Excellent pre-amp tube at very reasonable price. Replaced original high-end tube in SWR bass amp and this tube sounds just as good, maybe even better.

These exact tubes(12AX7) are getting harder to find. Tubes came exactly as expected without using replacement model number tubes. I bought 2 in order to have a spare.

These are excellent quality and make smooth tone for the preamp section of your tube amp at a reasonable price.

This tube has exact size to fit "TUBE MP" preamplifier and works great as design. Keep in mind: all tube equipment requires AC voltage stability for better performance! Also low price needs to be mentioned. Be careful with other tubes: same number and different size!
