Title: Looking for Resistor array. Help !! Post by: Claiker on September 27, 2013, 06:05:51 AM Hi.
I am looking for a resistor array o equivalent, (Troyan bootleg 2ยบ pcb position F6). (http://s2.subirimagenes.com/otros/previo/thump_8636006resistencia.jpg) (http://www.subirimagenes.com/otros-resistencia-8636006.html) Thanks.

Does anyone have this game or similar and can tell me if you have any other references? Thank you. Title: Re: Looking for Resistor array. Help !! Post by: ramegoom on October 02, 2013, 01:02:40 AM If I had to guess, I'd say it's a straght-forward 1000 ohm array, one common pin, eight separate 1K resistors. Since it's 9 pins, and there is a "102" in the part number, you could easily ohm it out to see if the common pin - Pin 1 - measures 1K from that pin to the first un-broken pin. Then you can verify that there is no continuity between all the other pins. This would confirm the common rail on pin 1 feeding the eight elements.

I removed one from a bootleg capcom, the game works perfect. thanks again. Title: Re: Looking for Resistor array. Help !! Post by: KirkLasVegas on October 08, 2013, 06:50:30 PM These are known as a "pull up array"
Like it was said before, they are typically x number of resistors all tied to one common pin. If you need one and can't find the "Real deal"...simply remove the old one. Place a single resistor on end in each hole. At the common pin use a resistor lead standing on end. Cut all the leads so they are about 1/8 of a inch taller than the body of the resistors. Cut the bare lead so its the same height.Gently press a piece of "Solderwick" down on each of the leads and solder into place. While it's not as pretty, it does work 100%..... Kirk |
