Also had this to say about power filtering;
System 9 MPU Williams used a single version of the System 9 MPU in all System 9 games. A few minor modifications to the board may have been made, but it's essentially the same board for the entire 3 game run of Space Shuttle, Sorcerer, and Comet. The picture at left shows an early board that featured two inductors (copper wound coils that "smooth" DC power) at L1 and L2, adjacent to connector 1J17. Later revisions of the board used "zero ohm" jumpers instead, presumably to reduce cost.
Anything there i should get him to check out?

Thanks, i did find them on the wiki, is this pic the ones?

No, Daniel is referring to the main filter capacitor in the high voltage section of the power supply.
As he suggests, if it has never been changed it could be dried out and causing the flickering you're seeing.

Says to change diodes to drop the voltage from 100 to 91 volts, is that something you guys would recommend as well?
Gotta duck out but will keep trying to find an answer this afternoon, i really want the machine to be perfect for Pinfest.

Thanks Mitch, trying to find a part number to order one and found this page.

Yes - the 91V Zener will prolong the life of the display, but won't fix the flickering. Run with the suggestions of replacing the Capacitor first.

The other two parts i need to source are the chrome lift channel and speaker trim that look like they weren't replaced in the restore, hoping it's just a budget thing rather than a difficulty sourcing new parts?
Looking at RTBB but not sure how to identify the right parts.

Found the backglass channel, but need the speaker trim still.
Is this the part?

The 1/8 stainless lift channel has Sorcerer in the list of games that it is used for. We have 17 in stock. Let us know if there is anything else you need !

It's only light surface rust from fingerprimnts rather than deep pitting.
Neil was here yesterday and said there were two capacitors (250v 100uf) one on the 100- and one on the 100+.
He thought that the Zeners were D4 and D5 but i haven't found out yet the values of them to reorder, need to reread the page with the tech stuff on it.

They are all rated the same but have different connections and sizes as far as i can tell. i've tried the wiki and google to try and find a part number, and searched all the part numbers i can find written on the ones that are there. i have NFI how to find the zener diodes at all either.

Meantime i have been researching the speaker system and have ordered new speakers;
a pair of 10 x 4 for the front speaker
https://www.ebay.com.au/itm/183045742771 (https://www.ebay.com.au/itm/183045742771)
And a pair of 6.5" for the cab speaker
https://www.ebay.com.au/itm/173130666612 (https://www.ebay.com.au/itm/173130666612)
I'll have a spare pair to do another machine.
Also got the speaker cloth coming from Element 14. Just waiting to catch my boilermaker mate to see if he can polish the mild steel and clear it or something that's on the trim. Can't seem to find it for sale anywhere. Lift channel is available but the two trim pieces are hard to find. Really don't want to paint them black so i'm hoping it's possible to polish them, but i don't know.

I'd like to convert the white plastic acorn nuts to black too, but no-one seems to have enough stock here in aus. lots on ebay, but i don't know what size they are.
This stuff is easy for you guys, but every little thing takes me hours to find.
If someone could tell me the specs of the nuts i'd love that.
These ones are m4 and i'm guessing they are what i want but i don't know and i bet you are itching to hit the buzzer. $#$

Going to pull the coin mech today as one of the coin return doors is wedged open and it's pissing me off. First time with one of these but it looks reasonably straight forward.
I want to replace all the gal screws with black on the plastics and backboard where the eys are, then replace all the white acorn nuts with black on the orange and black plastics and leave the white ones on the 3 white plastics.
I know it's not stock, but a little detail that i think will improve it for me anyway.

Trim all polished up, speaker panel cleaned and now the coin return fixed. Running out of things to nit pick on this, although i'm sure the pro's can find plenty.
It's also playing very well, my improvement on the factory high score of 251 mil lasted only a couple weeks and i got my arse handed to me last week and it now sits at over 350 mil. <.> *)*

Guys/ladies, i asked my tech mate Neil to point to me the simplest way to replace the drop targets on Sorcerer in anticipation of the new ones arriving on the weekend but we saw a squirrel (nowhere near as distracting as the one above) and he forgot.
Targets turned up today, but do i need to pull the entire mech out, or is there a simple way to get at them?
Can lift the bonnet and take a pic if needed.

It sort of looks to me that if i undpo the 4 screws holding the bottom bracket that stops them falling out i may get enough angle to slide the targets out past the switches?
