I looked up the typical current draw per slot on 500 series stuff, and most makers supply about 250 mA per slot. Some modules more draw a little more, some a little less. So I would think  a 300 mA fuse would be fine. It will hold 300 mA all day, but trip at 600 mA.

Absolutely !
Take some 1/4w or 0,6w or whatever you want.

I'm getting ready to put the finishing touches on my 610 build.  I'm adopting the below power supply from the LA2A I never built.  The power transformer is 500vdc at the secondary.  I just want to make sure that the B+ won't be too high.   I know the voltage will drop a bit under load but not sure if it will come down that much.  I haven't connected the B+ yet as I'm going to triple check all of my connections.

Maybe I should use a different power supply design...?  Just not sure where to look as the 610 schematic doesn't have much to reference from.

Thanks again for the help here.  I'll be sure to post some photos tomorrow or next once I get it working.

I’d be in.

Does this schematic indeed exist? It is nowhere to be found on the Internet. The block diagram of the 33114 exists, but that is not a schematic.

If you use the dropbox link above, the 33115 schematic covers 90% of the 33114 circuit.
