I'm having a little issue with a 90400 in my SID. The original PS was blowing the 18V (line) fuse on the transformer block so I robbed the PS I just rebuild in hope of getting my SeaWolf up and running.
The robbed PS has a BR cap kit as well as the VR and the the 2n3055 replaced. In the Sea Wolf the PS wouldn't give me a steady 5V...when testing it would walk about .5V from say 5.3 to 5.8
After rebuilding the PS it never made it back to the Seawolf. So now the PS has the exact same problem...
The voltages walk (+5, -5 and +12) about .5V and adjusting the pots have no effect on any of the voltages...basically the pots do nothing. I did ohm out the POTs and they were fine. It make no different if the PCB is installed or not
The SID will sometimes boot...and sometimes not. It seems that if the game is off for a while..say a week...it'll boot fine. If it's switch off and on a couple time day..eventually it just get garage on the screen like the reset circuit kicked in. Probably the only place I have steady voltage is on the reset circuit at .25V.
Any Ideas?
