Team TNA - The UK's Total Nuclear Annihilation Pinball Club

Update, 6hrs of playing, nice and hot games. TNA as usual - just one more game....

Some experienced TNA players didn't even notice the mod.

So on that note. Here you go

 
Just got some green luminescent coming in and glow in the dark next month - man that stuff is hard to find
 
Really great job you are doing with the TNA and Pulp protectors mate. I’ll be giving you a shout soon for an order 👍
 
Found another cure for sticking flippers. Core flipper starting playing up this weekend

And was amazed at the pinball olympics set up so done my own version

Have fitted the side lights but the transformer failed , just awaiting a replacement

If I can i’ll bring it to pinfest

With support from Spooky (they’re really helpful) I’ve managed to diagnose the cause of the reset being the beacon topper. Just thought I’d post that here in case anyone else ever has the same problem. With the topper power disconnected, it no longer resets.

I believe after a lot of to-and-fro'ing and testing with Spooky, we have established the cause of the resets. Just a quick recap on the issue - sometimes the beacon starting would cause a reset on its first activation after a power cycle. If it worked the first time, it never seemed to subsequently cause a reset. But either during a game, or also during test mode, it would sometimes fail first time and the game would reset. The coil board tested fine and eventually the cause seems to be... the bulb is incandescent! So with my limited knowledge of this stuff, I believe the bulb has a significant initial power draw (inrush current) and this is sometimes taking the 12V too low and causing a machine reset.

Interestingly the replacement beacon also had an incandescent, so I suspect all CEs have the wrong beacon bulbs? I imagine one could adjust the regulator as a workaround to raise the 12V slightly so it could just be that the 12V on my machine is set just slightly lower than others, but I have swapped in a 12V LED flasher and not had a reset since... although of course as it was an intermittent fault I can't be 100% sure it's fixed 😬 🤞
 
Interesting
I’ve ran both led and filament lamps and have reverted back to filament - no issues
My recent issue where the Proc wouod not boot was due to me overloading the 5/12 supply and such it wouldn’t give 5v instantly for the proc to boot. Such i installed an additional 5/12 psu

Have you tested the voltage here as maybe your supply is faulty , mine blew up in the first 2 weeks of owning my game. Hense they are not perfect

Totally disconnecting the beacon might help you in testing

Keep an eye on the blue leds on the proc when testing too. the lower ones stay on with 3v and the rotating cluster is 5v

You can adjust the output with a small screw on the psu whilst measuring the voltage

I suspect an issue with the initial supply to the circuitry or a faulty beacon cable ?
 
It's definitely the beacon - it's the initial activation of the bulb that causes the issue. Beacon disconnected = no resets. Also tried a replacement beacon so it's not a faulty one.

Supply can't be the issue as it happened for effkay and now also for me - plus, it's a very long boring story, but our supply has been thoroughly tested by Western Power and is fine.

If the regulator on my 12V line is set a teeny bit lower than everyone else's that would be enough to cause a reset whereas for everyone else that small inrush isn't causing a problem? Spooky seem sure that's the issue and also stated the bulb should be an LED. If I knew what I was doing I would test the voltages but I'm not confident enough to - I thought there would be test points on the boards like on a Bally-Williams board for that?
 
The system operates on 5v - the screen and ancillaries are 12 , the solenoids 48

but the 12/5 are from the same supply.

i can send you my number and we can check it if you like ?
 
Thanks for offering, I'm not at home right now but if I hit any more issues I'll certainly take you up on that :)
