Title: stereomour power supply point to point
Post by: ee on February 17, 2016, 11:54:14 AM: Just curious if there is a photo of the Stereomour power supply board converted to point to point. I've resoldered the ps board many times and it's still good but probably at most one more time maybe none. I sometimes read pictures better than words. I am working on reading schematic then drawing it on paper like I'd be doing live and compare it to the board. This is good for learning for sure also. I'm just not convinced I've got it yet.
Thanks
Eric

If you wanted to wire a new power supply, the tougher issue will be where all the parts can fit on the chassis!

Today I did do the most fun thing though which was to successfully wire point to point for the power supply. Maybe not much of a stretch for some but it is sweet to have done it. Took me to a new level of enjoyment.
Thanks
Eric

The extra hole just below the beige 270k resistor was made because of the nut/bolt holding tag board to plastic strip being to close to transformer terminals below. I would have used nylon nut/bolt perhaps if I redo it.

Allows easy switching out of caps. Which I already did during this pic taking. Outer 2 lugs each side are jumpered together for same reason and are B+.
2nd pic is a bit more open without the bypasses in.
I had the Jensen pio electro 100uf then tried 220uf which are in the pics above. This has Vishay electro 100uf. I didn't trim the leads on the Duelunds yet until I decide to leave them. I've tried them in this location with the board but it was so so. With this it is pretty good. I also have Jupiter copper foil 1uf that I've tried before in this location that I will try again. They are longer though and the Duelunds slide right in thanks to their lead arrangement.
