Does the SE Astec PSU have a voltage adjustment?

I am troubleshooting BlueSCSI flakiness on an SE and so far it is starting to look like a power issue. I was going to adjust the voltage output but it has the Astec PSU. I took off the top case but there is no visible adjustment pot. Does anyone know if it has a down facing adjustment? Should I bother taking the board out? I cannot find much online about troubleshooting this brand PSU.

Well, I lifted the board which was not as hard as I thought and I do NOT see any trim pot for adjusting the output voltage like the Sony. Bummer. May need a recap or ATX swap. Fun project, different weekend I think. I will try one from another SE now and see if I can find root cause of my issues.

Another option would be to get another Sony CR-44 and recap it... I got lucky with my SE, in that it had the Sony supply in it. Saw a few CR-44 power supplies on the 'bay...

Yeah, a Sony is what is inside the other SE.

I haven’t posted about the actual issue. I was having some weird errors trying to initialize a disk image. SCSI utilities would see the drive image on ID0 but it would not consistently mount. I expect the image was setup with Lido, and reinstalling the driver did not help, but I tried Silverlining and it seems to be working better now.
