Adding A supply to this B Battery Eliminator

Just grab this off google.
1a  don't understand it's 5K (pot) trim pot is fine saw some for under $1.
2  Since you already have the 4000 series diodes I'd just use them. They are good for 1a the last number determines the voltage rating. 4001 is 50v the 4007 is 800-1000v.
3  value isn't particularly critical should be ok.
4 yes
5 The 240 ohm can be a 1/2w there's not much current flow there it's passing thru the regulator. The 1K I just did a quick rough calculation abt 5w

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
