Hi,
I have a Seeburg SCH1-4 that I’m trying to convert to MP3. I just found out it’s missing the APU. I don’t care if the coin mech works as I was planning on putting it in free play anyway, but will it work at all without the APU?
If it does require the APU, can I use an APU10 even though the sticker inside says APU11?

Hi Skreien
Yes it can be made to work without the credit unit being fitted.
The plug of the credit unit plugs into a 15 pin socket lower right of the consolette.
As you look at the front of the socket the top left hole we will call 1 if you put a wire from 1 to 7 that will put the machine into a constant credit position giving you free play.
Hope this helps Cheers Scudie

You’re the MAN scudie! You must have access to an SCH manual?

Hi Sooner
Unfortunately not, had a SCH a while ago, I figured the first 12 are the same as an SC.
13 to 15 are audio.

Scudie – I’m curious. Does the volume control mod to separate the common negative between the speakers work the same for the SCH models as it does on the SC model?

Hi Steve
Yes the mod to the volume control resistor board is the same, the colours of the wires differ compared to an SC.
They also did away with the audio relay that is fitted adjacent to the volume control resistors on the SC 1-4.
It is my understanding that by routing the audio through the credit unit they stopped customers sitting in the bar / diner listening to other customers selections unless they had them selves already deposited money and had a credit on there consolette. After all they were there to take money!
On another note if the diner had say for round figures 10 consolettes & 50 % of the customers were selecting records that were current say out of the top ten, chances are that several of the customers would choose the same track, now as far as I am aware once the phono (jukebox) has registered a song to its memory it can’t remember it more than once, so it plays the song all the customers are happy because they heard there selection. The customer would be blissfully unaware that potentially all 5 of them coul have paid to listen to that specific record !
Cheers Scudie
