    Thanks for making this video, I have the same amp - it must be nearly 20 years old and probably needs a new valve but I didn’t know where to start. Great instructions!

      Hey! I'm glad it has helped you! It's amazing how a simple tube replacement can give you back the nice tones it had when you first bought the amp. Gives it another decade of life! :)

    awesome! I have this same amp bought in 2002 - probably needs a new valve!

      Try the Glass-Tap Trick and listen if the tones sound flat or echo-ey (not reverb).

      Thanks for the comment! It you’re planning to use a tube coming from a mesa boogie, just double check that it’s 12AX7/ECC83. I think they’re using the same tube but just check before replacing taboos Mis-match

    Very helpful video, thank you. What did you use to clean out the dust inside the amp assembly (Not the pots). Do you suggest compressed air ?

      Thanks! Glad it helps! Compressed air should be good. I've used cotton buds with Isoprophyl Alcohol for hard-to-reach areas.

    How old was your amp? I've bought mine year ago but it was second hand, wonder if it needs tube replacement too

    • @CreativeEngineeringChannel
      @CreativeEngineeringChannel  3 ปีที่แล้ว +1

      it was handed over to me by a friend. He had it for almost a decade, kept well speakers are still great. The only noticeable flat tones came from the busted tubes. Scratchy knobs were easy to clean. Now she sounds great like new! :)
