I have a few rod Coleman power supplies to build and try out, they are supposed to be nice.
Congratulations on your project, it looks like a lot of fun.
I have just finished building a pair of the Rod Coleman power supplies for use on my Supravox 215s. They replaced a pair of Mastech1505D lab supplies that I had previously modified.


The Coleman's are a significant improvement and I am in the process of building a pair to try on my WVL bass drivers


I am currently powering my bass drivers with large HP Agilent power supplies, so this will be interesting.
