Reviving a parted out SL74

[Nugepb]

I purchased a parted out SL74 a few months ago in hopes of bringing it back to life. The hardest part was tracking down a solenoid for it and I didn't want to buy a used gun just to part it out.
Instead, I designed a manifold for it to use a LV1.6/LV2 solenoid and gasket. The only tweaks I made to the solenoid was sanding down the screw retainer slots and screw heads for it to fit the frame, as I didn't want to modify the frame in any way. Also, I designed a voltage regulator circuit to drop the output voltage of the ego board from 5V to 3.3V and added JST connectors to make it plug and play.

I don't have shooting videos of it yet, but I've had it ramping at 15bps with no issues. Currently, it's set to 10.2bps for local play.

I've added a black SL3 reg, feedneck, and pops asa. I couldn't track down any reasonably priced QEV's, so instead I added some banjo barb fittings from McMaster-Carr. Next, it'll be off the anno.

Let me know what you guys think of it. I have two manifolds and a few voltage regulator boards left, but I can get some more made if there are any interest.

Good work!

I didn’t realize the new LV solenoid used a 3v pilot.. good to know

Would you consider selling the voltage regulator and manifold as a kit? There are lots of older egos currently relegated to paperweights because of solenoid issues. I would buy a kit for sure.

Oh wow. This is really great work.
The SL74's are so fun. Really love that era ego.

I think I may have seen that up on ebay? Too bad the seller took the ASA.

I would love to get one of your custom manifolds and regulator boards. PM sent <3

Yeah for sure. I need to get barbs for them first.

I am pretty sure my old ego 7 still works, but I'd also buy a manifold just to have back ups.

[Frmrspec]

Also that manifold will work for the etek solenoids which will save you about $100 or even more because you can find them used

[Nugepb]

Probably not. Screw hole locations are different between the two.

[Nugepb]

I have one manifold and board left on hand, ready to be shipped out. PM me if you're interested.

[BrickHaus]

So, the new solenoid, does it have metered flow valves on it? I'm just wondering if you ant make the ego 7 smoother with this change.

[Nugepb]

It does have the valves on it but I feel like it acts more like a QEV.

Hey, I actually joined MCB just to talk to you. Got an ego8 I'm reviving after not playing 10+ years. I replaced all the orings and the reg seat. However the manifold on the solenoid is f'd / leaking air as of yesterday, and I can't get the retainer clips out to replace the orings on the barbs.

Is the manifold/voltage regulator you made for the LV solenoid still available?
how much?
What would I need to use it? Assuming the actual solenoid and a gasket? Or would I need another set of wires to hookup the voltage regulator to the board itself?

Nugepb ... I can't reply to your DM but thats a deal... dm me where to send the paypal to

Edit: ...we'll get started on it and I'll pay... just need to wait for the MCB 10 day timeout to DM the address (which is US Maryland)
