Have you searched the BAMA (Boat Anchor Manual Archive) for the manual? They have the manuals for most test equipment of that vintage.

I could scan mine if no one else comes forward. It’s currently stored at my parents’ house and the next time I will be there is in about two weeks.

I looked everywhere and have had no luck. There was a member on ARF that had posted one that he drew out but his website in now dead.

That was me. My ISP dropped personal web storage a couple years ago. Here's the schematic I drew of my unit. As far as I know the Beltron didn't come with any useful paperwork other than the instructions that are glued to the pouch on the lid. All the paperwork that came with mine is advertising for how great the Beltron is.

Thanks Sean! from a Heathkit IT-5320 user, the schematic looks very familiar.

I wasn't familiar with the Heathkit unit so just had a look at the manual. It appears to be a more thought-out and higher quality version of the Beltron. Having the selector buttons instead of moving a plug from one socket to another would be nice. Also, the Heathkit has a transformer instead of just rectifying directly from the line.

Thanks Sean.
Looking at the schematic there sure isn't much in there. It wouldn't be that hard to build one. I think there is more to my old B&K 400. |

I'd at least like to borrow a Beltron. Epay prices are silly and they're usually missing the sockets....
I wanna try zapping that 17AUP4 (17AVP4?) in my Radiation King before I declare it dead |

I noticed that the original jpeg of the schematic I uploaded was pretty small. I converted it to pdf and added it to my post above to make it easier to read.
I was going through my information and came across the patent for the Beltron. It's available online: https://patents.google.com/patent/US.../en?oq=3641391
