Replace all of your nylon display standoffs and secure those valuable display tubes that are flopping around loose! 1/4-inch tall standoff. 3/8-inch overall including base- mounts tube 3/8-inch off PC board surface. Capacitors & Kits: Bally/Williams WPC Power/Driver Board Replacement Filter Capacitor: $9.95 ea Part # WPCCAP Replacement for filter capacitor as used on Bally/Williams WPC (1990-1999) power/driver board. Rated at 50vdc DC 15,000uF. Replaces original lower-rated 35vdc 15,000uF capacitor. Higher voltage rating on this new capacitor helps extend the life of the unit, while retaining a managable size very close to original specs. Replaces such common capacitors as C5 and C11 on the earlier WPC boards, which usually fail along with their associated bridge rectifiers (see below for replacement rectifiers). Also replaces other similar filter caps on older and newer boards as well. Requires soldering skills for installation. We also recommend installing jumper wires on back of board for the capacitor leads, over to the associated bridge rectifier, for more reliable connections between the two components. NOTE: Can also be used on many other makes/models as general power supply filter capacitor. Gottlieb Lamp Power Filter Capacitors- 35,000uF 35vdc: $16.10 ea Special Order Item - allow 2-3 weeks for delivery Part # CAP33kUF35V Replacement filter capacitor for the feature lamp power supply circuitry in late-model Gottlieb solid-state pinballs. This smaller modern unit measures only 2 inches tall (50mm), and 1-3/8 inches diameter (35mm) and replaces the old large capacitor originally used in these games. Rated at 35,000 uF and 35vdc. Solder terminals. May require different mounting in the game, due to smaller size and modern-style terminals. Williams Lamp Power Filter Capacitor- 35,000uF 35vdc: $16.10 ea Special Order Item - allow 2-3 weeks for delivery Part # CAP33kUF35V Replacement filter capacitor for the feature lamp power supply circuitry in early solid-state Williams pinballs. This smaller modern unit measures only 2 inches tall (50mm), and 1-3/8 inches diameter (35mm) and replaces the old large capacitor originally used in these games. Rated slightly higher than original at 35,000 uF and 35vdc, which gives extended life and performance over original cap. Solder terminals. Requires different mounting in the game, due to smaller size and modern-style terminals. Bally/Stern C23 Capacitor Replacement Kit: $10.95 ea Part # KITC23CAP For Bally and Stern solid-state pinballs, 1977-1985. Replaces the original filter capacitor (C23) on the solenoid board, which filters power for the 5-volt logic power supply. When old capacitor starts to fail, it can cause the game to reset or lock-up during play, or cause game to not start up at all. Common replacement part in these vintage games, and a MUST for reliability. Best to replace before problems start! We replace these on ALL older Bally and Stern games that come through our shop. Kit includes capacitor and nylon tie-wraps for mounting, just like original. Requires soldering of two connecting wires already on board. Don't forget to check out our recommended modifications for Bally and Stern solenoid boards, and make them while you're changing the capacitor! Bally/Stern Display Power Filter Capacitor- 150uF, 400vdc: $17.39 ea Part # CAP150UF400V Replacement filter capacitor for the score display power supply circuitry in early solid-state Bally and Stern pinballs from approx. 1977-1985. This capacitor mounts horizontally at the top of the board, just above the high voltage regulator circuitry in the top left corner. If your game has weak or "wavy" appearing display digits, replacing this unit is usually the cure, and allows the game to better filter the power that is supplied to the displays, for more steady, reliable operation. Most larger electrolytic capacitors like this will dry out over the years and as most of these games are 20 to 30 years old at this point, most original capacitors are long past the point of needing replacement. Replace and rejuvenate your displays with a new filter cap today or grab one for a valuable spare! Replacement unit may differ slightly in size, compared to original manufacturer's parts. Williams L6 & L7 Sound/Speech Capacitor Replacement Kit: $12.95 ea Part # KITWMSL6SND For Williams pinball games Level 6 and Level 7 systems that use the sound and sound/speech boards as used in games such as Alien Poker, Blackout, Black Knight, Firepower, Gorgar, and more. This kit includes all 5 new electrolytic capacitors to replace the old aged originals on these boards. Helps clean up static, noise, distortion, and hum- all common symptoms of old-age parts in these games. And a MUST for reliability. Best to replace before problems start! Requires minimal electronics skills and tools- some soldering and desoldering of each capacitor. Switch Capacitor: 25¢ ea Part # CAP047 Replacement for disc capacitors used across switch contact points on early Bally and Stern solid-state pinball games (1977-up). Can also be used on other makes/models that use similar design. Most original capacitors will go bad and short out after years of use, which can cause intermittent operation in the game, or no function at all. Old dying capacitors are often the cause of erratic switch problems, or "phantom" switch closures, where the game acts like the ball hit a switch but it really didn't. Great addition to switch contacts if your original disc capacitor has fallen off, or was never installed. Improves performance on devices such as pop bumpers, and targets/rollovers that often get only brief (and often undetected) closures by fast-moving balls. Capacitor for Bally/Stern Solenoid Driver Circuits: 75¢ ea Part # CAP002 Surplus item- replacement disc capacitor as used on Bally and Stern solenoid driver boards in the main driver transistor circuitry. Rated .002uF at 1KV. Rectifiers & Diodes: Power Rectifier- 25 amp, 200v: $6.00 ea Part # REC2502W Standard replacement rectifier for most pinball games- old and new models. Rated at 25 amps, 200 volts, with wire leads. Measures 1-1/8" square, 7/16" thick metal body. Can also be used as replacement for 25 amp lug-lead rectifiers as used on some early Data East games. Exact replacement for the commonly-failed BR1, BR2, and BR3 rectifiers in Bally/Williams WPC pinballs (1990-up). Can also be used on earlier Williams System 3,4,6,7,9,11 and Data East power supplies, early 1980's Bally power supply boards, as well as Gottlieb System 1, 80, 80A/B and System 3 power supply units. HINT: Replacing a failed BR1, BR2, or BR3 rectifier on a Williams or Bally game? Good idea to replace the filter capacitor at the same time- see above for replacement capacitors. Use some new heat-sink compound as well (below). Power Rectifier- 35 amp, 400v: $7.95 ea Part # REC3504W Same unit as above, but higher current (amperage) and voltage ratings for heavy-duty applications, or heavy-duty replacement for standard 25 amp rectifiers in most makes/models of games. Rated at 35 amps, 400 volts, with wire leads. Power Rectifier- 10a, 200v: $6.79 ea For Bally and Stern solid-state pinballs Part # RECVJ248 Type VJ248- as used on fuse/rectifier board on early Bally and Stern solid-state pinball games (1977-1984). This modern replacement is built better than old originals from 30+ years ago, and will outperform and outlast originals. Rated at 10 amps, 200 volts. Wire leads. Measures 19/32" square, 1/4" thick composite body. This new replacement unit is slightly thicker than original factory VJ248 rectifiers by about 1/16" inch. If installing a new replacement with originals still on the board, you can add a washer to the back side of the thinner original rectifiers to increase their overall thickness, and allow all three rectifiers on the board to continue to make proper contact with the aluminum bar on the back of the unit which acts as a heat sink. Don't forget heat sink compound (below)- necessary for proper heat transfer from rectifier to metal chassis. Proper dispersion of heat helps extend the life of the rectifiers in these games. 1N4007 General Purpose Diode: 25¢ 15¢ ea Part # 1N4007 Type 1N4007. Also replaces 1N4001, 1N4003, 1N4004, and 1N4005.
