Hi Jesder
welcome to the pinside-forum. Yes, in this subforum we talk about "a specific pin has one (or 2 or more) specific problem / fault".
Writing Your post-1 You made a mix of information and questions.
Great, you have a schema - do You also have a manual ?
One (big) problem is: "Steve Young, PBR, USA" has the "Rights" on Gottlieb Paperwork - he does not allow to show in ipdb Gottlieb paperwork: http://www.ipdb.org/machine.cgi?id=2255 ...
I do not know, if we are allowed to show "part of Gtb-Paperwork" when discussing "faults / problems" on Gottlieb pins.

I believe "Your main problem" is the "mode" of playing a pin. Here - http://www.ipdb.org/glossary.php#Add-A-Ball they say "a TRUE Add-A-Ball pin" has the Backglass with the text "Balls to play" - Your pin is a true Add-A-Ball pin: http://www.ipdb.org/showpic.pl?id=2255&picno=63818 (here the game starts (counter is Zero) on the fifth ball -> You loose that ball -> ball-4 -> ball-3 ... ball-1 -> Game-Over.

Novelty Play: http://www.ipdb.org/glossary.php#N -> A "True Add-A-Ball" from Ball-5 down to ball-1 -> Game-Over - You may make millions of points / get EVERYTHING on the playfield --- You will not be rewarded (no payout / No Replay(s) by the counter / No Replay by a Special / No Replay by Number-Match-Unit / No Extraball - simply NOTHING).

Many regular pins can (also) be set to Novelty play - the only difference to "a true Add-A-Ball-pin set to Novelty-play": A regular pin set to Novelty play: It starts showing Ball-in-play-1 -> ...-2, -> ...-3 -> ...-4, -> ...-5, -> Game-Over.

So playing a pin in Novelty play: YOU must reward Yourself: Take along a piece of paper and note "Personal-High-Score-Points (example) 87430" and "Personal-High-Score-in-playing (example) 4 Minutes and 35 Seconds for 5 balls (played)".

You must study carefully the schema: where are Jones-Plugs drawn in the schema - and what effects do result of the different Plug-ins ?
In Novelty play you might be "rewarded" with 50'000 points or 75'000 points - who cares ...

I am interested to have a look at snippets of the schema (dealing with "Jones-Plug-Settings") - I DO NOT KNOW IF YOU ARE ALLOWED TO SHOH IN PINSIDE SNIPPETS OF GOTTLIEB SCHEMA.

Question to "USA-pinsiders": what is allowed / what is forbidden ???

Jesder, if You have specific questions like "XYZ-Relay does never pull" or such: Please ask specific questions. Greetings Rolf

P.S.: Maybe interesting (?) http://www.ipdb.org/machine.cgi?id=376
To "confuse us": http://www.ipdb.org/showpic.pl?id=1314&picno=4251&zoom=1 Williams used the term "Convertible to Add-A-Ball Model" - what it means is "The well known "Replay-Pin" can be manipulated to "instead of a Replay - You only get an Extra-Ball - example (would be Extra-Ball at 3200 Points, 4300 Points, 5400 Points, 6500 Points : ) http://www.ipdb.org/showpic.pl?id=1314&picno=13946&zoom=1

Hi Jesder
I live in Switzerland (I do not want to run into problems with "US-Laws"). Here: https://pinside.com/pinball/forum/topic/gottleib-spirit-of-76-schematic -> post-4 / post-7 they say "Steve Young at Pinball Resource has the rights on Gottlieb papers" from http://www.mondialgroup.com/gottlieb.htm .

Maybe (?) You want to start a topic in https://pinside.com/pinball/forum/forum/electro-mechanical-hangout (?) - asking "are we allowed to show snippets of "Gottlieb Paperwork" ?". I would like to learn "what is allowed <-> what is not allowed". Maybe I make "a big fuzz about" - I just do not want to be sued ...

Here is a fun "True Add-A-Ball": http://www.ipdb.org/machine.cgi?id=1853 -> the player has started at "Ball-5 in play" and played good and was rewarded with an "added-ball" - still playing good and was awarded with another "added ball": http://www.ipdb.org/showpic.pl?id=1853&picno=63082 ...

Also funny (at the bottom in ipdb : ) the video ...

Jesder - can You show a picture like: http://www.ipdb.org/showpic.pl?id=1853&picno=22879&zoom=1 - of Your "Space Orbit Backglass" ?

I do not like "Novelty Play" - I want to be rewarded ...

Here http://www.ipdb.org/glossary.php#Add-A-Ball : the WOW-Feature is mentioned.

If You try-out different settings of Jones-Plugs: Have the pin in "Add-A-Ball" (in Novelty Play a lot will not be working - as the player shall not be rewarded).

I would like to help on specific problems - but I should see snippets of the schema ... Greetings Rolf

Hi Jesder
in post-1, pic-2 you show a unmarked relay - when You manually act (at several times) in game-play: do You have some effects ?

Post Time http://www.ipdb.org/machine.cgi?id=1853 has "Novelty Play Mode" "Add A Ball Mode" "Extended Play Mode" - maybe Your pin (also) has (rare, uncommon) "XYZ Mode" ?

I would like to look at snippets of the schema showing "plugs able to be pushed-in in several positions) - as an example Fun Fest -> http://www.ipdb.org/machine.cgi?id=972 - schema (I must make a copy onto my computer) -> snippets like E-12 showing (here) "Adjustments on Extraball-Feature ". "Adjustments on Special Feature". Also snippets of "3/5 Balls Adj. Jack (if existing in a ADD-A-Ball machine)", also ... how many plays per coins - ALL adjustable features (in the schema) - with wire-colours ... Greetings Rolf
