Vacuum Tube - 12AX7LPS, Sovtek

$14.50
In stock

9 pin miniature preamp tube (Amplification Factor = 100). This Russian tube is full bodied and well balanced. It has a high gain with a very smooth presentation. In overdrive, it is not quite as defined as the 12AX7-S-JJ, but it offers more crunchy fizz. For more information about our 12AX7 tubes, see our tech corner article on 12AX7s.

The perfect current production tube for the phase inverter slot in my Peavey Classic 30 amp. It came highly recommended by trusted sources and did not disappoint. I'm on my third Sovtek 12AX7LPS as I change out the PI tube whenever I change the power tubes. Great tube at a great price.

A+ ! Great Tubes ! I am using these in the V3 PI stage in both my Marshall Plexi Cloan Amps (Metro Builds) These tubes work great, Where others didn't. I will be buying these again just to have on hand.

Currently using this as PI in both my Peavey Classic 50s and I'm very happy with it there. Full bodied lush tone, can really drive the output section well. Also have used it with some success in V2 (lead) position where it's quite good, but a little doesn't have enough "hair" for that position.
