Jensen Cascode Mic Pre
« on: November 30, 2007, 08:55:32 AM »
Anybody here build this pre? It is on their site under schematics. I just noticed that I have all the parts for this guy layin' around on the bench. Well, except the input transformer but i think I will order a Jensen to keep it in line with their design..plus i don't have a pre with any Jensen's, just Cinemags and Lundahls.

Cheers,
Ray

I'm intrigued by cascode topology. It's like an exotic food I want to sample, but can't quite justify a whole outing for.

This one (as054) has an interesting note about direct coupling to a 12BH7 output driver stage, shown in as021.

I just pasted the two together, and it looks like a drunken "Ring of Three" seeing all those tube symbols in double.
