Post Subject: A truly cool solution for RIAA re-tuning….Posted by Romy the Cat on: 8/29/2007
All records, particularly from good period, were recorded at different equalization. Even the records that were RIAA marked were in fact WAY off…
How to deal with it? Running a feedback to high impedance, in the way how it made in EAR 384P, permited useing ultra small values of caps. I use variable air caps that act as a perfect equalizers… However, the variable air caps are very hard to dial-in exactly, at least the caps that I'm useing. Here I found today a solution that might do exactly what is necessary.
It is an electronically programmable capacitor. So far it is up to 14.5pF, another year and it will be larger and as soon it hits hundreds of pFs it will be perfect for LP correction. I do not know how they milk capacitates in there and I hope that capacitates do have good sound….
