R1 = 1.2K R2 = 180 R3 = 10K R4 = 1.8K. The circuit at right is the result of our design efforts. 4.7uF capacitors were use for input and output coupling and slightly larger or small values could be used satisfactorily.
Dynamic noise suppressor, phono pre, two eq controls, visual feedback of high and low frequency drive, variable metering, tons of input switching… talk about the kitchen sink. A 'cascode' preamp which features very high gain and defeatable compensation for phono cartridge.

Their arrogance is actually bewildering. Designing a great sounding phono preamplifier is no simple task at all. The reality brings out a shockingly sobering state of the affairs. Most phono preamps just don’t cut it. As a rule, phono stages brings the noise down to a remarkable specifications being presented.
The preamp is tube-based, using two 12AX7 tubes and a 12AU7 in the line stage (which provides 14dB of gain) and two 12AX7s and a 12AT7 in the optional phono section. On the back of the fully loaded HP-100 are seven single-ended line inputs, a tape loop, a moving-magnet phono input and two sets of single-ended outputs.
Archived from groups: rec.audio.high-end (More info?) Hi all, I am about to build a phono pramp and wanted to have a few designs to look at for ideas. Anyone know of a high-end schematic or circuit description on the web that does not use the common receiving tubes such as 12ax7s etc.. I am...
