Just picked up my third FP. Stab in the dark, anyone have a CPR playfield?

Quoted from gigawatt:Hi all, I picked up a #firepower that had been sitting in a barn for over a decade so it was subject to some pretty wild Michigan temperature extremes. I've spent the last two months doing some extensive repairs (perhaps I'll detail them sometime--it's quite a list), but I just completed the installation of a Hardtop so the playfield is now close to 10/10 in appearance. I've noticed when comparing to other pictures that I am missing a ball gate near the top right side of the playfield (near the "E" in "FIRE"). Does anyone know where I can pick something like this up?[quoted image]

Just snagged one myself.

I have some crazing too but I'm close to my 10th CPR PF swap and I don't give a sh!t.
The alternative is a shitty PF or Hardtop with 35+ year old inserts
You'll never see it when playing. I had worse on my High Speed PF.....I never see it, ever.
Be happy CPR is around.
BriPin, not taking a jab at you....I'm typing this with a smile and happy I have another project

Quoted from crujones4life:Got my boards back after having them repaired. They were tested working before sent back to me.
When I power on the machine all 4 pops and the slings fire then all but one coil (left upper pop) releases. So for now that connector has been pulled. I have tried testing Q2 and I think it's ok. It seems to get similar readings as neighboring transistors.
Also, I have no sound. Sound test does nothing. There is no speaker hum.
I also replaced a connector going to the power supply. I did this before connecting boards and powering on for the 1st time.

Also the voltage on the 3 gray wires from top to bottom are 10v, 10v, 0v.

The voltage on these 3 gray wires from left to right are 10v, 0v, 10v.
I get 0v on all 3 test points on sound board.
Should be:
TP1 12v
TP2 -12v
TP3 ground
TP4 5v
So...any ideas?
Are you measuring AC or DC for the power to the sound board?
What wires are plugged into 10J2, they do not look correct in your picture?
Quoted from crujones4life:AC voltage.
Work backwards from those grey wires, they should be 18VAC. IIRC they come directly off the transformer

Quoted from Xtraball:Awesome! I would think 7 digit score displays are necessary too then?
That too is already done

Finally got my FP back together after 2 years, everything is working except I have undesired activity when activating either flipper.
Right flipper is lane changing properly but also spotting the F-I-R-E, scoring 1000 points and Callouts are FIRE or FIREPOWER
Left flipper is scoring 1000 points. It has no effect on F-I-R-E.
Any ideas?
Ran the above mention test on the whole matrix, no duplicates.
Going to go back to the wiring one switch at a time looking for anything obvious. Other than de-soldering all switch diodes on one side to test with a DMM, any other suggestions?
