I recently bought a working one for $650 - Rough cosmetically, but it played all the way. I'd give no more than $200 for one as you described (probably offer less). I have owned 5 of them over the years. The one I bought for $650 is getting a repaint and new playfield, backglass and plastics. I expect it to look incredible but I'll easily have more money in it than it's worth. Not a problem as long as I don't want to sell it.

The machine you described in working condition is worth about $650. Since the rectifier board is not working, there are 2 options when determining value. If you have the means to show up with a working rectifier board (and transformer assembly), it would definitely help you. Without a working rectifier board, it is kind of like buying a used car with a dead battery. Since you can't start the car, you don't know if the engine or transmission work. If you have a working rectifier board, you should be able to see if the MPU is going to boot. If all you needed is a new rectifier board, I would deduct $100 from the estimated value. However, if you don't have a working rectifier board to test in the machine, you run the risk of the MPU, SDB, and displays not working. In this case, the machine is worth about $200.

Non-working in excellent cosmetic condition no more than $200. Serious backglass, playfield, or cabinet wear and non-working $50.

I sold recently a routed, but Minty one with Bright Crisp Boards for $850.

Greatest backglass ever!

I bought one in similar condition with a bad rectifier board and locked on knocker transistor for $250. I bought the repro rectifier board and replaced the transistor and shopped it out and it's great. Love those chimes and everyone wants to give it a shot when they see it.
