Just curious if this would be a good sub for the original 1n5275a since it's obsolete. I know it has a higher wattage but this seem's like a potential sub

Yes, those Z4KE140A zeners are what I use.
BTW, you can still get 1N5275B (tighter tolerance) but they are expensive.

Yeah, I saw those. But I think the cheapest was $5 or $7. These were .36 cents each.
Ed at GPE has some.
$1 per.

Quoted from G-P-E:The Z4KE140A will work but it's a bit bigger than the original
Some of those original fitted 1N5275A are DO-7 package which is even larger.
1n5382b is a 140v 5w zener in an even bigger package. MCC and probably some other brands produce it still. It fits on the replacement SDB i make, but not sure if the original bally/stern SDB drill holes are big enough.

I like that you've used red and black wires for the C23 electrolytic capacitor - that's what I always do.
BTW, what's the voltage rating on those two replacement green polyester capacitors at C27 and C28?

The green dipped poly caps like that are usually only 100v rated based on xp.
Color does not probably mean much but the red ones are usually 400-630v and good to use here.

Yes, those look like 100V capacitors, the green poly caps rated at 400V and 630V are physically larger in size.
The schematic calls for 500V rating.

This was a kit I got from big daddy enterprise, said they are supposed the be rated for 630v on th kit, but now I'm doubting that.
Quoted from Drewscruis:630v on th kit, but now I'm doubting that.
They might be 630V, I just expected them to be bigger. What's the full code marked on them?
What are the markings on the cap?
All film caps that I have seen have the voltage rating marked on them.
Looking at the photo - the caps in the photo look to be about the same physical size as a Panasonic 0.01uF, 400V film cap (but rotated 90 degrees). Of course, that is just eyeballing it in the photo.
Can't compare to a 630V cap - I don't have any in that capacitance/voltage range. Panasonic data sheet says the 630V cap would only be about 2mm longer - so that part could possibly be a 630V rated part.
