I have recently picked up a Lead III
Model 111L PU
Serial K 214663
Ive never seen the PU in anyone's post. Does anyone know anything about it? Year of production, what PU means, where I can find replacement pots for it...

the 111L is the big K series and the PU is for power unit. 130 watts. Sometime around Late 78 would be my best guess. No idea where replacement pots can be found, but I'm sure one of the techs on this site may be able to help.

I can not find your serial number in my chart, but I also can not find a schematic to help you out with your pot question .
Since you have to unsolder the pots to replace them we can then find out there value and at that same time since the pots have production dates on them find out when your amp was born.
Note that the two big can type power rail filters will have dates on them also !

I found that your schematic can be perchased at Musicparts.
In terms of a 4 ohm cab to run the amp thru are you asking about just Kustom cabinets, or just in general?
Any cabinet with two 8 ohm speakers wire in parallel that is rated for 100 watts rms would be fine.

Are you looking for new cabinets?
If so companies like Mojotone offer a bunch of different cabinets and can load them with many different speakers to get you a 4 ohm load.
