Pyramid 1800

Dear Pyramid
Hans Polak suggested I look into it
I read your suggestions about the AC motor controller on the forum.
I am looking for a solution that will help solve my problem.
I started copying an old record player. It was manufactured by Mechlabor in Hungary under the name SL 102.
I want to make it with the original engine with direct drive.
The controller that was designed back then does not work.
Send me a picture and if you can sell it for this purpose or can be made with help (I'm a mechanic, not an electrical engineer).
I would be interested in any solution.
Engine Papst original.
There should be a Digital RPM display from the plate with a Hall sensor.
H-bridge + transformer
Please help me to solve my problem.
Greetings András Strácz Hungary
