so I got my 69 Williams Suspense up and running and it's a lot of fun but it feels like it's playing on high tap. its very fast and the chimes are very loud but I switched it from the high to normal position when I got it. After a dozen games it was clear this wasn't normal so I decided to check the voltage after starting a game to put some load on the transformer. the 6V secondary reads 6.4 which seems well within specs but the 24V secondary is reading 30 and the high tap reads 31.5. it seems the 24V circuit is 25% above where it should be but the 6V circuit is ok?
also, the line voltage is around 123V.
any ideas on how to drop the voltage on either the line or 24V secondary? as it is, it's too easy to score and more importantly, playfield damage is likely.

that’s interesting so what’s the better route, a variac or bucking transformer?

ordered a 130V variac off amazon so that should have me covered as the Suspense schematic shows the incoming line voltage at 110V which is quite a disparity. damn, prolly shoulda ordered 2 variacs since I have pins downstairs.

Got the variac in and it works great. I placed it inside the cab in the rear and I like being able to dial in the exact voltage and the action now is much more appropriate. Well, it’s actually as the factory intended.
