Bally Battery Corrosion Repair Kit

Includes all the parts normally affected in the corrosion zone of the Bally MPU. If corrosion is extensive, further parts may be required. Does not include 5101 SRAM which is available separately.

£5.00

5101 SRAM. Always damaged on an old Bally MPU. Make sure to use a socket when replacing.

Bally Solenoid Driver High Voltage Transistor Kit
Includes: 1 x 2N3584
2 x 2N3440
1 x TO-5 Heatsink for 2N3440

These components provide the 190Vdc for your score displays. If they fail, then you may have no displays, or it is possible that the voltage output is too high typically 240Vdc, which will cause premature failure of your very expensive displays. Check the voltage output today, before it is too late!!

TRANSISTORS

Useful Transistor Information

TIP Series Transistors

TIP refers to the manufacturer: Texas Instruments Power transistor. Odd numbers are NPN, even numbers are PNP. The letter at the end identifies versions with different voltage ratings. No letter=40V, A=60V , B=80V, C=100V.

Other manufacturers may not use the A,B,C markings, but all devices supplied will match the rating listed.
