RIAA Calculator for Two Passive Filters - Tube Enhanced!!

Postby Shannon Parks » Thu Sep 23, 2010 6:00 pm

Simple, may-still-have-bedbugs program I wrote to help with tube phono stages. This first alpha release is for two passive stage design. Lipshitz all-in-one will be no problem to add shortly. Nothing groundbreaking here. Basically I use Hagerman's two stage calc and the Lipshitz calc at Kabusa, but those are for opamps - ie low output impedance and infinity high input impedance. This corrects for Rout, the following tube's grid resistor and Miller Capacitance. Makes it *much* easier to do the math quickly and I pair this along with the almighty TubeCad. Smack me if something seems amiss or if there is a much better tool out there that I've missed.

Found a couple bugs and need to re-compile. Will re-up then.
