The K50, will give you the full 25 watts rms output with a 8 ohm speaker. I agree with KustomBart, that the KEI 16 ohm speaker in your amp may be a factory replacement since Kustoms had the lifetime gaurantee on speakers. I use the K50 as my main amp, and I've tried JBL, EV, Celestion, Eminence, and always go back the the Jensen C12N. Regardless of brands, just be sure to use an 8 ohm speaker.
The back vent plates are the same as found on your Kasino PA columns.
Nice looking K200A guitar, but I'd say the pickups are not original to the guitar, in repect that the K200A models used the adjustable pole piece. The pickups in your guitar are the model that the K200B and K200C models used. The other odd thing I noticed is the bridge has the slanted ends which would be found on the earliest models. Later models the bridge ends were straight.
I was working at a music store in the60's and 70's and remember when Kustom was closing out the guitar line. We bought 7 of the K200A guitars in wineburst and some had odditys. I just figured that kustom was using up all existing parts to complete a guitar.

The serial number of the guitar places it at the end of the guitar building era. Bud said that they produced 3000 instruments with about 10% being the K200D bass model. Your guitar headstock is the longer horns, where the original 67/68 models have a shorter horn headstock. If you look at the big 69/70 catalog on this site, you will see all three model Kustom guitars. The K200C model has the short horn headstock with a 4 dot neck, the K200B has the longer horn headstock and is a two dot neck, the bodys and electronics are identical. The K200A also has the longer horns and 4 dot neck. Kustom added the K200C to use up earlier made K200A necks. Both the C and B models use the cheaper single coil pickups. Also the original guitars came with a rectanglular case, not the shaped case. If you remove the pickguard you might see some shiny solder joints indicating that the pickups may have been changed out.

The Jensen C12N should be black with a round magnet and a red and gold sticker. It will say in white lettering around the edge (where it would mount if mounting from the rear and not the front) It will give you the code telling you it is a Jensen and say C12N. I bet Pleat has a pic of one, if not I will dig and see if I have one.

It's hard to say from the photo's but All the K200A and B model guitars the pickup wires are black. The K200C body came with a hanger tailpiece, not a Bigsby. The long horn headstock and shaped case and the serial number still place it towards the end of the guitar production. The pot codes of 68 isn't surprising. Kustom would buy in bulk, and could be a couple of years before they would need to reorder pots for the guitars and basses. I guess I'd be happy that you have a nice example of the Kustom guitar, even if the pickup is the mystery part of the equation. I personally tend to think that the PU's have been changed out.
I run one of the newer Jensen itialian made C12N in one of my K50's and sounds as good as my other K50 with the original Jensen.

Johnny, they appear to be the same - the plastic was probably a cost-cutting feature used on the Kasino amps
