Here is an updated Saga on my power supply problems. Last week I originally lost power to the console but the software kept running which pointed me towards the two console power supplies that are within the CPU. First I replace the linear power supply and I thought that fix the problem but after about 15 or 20 minutes running it died again. That pointed me towards the other power supply which is the Aztec lps152 5 volt power supply. I was lucky to find to on eBay buy one seller and I bought them both up. They arrived last night I installed one and it did not work. I then installed the other and my d8b came back to life.
My question is it seems that these are hard to come by so I'm inclined to keep the other one and try to get it fixed along with my original one rather than send it back for a return. So my question is are there any other power supplies to supply 5 volts that will work in the CPU where is it best for me to hold on to what I have and try to get them all fixed. I am not thinking there are a lot of power supplies on the market that will work with the d8b's proprietary set up. Searching the internet I can't even find an Aztec lps152 model.
Look forward to hearing everyone's advice.
