46+ 12Ax7 Tube Phono Preamp Schematic Pics. Schematic and music samples included after description. The overall gain of the circuit is about 150.
Ideally, every 12ax7 should yield the same today, it is by far the most common preamp tube used for electric guitar amplification and there is an almost overwhelming schematic of the preamp circuit used for 12ax7 comparison tests.
This is great news for those new to vacuum tubes that want experience… parallel 6dj8 (ecc88) line preamp. Schematic and music samples included after description. I think a good phono stage using only to 12ax7 or equivalent tubes should exist for mm cartridges. Available some notes about this schematic :
