Hi there and welcome!
Yeah the electrics are built so they temp swing to keep the chips/wood smoking.
Once you switch to a PID controller you will have to provide smoke a different way an improved way to supply smoke in my opinion).
This PID should handle the Amperage and Wattage requirements of your smoker (12.5A 1500 Watt over 120V):
Auber Instruments, Inc. Multi Purpose Controller [WS-1510ELPM] - The WS-1510ELPM is a versatile temperature controller to have in your home. It can be used for various applications such as Sous Vide cooking, controlling an electric smoker, making yogurt, dough proofing, controlling the...

You just turn your dial to max and plug the smoker plug into the PID and the PID will read the temp inside the smoker and cut power on/off to the smoker to hit and hold the temp you punch into the PID.
With all that said you are going to lose the ability to burn chunks or chips in your smoke pan but that's really no big deal because you have a better option!
The option is called a "Mailbox Mod".
If I owned an analogue smoker like this I would get a 3inch hole saw bit and drill a hole in the side of the smoker opposite of the power cord and between the element and lowest meat rack.
You can then use 3inch duct joints and such and build a mailbox mod.
In the mailbox mod you use the A-Maze-N Pellet Smoker (
AMNPS) tray and burn wood pellets.
The
AMNPS tray provides PERFECT Thin Blue Smoke (TBS) with no fuss for up to 12 hours!!!!
So with this kind of setup you have the PID for great temp control and the mailbox mod +
AMNPS with pellets for perfect smoke for up to 12 hours! My setup is like this except I have the digital MES40 and my mailbox mod is super compact and uses a wall hanging mailbox instead of a traditional mailbox:

Finally, the analog units have zero insulation so later if you are having trouble hitting and maintaining heat you may want to get some kind of insulation wrapping (mylar type or welding blanket type) and wrap your smoker to insulate it. One guy went as far as to take out the inner wall of his analog and stuffed it full of fiberglass insulation (doesnt burn) and then reassembled it to have a rock solid insulated analog unit :)
I hope all this info helps :)
