The Sovtek Corporation produces a range of the most popular audio and guitar valves.
These valves are made in Russia to high standards at the reflector plant.
These valves are used by original equipment manufactures the world over for their sound quality and reliability.
The Sovtek 12AX7LPS the first choice of many audio manufactures as it is renowned for its warm vintage valve sound which rivals the long plate Mullard and Philips valves from the late 1950s.12AX7LPS Sovtek has a long 17mm plate with a spiral filament which allows use with AC connected Heaters. This valve is a medium to high gain double triode with long structure anode plates and was designed to give a superbly vintage valve sound. Warm detailed midband with excellent and clear top end and well balanced overall sound is the reason that this valve is first choice in many audio amplifiers. It has also proved a good choice in guitar amplifiers running clean and reverb driver positions.
Audio Application
This is what the 12AX7LPS was designed for and many customers worldwide want the vintage valve warmth in the midband with musical clarity and definition that can only be found in the 17mm long plate Mullard and Philips valves of the 1950s era. The LPS is the closet valve to rival that sound.
Guitar Amplifiers
I would not use these in guitar combos or high gain stages this is because the long plate structure is susceptible to the vibration and excessive microphonics. I would only use these in guitar heads with vintage voiced pre amp sections such as old Marshall Superlead heads.
For Combos and High gain amplifiers we do not recommend the use of the 12AX7LPS in these applications.
Sovtek valves are designed and manufactured with strict quality control and engineered for demanding conditions and high reliability. This valve is an audio gem
