The Sound Speech Board has been used on "Mars", "Volcano",
"Black Hole", and now "Haunted House". While this sound board
is not identical, (there have been modifications and new revision
levels to improve operation and reliability), it is interchangeable with
previous games, (sound proms substitution required). When
swapping Sound Speech boards, keep in mind that U14 (SC0I), the
voice synthesizer, has been removed from the board since speech is
not present in "Haunted House".
5. Sound Speech Power Supply
The sound speech power supply, like the speech board, was used
starting with "Mars". Originally it was individual components
mounted on a block of wood ("Mars" and " Volcano"). A PCB was
designed and used in "Black Hole" and "Haunted House".

When the replay button is depressed, the game over relay energizes.
The open contacts supplying +24 VDC and +38 VDC close,
enabling the non-controlled solenoids. The open contact for the ball
in play closes, turning the ball in play lamp on and the normally
closed match lamp contact opens, turning off the match lamp.

Notes:
In addition to the above mentioned boards, there are also five 6-digit
displays, one 4-digit display (used on all previous Gottlieb pins),
four pop bumper boards (used on previous System 80 games), and
one auxiliary lamp board which is identical to the ones used in
"Black Hole", "Volcano", and "Mars", except for the value of RI 3
which varies from game to game. The entire board set in " Haunted
House" is interchangeable to varying degrees with previous Gottlieb
pins and should aid in troubleshooting any failures.
OPTIONS/ADJUSTMENTS
There are thirty-two dip switches on the control board to set various
options. In addition to these, there is another switch bank with 8
switches on the sound board. Many problems can be traced to
improper switch settings (i.e. game has no background sound - switch
5 on sound board is oft). See "Haunted House" game manual for all
options and adjustments.
Audio. The volume control is a 100-ohm, 2-watt pot located on the
right, just inside the coin door. There are also trim pots mounted on
the Sound Speech board. These pots have been factory adjusted.
Proper calibration of these pots requires an oscilloscope.
Speakers - 2. (4 ohms/ 3 watts each.)
Voltages. Only one voltage is adjustable. +5 VDC (500-ohm pot
on power supply) .
SELF-TEST/BOOKKEEPING
The standard built-in self test and bookkeeping exists in " Haunted
House'!. Depressing the momentary push-button switch on front door
advances bookkeeping steps # I to # 15 and diagnostics # 16 to
#20. Keep in mind that not all coils energize during self test.
(Soler.oid 2 as labeled in game manual self test description will not
energize in test.) Also, the coin lockout, game over, tilt, and U
Relay all energize during lamp test.
A built-in self test also exists in the Sound Speech board.
Procedures for this test vary from game to game. (See "Haunted
House" game manual page 18 for more detail.)
Using the self test procedures to isolate a problem (switch,
solenoid, lamp, or audio) is essential when troubleshooting a pin
game as complex as "Haunted House".
RELAYS
. There are four relays mounted in "Haunted House" . These include
the "Q" (game over), the " T" (tilt), the "U" (lower playfield
enable), and the "K" (tube kicker).

The tilt relay will energize when one of 3 normally open tilt switches
is closed. When this occurs, the +24 VDC and +38 VDC contacts
open, disabling all non-controlled solenoids. The closed contact for
general illumination opens, disabling all playjield lamps and the
open contact supplying AC voltage to the tilt lamp closes, turning on
the tilt lamp.
