RCA Phono Stage Redux

Konnichiwa,

Being able to drive 10 KOhm loads and reasonable amounts of cable capacitance is all that is required.

ECC88/6DJ8 @ 12mA/90V with a 12K Anode Load gives you a gain of 29db and drives 10K load just fine. No buffer needed.

Konnichiwa,

Look, you desperatly want to throw FET's, CCS's and other "High Tech" where it is not exactly needed, no grief from me. But I think you may wish to check your calculations, just to make sure the black smoke inside Solid state stuff stays inside.

I find it refreshing to try something different to see how it turns out, and combine technologies usually not applied together, even if there are other easier means to an end. The danger is in seeking solutions to non-existent problems or in being so invested in one's own solution that one overlooks other better ones, the "not invented here" syndrome. And there is a learning curve when one ventures into the unconventional, I had one helluva time with loop stability in my CCS-loaded tube active feedback RIAA.
