brite or darker tone, not different signal levels like on the metal face amps!
I hope this helps you!
