Hi, I have what I believe is a 1972 250-4 (SER# - 105166). The schematic under the top cover is dated 5-72.
Question is that instead of the 6 pin XLR connecter for the effects pedal there are two stereo
1/4in. jacks. The fuzz and boost are on one jack with the reverb and tremolo on the other.
Each of the jacks have a round ring designating what is for so I'm
pretty sure that this is how it was made and not a modification.
Also there is not a punch out for a XLR connecter on the back of the amp chassis.
I know that the Little Joe Kasino amp was set up like this,
but has anyone ever seen a another 250-4 with this configuration before?
Looking at the schematic for this amp it's how it is suppose to be.

The Serial number places it between July and December 1973 using a chart that LesS posted on this site some time ago.
The amp is not that odd. The first series K250-4 amps had the long lighted footswitch with the XLR plug. At some point, Kustom was cutting production costs and changed to two stereo jacks for the foot pedals. Your amp case may be Particle board rather than plywood. Another change to cut costs.
