You can use this chart to estimate when your Kustom amp was made. Note this chart is only for amp heads or combos (K- serial numbers) - it is not for speakers.
(For speakers just add about 45000 to your SN and then use this chart.)

If anyone wants the exact production date of your Kustom amp, please let me know the following info:
Required
1) Serial number
2) Model number
3) Production code on top front frame of amp chassis - it is hard to read so please give me the different versions of what you think it says if you are not sure.
4) Color
Optional (these can be used to verify that the production date is reasonable.)
5) Transformer date code
6) Pot codes - all of them, as the most recent date is the most important.
7) Date codes of any other parts that are more recent than the transformer or pot codes.
I can identify about 80% of the production dates.

Hi, Les. I just bought the Kustom Amp below at a Guitar Center in Kansas City. It was a one owner and is in great condition and sound. Just want to confirm this was manufactured in the Fall of 1969. Also, any chance a spec sheet or manual could be found online for this model?
I am thrilled to have found this amp in such great condition. I had a Kustom 200 Bass amp in 1970 that I wished I had never sold. I feel like I got a piece of my youth back today. Sorry to ramble.
Thanks for your time.
Chuck
1) serial number - 46233
2) Model number - K1000-8 - (Kustom 100)
4) Color - Black

The serial #'s place the pieces in the July-Dec of 71 time frame.
The 4x12 cab was an option listed in the catalog.
If you go into the literature section and pull up the info on the 150/250/500 in the next to last frame on the left you will see your unit.

Hello!
You have replied to this string which answers most of the questions you ask about but for your questions in regards to the K250 head.
The the introduction of the metal face heads in 71 they reverted back to having two inputs on each channel of differing gain levels as opposed to tone on the earlier amps.
Also in 1972 with these amps Kustom added more gain to PC 5066 which is the channel without the selectone feature.
This simple mod involves changing out 3 resistors and 1 signal cap.
All K150 and 250 amps made after 11-5-71 will already have this mod.
If your amp was made after this date then you might want to remove the 4 10/32 screws from the bottom, slide the amp out the back and then remove the lid from the top of the amp which it should still have unless someone was in there already.
Once in there you will find the boards get interconnected by plug in cables.
You should unplug these and get some electromotive spray cleaner from a auto parts store and give both ends a good shot and then plug and unplug them a few times and you might find that' your low volume issue will go away.
If your 250 has no serial number plate on it's rear then you can date it by the numbers stamped on its power transformer, or on the control pots on its circuit boards, or even on its two big power supply filter cans on the floor of the chassis as all of these have date codes on them.
If you need more help, then reply back.
Also note that until you make 5 post I will have to approve them first before they go up to the board.
If you want make 4 more post in a row that just say test and I will delete them all at once and then you will be set!

Is a 1968 cabinet.
So now the question is if it's a guitar cab or a bass cab.
What does the speaker jack plate say on it?
CTS?
Jensen?
JBL?
Altec ?
If the speakers are original CTS would have been the base line Bass guitar drivers .
Altec or JBL where the step up drivers and there where different models for the Bass or guitar drivers.
Jensen where the base line guitar driver.
These days you can't assume that what the jack plate states on it is what you will find in the cabinet, so you either need to open it up or use a extendable mechanics mirror in open port and a flashlight in the other to see what drivers are in it without opening it up.
Also note that to make post on this site I have to approve 5 of them before you make a post that will just go right up to the board here.
Also note that this site does not accept photos, but the Facebook Kustom amp site does.
