    Hi all,

    I just bought a fender bassman tv twelve tube amplifier for a month . Don't know why , the amplifier's sound is seldom noisy and 'micro' while I plug in the bass guitar and played for 10mins later. Sometimes , The sound is back to normal when i turn it off for a few mins and turn on again. Anyone could tell me what is the problem ? Should I install the new tube ?! Big thanks !!!

    Remove the tube and make sure the pins are clean, then put the tube back in the socket.

    If there is still no improvement, then yes, I would install a new tube. "Noisy" and "microphonic" are symptoms of a bad tube.
