Hello... looking for some feedback (pun intended)
Although I have owned plenty of tube amps. My knowledge of tube themselves is really limited. Other that what I have read.
I have a 60 watt 1990 Fender Super 112 amp with original:
2 x 12AX7 - pre amp tubes
2 x 6L6gc - power tubes
I love this amp and it sounds great. It does have a hum powered on with or without a guitar plugged into it. I have taken the amp to other power sources and it still has the hum with proper grounding. Other than it being painfully heavy and loud the amp has no issues. I know the red knob Fender's have had a bad rep but this amp is special... at least to my ears.
Is it possible the hum would disappear if I swapped out the tubes?
The amp has a fixed bias... would I just install the tubes without adjustment?
What band tubes should I buy? I have looked into it and there are so many choices it's confusing (almost as bad as pickups).
Would there be any benefits to replacing the tubes anyway?
I play mainly Allman bros/country rock/classic rock and blues... no overly distorted metal. It I had the cash I would definitely take the amp to a professional but I'm out of work right now and would like to handle it myself if possible.
Thanks
