I would like to take advantage of using the 6N2P -EV and 6P14P-EV as well as
12ax7 and EL84 configurations by installing toggle switches if that is viable.
Toggle switches are viable. Just use them in lieu of the jumper. And I use the 6P14-EV. Great tubes. They can be used as is.

I have been wondering about ordering another psu board.
One is good enough (since there is additional smoothing option on the baby huey el84 boards. (Just don't populate the bias part of it...it has an error in it..and you don't need it since it is already on the bhel84 pcb boards) And in that case the choke you mentioned is perfect.

Default Oh no...not another Baby Huey EL84 build.

Thanks Bas

So just to confirm as we have 3 chokes mentioned

The 10h 500ma is overkill and not needed

That leaves

The TDS 10/250 10h 250ma

The TDS 12/200 12h 200ma

Which one is the best to go for and why?

Thank you again for your time and patience.

Lee

Hi Lee,

If you use the psu board. Get the one big choke.

If you are using the boards only. Use Either of the two. You won't be able to tell the difference between 10 or 12. If all it took was to get the biggest capacitance or largest inductance it would be easy. But look at a psu as a stream. The more pebbles in the stream the more swirls, eddies and turbulence you get. Do things as simple as possible but you have to do enough.

So I would suggest to use the psu board. And then just use the on big boatanchor choke. .

Then on the board you could use a resistor where the chokes are supposed to go...to tweak your voltage.

Congratulations and two cheers.

What are you going to build with them now that you have a pair again?
