SOAP MKIII (Simple OpAmp Pre) With onboard PSU

[mikesnowdon]

It sounds like it is some kind of transformer, something like you see in the link I posted earlier. Whats it got written on it?

Can I also be a candidate for a SOAP board if some more are going to be made?
Sound interesting and simple preamp, nice to have.. would do a LM4562 based one..

Thanks!

Could you upload some of the photos that were lost because they were linked externally?

Hi guys.

Here are the files for the Evolution. Main difference from the MKIII is the onboard transformer.
