Recel Lady Luck transformer help!

[Rpearsonx]

Hey everyone,
So I bought a Recel Lady Luck at the start of the year and have finally gotten round to this project.
Now my big issue is... there’s no transformer in the machine, there is a loose transformer that was sat in the cabinet that is not from Lady Luck but has no lug labels on it.
I figured my best bet is to have a new one made, I found a company that would be able to help but my problem now is I have no read outs of Volts or Current ratings needed to make a new one and I think few are missing of the IPDB schematic (linked below).
If anyone has a Recel Lady Luck and can please help me or can help in anyway it would be hugely appreciated!!
Thanks in advance for any help.

looks like 28v and 6v is all you need. probably 15a on each.

You could go off the shelf dc power supplies. 24v 20a and a 5v 20a one are cheap enough

 

[AlanJ]

on the 6v lamp circuit 30a. just looked at the fuses on the schematic. 3 x 9a

You would not need 30amp 6volt if you are using LEDs.

The GI would run better if on DC 5V PSU.

Thank you for the response, Ohhh awesome, do you think I really just need the 2? Thanks for the help, I’m not too bad at reading schematics but a bit confused when it comes to the main power, I was thrown off by the 30V&32V wires that go to the top area

Thank you for suggesting this, I have fished 90% of the working bulbs for my other pins I was working on so I think LED may be the route with this one!
Just need to figure out how to power everything first and get it up running thanks again

there ain’t much difference between 28,30,32v so you could just use a single voltage for them all.

Ahh okay that’s great! Thank you. So as you said earlier I could look at using a single DC power supply to power the main parts and another one to power the GI? That would definitely be a lot easier than have a whole transformer made!

 

[AlanJ]

yes.

Interesting thread, I had a Vector here with a laptop PSU as part of the power supply and another with a missing transformer, so sympathise.

The dashed box above is the voltage adjustment to the "bumpers, flippers and kickers" that are rectified DC (the rest runs on AC like most EMs). I guess this comes into play to fine adjust power of these mechs where the input supply voltages are out of range, similar idea to a High Tap tab on other EMs. There is a specific section in the back of the service manual describing this, actually the whole service manual is really useful for your machine.

This thing, near the transformer.


One caveat if you only supply 28V is that lower down the schematic at 16E the BANK coil is connected to the 30V line. This may be a mistake on the schematic so worth checking the physical wiring.

This would have an AC transformer originally, I'm not sure what effect if any supplying DC will have and re-rectifying through the bridge rectifier arrangement. I've read about people rectifiing to DC for individual mech's (knocker typical) to increase power.

Good luck with the project

I think that BANK coil will be a large one so needs a bit more power.

 

[Rpearsonx]

This is all slowly starting to make sense to me now thank you so much for the help everyone!

@astyy It’s nice to know I’m not alone I totally missed the voltage adjustment and that’s help a lot thanks, I kept looking up near the rectifier for that area!
I’ve had a look in the machine and the “Bank” at 16E does have the slate wire from 30v attached to the big coil to reset a bank of relays, I could rewire it to the 28v if this would still work fine?

 

[AlanJ]

can only try it. it won’t break it.

 

[Rpearsonx]

Very true, I’m just feeling a bit hesitant as I’ve never replaced a power supply before.
I think that answers all questions about the Volts/Amps and so I guess I need to find somewhere I can get the right power supplies from for a good price if anyone has any suggestions?

There's a very Gottlieb look to the schematic, could that be a pointer? Though the addition of a rectifier for the solenoid power had me thinking Williams at first.
