Yes
If it ain't broke, don't fix it.

guess it depends on what you're building? once you figure out what you want find a production model similar and 'borrow' from the prior art
folks smarter than i suggest designing the power supply first and then working backwards from the output to the input. unless I'm trying to use something I've already purchased (happens a lot as I'll salvage iron from various sources) i like to have a schematic sketched out before i even purchase anything

Looks like a plexi 50 will be the next build.

I have said on here before I am just a hobbiest builder....I build amps somewhat like you guys breadboard. I don't play guitar well so i build an amp and let a friend play through it then we decide if it's something worth furthering. I just like tinkering with electronics. My friend is an accomplished guitarist and a "Marshall snob" so I like making him play through other designs.
Like many of you I have amassed  quite a bit of components for building and sometimes build and then just deconstruct it and use the iron for another project...and I haven't built anything with EL34's yet so I figured I would try..anyway thanks to all you guys and your help.

So I have 2,  360-0-360 transformers. I am thinking with SS rectification they should work for me.

I also have a 320-0-320 just incase.
