I believe what you are looking for is a 11150Kc, 11200Kc, 11250Kc et cetra each additional rock in that order will get you more channels. http://www.cbcintl.com/XTALS/AM 10850-8615-7500-7975.pdf
I leave the whole 22-25-24-23-26 mess to you .
So you're not out of luck, you're on your own with enough information to be dangerous. ;-)
I'll even give you a head start
http://www.af4k.com/crystals.htm
dig through Bry Carling's site and see what you find.
and if that doesn't work...
http://www.linear.com/product/LTC1799
or if you just ...
https://www.ebay.com/itm/1KHz-to-33MHz-Adjustable-Oscillator-Module-LTC1799-/400292172818
Keep in mind that you'll have to create a "dead spot" or disable the rear section of the selector
and
either wire in another rotary switch with the additional crystals and or inject signal from an oscillator of some sort.
Attached is the schematic for the original Range Gain

That’s what I like about this site someone always willing to help out. Good job Kopcicle!!!
Thanks for the info...This is way over my head so I will just leave it alone and maybe get another radio

That would be the best and most economical option I think.
LOL Kopsicle!
this guy joins the forum three years ago, finally has something to post, and you knock him right out of his chair!
you and i both know he was hoping for sort of an "add a resistor here" type of response and you've got him digging through crystals and adding external oscillators. LMAO!
seriously though, you really did go above and beyond the simple "no" answer, and actually gave him a couple of options. kudos for doing the legwork.
I always enjoy your posts and hope to get to read them for a long time.
Nobody!
im a smartass and don't mean any disrespect by commenting about your post count.
sandbagging is a sport in and of itself and is practiced by many a member here.
I hope we can help in your search for your next radio.

It’s merely a single crystal swap if you’re mainly interested in just one particular channel that is locally used in your area. The simplest solution is to swap out the 10.850 crystal that gives you Channels 1 to 4 and replace it with a crystal that will that will cover your desired channel. Of course you will need a cheat sheet to remind yourself what 1 to 4 have now become. If you decide to sell the radio later swapping the crystal back to original is easy. No holes or switches to distract from the price. Many buyers want those old classics left untouched. If you name that channel, I can give you the frequency of the necessary crystal. Hopefully one can be found at a reasonable cost without having the crystal custom made. Custom made crystals are expensive. They’re typically in the $35 range. I agree that having all 40 is not very cost effective, at least for that model.
I have only had this radio since 1962...I was prepared for the answers I got but I just had to ask. I will continue with the 23 for old times sake and look for newer technology that satisfies my deal....BTW Not thin skinned
Can you say external VFO???? How much slide does the clarifier have some 23ch tube radio's had so much slide in the clarifier you could actually get close to the full 40.
