I desperately need some recommendations for a high gain, low noise fet for a phono stage I'm pulling together.
Its made up of 2 linear gain stages, with passive eq. The gain stage topology is essentially a very simple triode type circuit. (Yep, you read that right). With just 1 device in each stage.
I'm trying to achieve extremely high MC gain (good enough for low o/p Ortofons, etc) and I'm just terrified about ensuring that in particular, the first stage is treated with the care it requires. (Hence my search for a high gain, low noise device).
I understand Toshiba fets have a decent sonic reputation . Any recommendations anyone? (Toshiba or anything else)
😕

Fets
The Toshiba 2SK170 or 2SK389 (dual). The 2SK147 is even lower noise but not in production anymore. (nobody is getting any of my stash) For more info:
