tron ps rebuild... resistor question
hey guys im starting work on my tron.. i was going to stick a add on ps adapter in here but i decided i will try to fix the original linear ms first.
I bead-blasted the tons of battery corrosion off of the power board today(THIS IS THE WAY TO GO ON THESE CORRODED BOARDS!!!!!) And after cleaning it looks much better then i thought it would. Theres not anywhere near as much acid damage as i thought which is great news for me!
Im going to rebuild it. However bobs kit doesent come with one part i know i need...
There is a row of 3 heavy-duty ceramic "brick" resistors. On my ps the one in the center is totally fried and destroyed on mine...
Does anybody happen to know the value of this resistor? Again its the center one of three, large ceramic rectangular type...
ill buy one if i have to but i have a ton of those resistors here that i got in a bulk buy, just need to know the value.
thanks guys...
fyi the debate to bead blasting corroded boards may soon start but im telling you this is the way to go. I had that board clean in 5 mins and in most spots im not even down to copper, some of the original tinned solder remains..
You do have to be easy on the trigger, not too close, take your time but man the next time i do a pinball mpu board i am so bead blasting it... i also held the board at an angle so as to minimize any direct imbedding of corrosion deeper into the traces.
On another note does anybody sell that green trace protective krap in a can? It wouldbe nice to seal this up when im done plus it would look likeanicer repair.
