Jfet Doubler

[lowell]

RG,
       Thanks for this circuit... it's cool... however it wasn't loud 'nough.  I posted on Ampage.org and you suggested adding another SRPP to the output to boost it more.  I added that circuit and now I just get serious motorboating.  I searched for this on the this forum and read that this could be a power supply problem.  Should I add some RC decoupling in the power supply and what components and where if so?

Ok I put my diy preamp BEFORE the jfet doubler and it sounds great!  RG, I think this circuit would benefit ALOT from adding a gain stage to the collector output after the input splitter/buffer and before the differential.  Maybe even 2 stages....  What you think?
