The turret board and components
Well, I came close to getting all the components soldered to the turret board today. Unfortunately, I miscounted and did not order enough .022 mf capacitors (needed 7, ordered 6). For this project I decided to go with slightly higher quality components, so I was using Solen fast caps for all but the electrolytics (which are Sprague Atoms). I have other caps here that I could pull from but I really don’t want to mix brands. I’ll just have to wait until I get the last one in. That’s what I get for not ordering a few extra to begin with!
Here’s what the board looks like with everything except the one missing cap:

For comparison, here is the board on a 1964 B15NC:

Any specific reason why you didn’t use solen all around? esp. with that 600V 30uf cap in the b-15 power supply, you could use the 630V 33uf solen cap.
No, I didn’t specifically avoid using them. Since this project was a first for me, I wanted to keep some things simple, so I didn’t want to have to deal with moving the filter caps inside the chassis. The filter caps on the B15NC schematic are called out as 40/40/20/20 @ 500v. Since I could still get a multi-cap that met those specs, I just decided to do that.
