Hello, I have an early 70's Concert Kasino, model: CON-L guitar amp ( my very first amp over 40 years ago! ) in amazing perfect working order except for the spring reverb, It's in the shop and I am helping the tech to try and locate a schematic for the amp or reverb unit so I can get back to jammin with this thing again! Any help would be greatly appreciated, thank you for your time and have a great day.

Hello and welcome to our obsession!
Your amp schematic can be found in this sites technicle section on our main page.
Your amps listing has three schematics and the reverb circuit board is a PC803 which along with the other boards in your amp is used in a ton of other Kustom amps from mid 1968 to mid or late 1970.
The reverb pans for these amps are getting hard to come by these days, and note that some new ones that will work do not sound the same!
The original part number for the reverb pan you nee's is a 4FB3A1B.
Here are the specs that your tech will need to know to get you a matching new pan.
Input impedance is 1475, and resistance check will read about 185 ohms.
Output impedance 2250 with a resistance check of about 200 ohms.
Both of these rca jacks on the pan are grounded.
The tank is a long decay type, but a medium will work good also.
The tank is made for horizontal mounting.
You or the tech can find these specs for the Accutronics reverb tanks at the AES supply site.
If you want to retain the amps orignal tank and its transucer coils are not open and resistance test good I can repair the tank for you even if the springs are busted in the center, or as is the case most times broken off at the transducer end"
