Vintage Simmons Drums (UK) Users Group

Hi would anyone know where I could get hold of Simmons Claptrap Schematics?

I bought a CT in 1981 or so and it worked until about 1993 when it started making weird (non-useful) noises. I put it in my attic and forgot about it. Cleared out the attic last year and rediscovered it and thought I should try and get it working again.
