Feedback, presence and resonance....again I've built a Bassman 5F6-A clone, well almost   I had only one input so I paralelled the first   triode a'la Chieftain with 100k plate and 1k5   at cathode and bypassed with cap, I used the   bright cap and attenuation grid resistor 270k   I rewired the tone stack D-wise which I think   gave me more control over the sound.   Now I have two questions   The original circuit uses 27k from the 2 ohm   tap and a 5k pot with a 100nF cap, I have   2,4 and 8 ohm taps and use the 8 ohm tap   I tried to solder the feedback to both the 8   and the 2 ohm tap and it squealed a lot, what   values shall I use.   If I instead wanted a Resonance pot what   values then.   I'll post a schematic when I've downloaded   a more fresh version of explorer.   Thanks
