[Harp-L] The Twin Red Knobs

[Riccardo Grosso <rick.grosso82@xxxxxxxxx>]

Hello HARP-L friends!
Hope  y'all  are doing ok. The other night, playing at one of my gig, I've noticed my THE TWIN RED KNOBS didn't sound so
good as it used to. It didn't sound loud at all and keep on doing the feedback. I'm wondering what it can be. I know for
sure  I gotta change the tubes (pre-amp and power tubes). I checked the BIAS and I couldn't turn to 0.4 as it should be,
but it stayed on 0.2 as maximum level. Now I got few questions:

1. What kind of pre tube do you suggest me?
2. What kind of power tube?
3. This "low" BIAS level depends on the fact one of the three power tube I had on the amp was gone?

My  sound isn't so "old style". I love Paul Butterfield tone, maybe with a little more distortion (like Mark Ford) and a
LOT of basses like Charlie Musselwhite, just to give you some references.

I know you are gonna give me good suggestions! THANKS
