Sovtek 12AX7LPS Preamp Vacuum Tube
The Sovtek 12AX7LPS is a Large Plate Spiral Filiment 12AX7 tube. This is the best offering from Sovtek yet. It is used by Mesa Boogie and is also used by many other smaller manufacturers. The spiral filament reduces hum in AC filament amps - while the larger plates allow for a more linear response. This is one of the finest modern production 12AX7 being made today.Compare with other tubes here.

Probably the best phase inverter tube available today. Stable powerful signal pumping the power tubes allowing them to produce the full tonality they were designed to deliver.

There are some great 12AX7 tubes to choose from and this should be on everyone's short list. My opinion this is the best tube for the gain/phase inverter position.
