I bought an isolation transformer to connect to a monitor I just bought, then when I pulled the power supply out of my cab, I noticed it ran to this silver box. Is this an isolation transformer, or what is it? |
| MonitorGuru:
THe silver box is merely a power line filter. (basically a couple of capacitors to filter out RF noise). However the power supply as you called it behind it *may* be an isolation transformer, you have to check what the markings are on it and where the wires lead to. We'd need more picturs to be able to tell for sure. |

You have a power chassis assembly from a Williams cabinet. The silver box is indeed a power line noise filter. The big power transformer next to it already has an isolated winding for the monitor. Terminals 9 (purple wire with yellow tracer) and terminal 10 (also a purple wire with a yellow tracer) are the isolated 120 volt ac output to your monitor. A Williams Defender manual/schematic set will match the wiring that you have. |

Dang, if it wern't for the cost of shipping, I'd gladly send you a plain, brand new isolation *only* transformer (only 2 wires in, 2 wires out needed) in exchange for the entire power board and wiring that you have (that you won't need if you're converting the Defender to a Mame or newer game)- --- As I have a Defender that is a bubble bobble and I'm trying to convert back to original Defender-ness! You wouldn't happen to live in ND/MN ??? :) |
