Ok guys I have a question about output. When I plug into channel 1 the volume knob is set on maybe #2 and it will deafen you. When I plug into channel 2 I have to turn the volume knob to 3 1/2 or 4 to get the same volume. Is this normal??? or should they both be close to the same. Now channel 1 has that select tone switch which channel 2 does not.

If you plug into the number two input on channel 2 is it then louder and more like channel one, or lower still?
If not then one of two possibility is that late in the 1971 production run of the K150s and 250s Kustom made a change to add more gain to the preamps and this in turn would make them louder for any givin volume knob setting, in short may be your amps channel two never got that late 71 mod, or that channel has a failing bypass cap in the circuit.

If that's the case then the amp has been worked on and the jacks simply reinstalled in the wrong position.
The number 2 input on these metal face amps just like on Fender and many others is 1/2 the gain of the number one input of a given channel.
And by the way in seing the course tuck and roll on your amp in that picture means that your amp has the factory gain mod in place that I posted about before.

Thank You Steve and Pleat for the info. I can rest at ease.
Ya know I would have thought that Channel 2 would have been the one with the most output because it is the channel that has ALL of the effects. But then again I am no amp engineer.
BTW serial numbers for my 2 K-250-4 are 82610 and 90346. If that helps
Thanks guys
Steve
