Sovtek 12AX7LPS Long Plate


Sovtek 12AX7LPS is a long plated version of the 12AX7  ECC83 and is favoured by a number of amp manufacturers for their smooth rich tone. Not recommended for the V1 position in combo amps because long plate 12AX7/ECC83S types tend to be more microphonic. We also have balanced option for phase splitter applications

Sovtek 12AX7LPS Long Plate

The Sovtek 12AX7LPS Long Plate  is a relatively new variant of the ECC83 type. It is quite a different construction to the other Sovtek types. It is a long plate valve.   The Sovtek 12AX7LPS  has larger plates inside and they have a very smooth tone across all frequency ranges. Just right for blues and Jazz in my mind.  many amps use this valve as the phase splitter.  it is not recommended for the V1 position in a combo amp because the longer plate designs tend to be more microphonic.
