![]() We are 100% compatible with the ORIGINAL Gottlieb S80,80A and 80B MPUs as well as 100% compatible with our own S80 MPUs. Also a great upgrade replacement for NTE123AP. Note: The Rottendog GDB080 driver board is compatible with ALL licensed Gottlieb MPUs. Product ID: 5A-8938 2N4401 Transistor 0.25 In Stock Quantity in Basket: None Location: K1 Qty Description 40 Volt, 600 mAmp Pre-Driver for TIP 102. Warranty is void if not installed by professional pinball technician. – Supports the Gottlieb reset/watchdog daughterboard to eliminate “lockups” – All through- hole components for ease of repair – Made from new technology parts that are easily available – Ground screw lug added to easily attach ground wires to back box/power supply – LED added to show when power is supplied to the board The transistors are in sequential order on the MPU (sans Q14 and Q18), but the fuses numbered on the fuse board. The MPU transistor positions Q1-Q20 correspond to the fuse holder positions F1-F20. – Silkscreen showing all component designators and locations Not all games use all the fuse holder slots, since each game has a different number of solenoids and transistors on the MPU at different positions. – Simplified design for ease of troubleshooting – Lower power dissipation transistors for less heat generation – Higher current carrying transistors for longer life Pictures, documents, manufacturing data, ratings, comments, features, and history for Stern 'Transformers (Pro)' pinball machine. – Higher voltage Breakdown Transistors for longer life 2N5060 Silicon Controlled Rectifier SCR Thyristor Transistor. – Eliminates the power on “Clunk” associated with Gottlieb S80 power on. Shop / Pinball & Arcade Parts / Electronic Components / Transistors. This covers all System 80, 80A and 80B pinball games and works with all licensed Gottlieb MPUs and power supplies. expander circuit.GDB080 – is a direct plug-in replacement for the original Gottlieb System 80 pinball Driver Board. Slow it down, lower the voltage.Īlso, from the other thread, yep, leaving the series diode off the coil will trigger solenoids from the other 4 pairs of the sol. The point is that the flyback voltage spike developed by the coil is directly proportional to the switching time. View at The Internet Pinball Serial Number Database () (External site) Theme: Licensed Theme - Robots - Science Fiction. This cap slows down the transistor turn off by feeding some of the rising collector voltage back to the base and so trying (in vain) to keep it turned on. We’ll need to know the driver connector and pin info, the driver transistor, color of the driver wire and the solenoid type (low power, high power or general purpose). So either the transistor is being commanded to turn on for too long (switch short/software glitch/harness prob etc.) and being heated in to failure, or its a death spike from the solenoids turning off.Įither the catch diode open circuit across the right saucer coil itself or the one across the 2nd blue inline drop target could cause this.Īlso, might be worth checking/replacing the cap across the transistor base/collector. ![]() The only high volts path is collector base shorted. That resistor has blown from sudden high volts, not slowly cooked. ![]() Medistate kavacik telefon numarasi Transistor 2n3055 equivalent Eveliina. ![]() I think the melted coil in the 'smoking fathom' thread is an effect rather than a cause and that something is killing your transistors.
