I looked thru 360 of Les postings and could not find the location of the serial number chart. Please help with finding location. I have serial number 25074 and am curious about history.

Would also like to get manual for k100-1 and 1-15 CTS. Please post location for manuals.

Thanks,
M.

Hello and welcome to the board!
The production number of your K100 puts it in the Jan to June 1968 range and if you care to narrow this down even more than you can look inside the amp or on the magnet of the speaker.
Inside the amp the pots are dated with a 137 prefix which means CTS manufacture followed by 4 other numbers like 6872, which would mean the 72nd week of 1968.
The face of the power transformer is also stamped with a string of 6 numbers the last 3 being year and month, like 824 ie 24th week of 68.
Also the 2 big 2500 mfd power supply filter cans in the amp are labled with a date code that I think starts with 235 if I recall right, and if the amp has reverb than the pan is ink stamped with a date also. The magnet of the CTS 15" driver is stamped in white ink with a 137 just like the pots and then the 4 diget code like the pots.
Manuals are not to be had from this site, you will likly only find them from private sourses on ebay.
Hope this info helps you out.

The 72nd week of 1968? Last time I looked, years only have 52 weeks. I know there were alot of drugs done in 1968, but 72 weeks?? That's a lot of drugs!! Laughing

I just did a search of the board, and see that Les has removed all traces of his serial number list, and is no longer a member here.

I'm sorry to see him go. His list was a great reference tool.

Hey Bill, back in 630 AD if I recall my history right, the rommans had to add 3 months( that leap year thing) to that year to get their calender back in line with the seasons, and they called it the year of confusion!
May be thats what I had on my mind.LOL

I guess I must have been out of the loop. I didn't know that he had pulled away from this site and took his toys with him. Hope everything is ok with him.
I personally never put much stock in date codes, it just tells us when the part was made. Buy a train load of pots and see how many months it takes before you order another train load of pots.
I agree it gets at least some reference when date coding all the componets from an amp. Seperate amp and speaker cabinets after 40 plus years, the dating gets a little cloudy. I know as a dealer in the 60's when a speaker failed, we sent it to kustom and they sent us a re-manufactured speaker as a replacement. I don't think they removed the original manufactures date code, they just put a sticker on it saying it was re-manufatured. In fact I just bought a K150 SC with the 2x12 speakers, looked in the back and saw one original Jensen and one with the remanufactued sticker on it, with the gold label removed. I bought it from the original owner who's wife worked at kustom when I was in Chanute at the convention. They bought it 8-26-68. For me it all about owning and playing the amp.

Don,
I don't use date codes to date Kustoms.
I use the production code - the one that is on top front frame of the amp chassis. This production code is on every Kustom amp made after about SN 19000.

Kustom went from the K25/K100 combos to the K50/K150 combos in July 1970.

Good to know, I know kustom would swap serial numbers, make up numbers and use serial numbers from customer repairs to make up more inventory at certain times for business reasons. I get a lot of players sending date codes from their guitars to pinpoint the guitar's manufacture date. There is a guy in CA who bought a ton of old fender parts in the early 70's when he was leaving Fender, built some amps and is now back in the amp business using original 70's parts, so I guess at some point in time someone will open up the amp and swear it was built in the 70's according to the date codes.

There is another thread that asked for a date using the S/N. The chart that I have pinpointed the date to 1/15/69. That is pretty darn good. Les, are you still accepting S/N's to add to your list? Thanks for all that you have done.

This was from another entry here. I have k200 by ross. M# 200b 5 .... s# 32877. That is very close to another B-5 on 1-15-69. I still need to copy all of the S/N's from my stuff and send them to you. What happened that you didn't show up on the site's search? We oldtimers need to stick together. Did you make Chanute? I'm sorry I didn't. I noticed from the pictures that my red K100 was in attendance but no one sold it to me yet. It WILL show sooner or later but at an inflated price. Thanks again Les.
Conrad
