Bally AS-2518-18/49 and Stern TA-100 Power Supply

Power Supply/Voltage rectifier board used in early solid state Bally and Stern pinball machines. This board is designed as a replacement for the following: Bally AS-2518-18, Bally AS-2518-49, Stern TA-100. When designing this board Big Daddy didn't just make a copy, he did his research and made improvements and fixed faults the OEM boards and other reproductions had. Not the cheapest, but this is one of the best on the market!

• This rectifier board uses top mounted bridge rectifiers with proper heat sinks, which is a design improvement over the original bottom mounted bridge rectifiers
• Heat sink grease or compound is used, not all makers take that step
• All incoming wire “E” connection holes have traces on both top and bottom of board to ensure that the current can easily flow from the connection hole
• The “E” connection numbers are silk screened on both the top and bottom of the board to facilitate wire installation
  
• Redundant E9 and E10 connections are provided for the double wires used for games that had AS-2518-49 rectifier boards. All other E connections match those used on the AS-2518-18/TA-100 board, including redundant E7 and E8 connections
• Six test points are provided at the top of the board (five for voltages and one for ground) so that even an amateur can easily measure board voltages
• An LED indicator is provided next to each of the 5 voltage test points (TP1 through TP5). The LED is on when voltage is present
• The printed circuit board is fabricated with thick 2 oz. copper and all traces meet or exceed the sizes recommended by IPC-2152 for current capacity
• A ground plane is provided on both sides (top and bottom) of the board, and extra plated through hole connections have been added to ensure that the two planes are well connected
• The negative output of each bridge rectifier is connected to the ground planes, which handles the high combined current from the bridge rectifiers
• High current fuse clips are utilized for F1 and F5. The other fuses are well under 10 amps so normal fuse clips are used at those locations. Some other makers including OEM used underrated clips
• The rectifier board mounting holes are identical to existing OEM boards
• More wording under the fuses give information about their function and when fuses can be different
• Quality name brand parts are used throughout. Fuses are quality Buss, Littelfuse or Bel fuses
• Fuse spacing is correct compared to many reproductions that can leave as much as 1/2 of the fuse not contacting the clip causing heat issues, see 3rd picture
• This rectifier board is built with readily available through-hole components to facilitate long term serviceability
  
• 2 year manufacturer warranty
• Warranty void if your game causes a failure
• Please note that header J1 on this board has 9 pins (the 9th pin is only used for Bally AS-2518-49 replacement). If your game has a Bally AS-2518-18 board or a Stern TA-100 board, then your connector will only fit over 8 pins of J1 and the 9th pin will be unused
• Connector kits are also available, see 'You may also like" section below in this listing

* SAFETY WARNING *

The procedure involves cutting or desoldering wires from the old board and then soldering the wires onto the new board! You need to take extreme care to track which wire goes where. Big Daddy recommends installation be done by an experienced technician or seasoned hobbyist. Once installed and powered up, this rectifier board will have hazardous high voltages which include AC voltages (120V or 240V AC Line, 49V, and 173V) and DC voltages (230V and 43V). Extreme caution must be used by any person who is in the vicinity of this board. Remove power from the machine before doing any installation or removal work related to the board, including soldering/desoldering and connecting/disconnecting header connectors!
