Heathkit Model PS-4 High Voltage Power Supply: Part 1, First Look And Check Over

I got a new piece of test gear, a Heathkit model PS-4. I could not find a manual for it, but was able to find a manual for an IP-32. I looked the IP-32 wiring diagram over and compared it to the PS-4 and only found one difference, the size of the fuse. I looked at the part numbers of the transformers and they are exactly the same. The other difference is the front panel decal, other than those two things they are the same. Thank you for watching and leave a comment down below!!
