At some point and on my list of things to do, I will be making a high output phono stage to suit those who insist on using insensitive valve amps. Such a device needs a very high supply voltage so that the signal doesn't clip. Actually it needs more than the usual 36 volts which opamps work on, and so requires the use of a ranging supply. I had thought of incorporating it into the "big Accession". I had also thought about giving each input (yes, this will have inputs for two cartridges) its own level control. Therefore it will do exactly what you're looking for. We will be happy to accept trade-ins

Graham, I had missed this discussion! If you will ever make such a phono stage, let's call it a "Reflex M+": - innovations introduced to of the Accession for the RIAA equalization kept separate from amplification (your patent, in short - no need for selectable equalization curve or "flat", though) - selectable gain (let's say 40 dB, 44 dB, 48 dB for MM) - mono switch - selectable resistive and capacitive loading via easy front switches (no rear mini-switches) - no volume pot (unless used to select the gain!) ... well, you already have a customer! |

What about an Accession (simplified) with variable output gain and switches for capacitance, mono and 2 outputs without the numerous RIAA curves. I’m not sure how much that would simplify the circuit design and reduce the costs?
