Problem Phoenix Nova Apparate GmbH Wallgerät - wall mount

[b1ffb0ff]

I recently acquired from another UKVAC member the above.

• Game: Phoenix (original installation)
• Distributor: Nova Apparate GmbH, Hamburg
• Country: West Germany
• Date: approximately 1980–1982
• Cabinet type: Wallgerät" purpose-built, compact wall-secured commercial cabinet

It did not come with a wall mount bracket so i got one made for £120.00 out of 3mm steel, they also painted it. I am now looking at setting up a credit method. And the speaker just ain't loud enough for my old ears.

Coining up
I can see the mirco switches in the coin shoot. I can piggy back off them. Not checked but assume it is either NC or NO. I was thinking of using a simple IR circuit to set up a small TX and RX in the mouth of the coin slot, so that when you put your thumb over the slot, IR reflects back and triggers a NC / NO pulse. I would liek top pulse it so it can coin up x 10 times. So, if i was to create a logic circuit to switch this on and off, any ideas on the interval time to give it time to register please?

Speak up i cant hear you...
Secondly, the pot on top right of PCB is fully clockwise so i assume max volume... So... would like to move the the old speaker and connect that output to a small amp input and put a bigger speaker in. Any recommendations here please?

Cheers

John

Going to try one of these light dependent diodes first, behind the red transparent plastic, if it works, look at some sort of leading edge relay.

Idea being io place my hand over the coin slot, lack of light coins activates relay and coins up.
