More cabinet and board work. The power supply board was removed from the machine and rebuilt. One BR had been changed in the past, so I replaced both with new ones. I replaced the diodes and the 25 Ohm 5W resistor which measured out of spec. I replaced the fuses and gave it a good clean.
Mounted on the plate and connected to the transformer.
Finally installed into the cabinet. Prior to testing, I set the jumpers to 240V and installed a new power cable and plug. I tested the voltages (without load) and they are in within spec. The lower cabinet is basically completely done exept a couple of repairs which will be covered later.
The headbox
I previously removed all the wiring, cable manangement and brackets. All the connectors are checked, and none need to be replaced. The entire internals are washed (even the PCB standoffs!). Here's a picture of the empty head cleaned.
The front section is also cleaned. I removed the display brackets and clean them properly, screws and hardware are buffed. I'll replace the globes later - I leave the old globes in place to prevent water etc from entering the sockets.
So here is where I'm at. The Power supply board and solenoid driver has been rebuilt. The displays, lamp driver, MPU and S&T board are next. All the boards are in EXCELLENT condition, so not much will require total rebuilds.
Slow progress, but it is bloody cold in Melbourne !
