I just purchased a Kustom 250 tuck and roll. The reverb and tremolo did not work so I took it apart and cleaned the in and out female jacks and connections and now the reverb works great but still no tremolo. Any thoughts or input? I have a foot pedal that came with it but is not a original kustom with three wired jacks and dosent seem to do anything. Thank you in advance.

Welcome to the place.
The effects should work without any footswitch connected. If you look at the back panel of the chassis, there should be a metal tag with the model number stamped on. Something like K250-2. If you tell us exactly which amp you have we can point you to the schematics in the technical section of the site.
If the connectors for the pc board have been cleaned and the solder joints have been checked, there may be an electronic problem with the circuit. If you have the skills, we can help you fix it or help the person that fixes for you.
Again welcome.

Pleat out of my 4 k250 amps 3 are the -2 model.
Two of them are first production -2 models and one is a late 1972 model with the course black T &C, and all 3 of these use a 4 pin XLR .
My late 1972 K150 head also covered in course black T & C is also equipped with a 4 pin XLR so that's all I can confirm!
The one main thing I would like to know is what bulbs Kustom used in the foot switch because I do not think they where using LEDs yet judging by the 10 watt voltage dropping resistor that was used inside these amps to feed the lamps!
