Hey Ian, thanks for all the help and inputs.

What about a 1000uf/35V ELNA Cerafine. Or go back to two caps and use ELNA Cerafine 470uf/63V. Their is a 1000uf 50V (FK Series) Blackgate on Partsconnexion, but that puppy is $25. Parts connexion also shows 470uF 50V but they are standard grade.

The 35V Cerafine should be 'fine".
Cheers,

You have to be careful with all those right-angled wires. The electrons can get all confused and decorrelated after they skid around that corner at high speed. They can even fall out, making a big mess. At best, they end up all dizzy and bump into each other randomly.

Seriously, that's very neat work and clearly took a lot of planning and preparation effort. Well done!

Hi raidprotector,
Yes, I was going to post that it looked much like a refinery. Complete with cracking towers!

It does look neat, good job indeed. Time to sweep up all those dazed and confused electrons.

Try it anyway, we can figure out what you're trying to say.

Hi raidprotector,
Your English is fine, or at least I think I understand you fine.

We we joking about your neat construction. Don't worry about this now. You are doing fine.
