  1. Yup, that would do it. used to play bass for a guy that gigged with one. the bar would let us turn it up to 0.8-1.1. Mesa V-Twin pedal for tone. Apocalyptically loud. 😁
  2. If you were doing it right, they got hit so hard they broke in instantly. 😉
  3. Did you notice both the lows AND the mids cleaned up?
  4. Some of them. Then you get the older-school stuff with naked paper cones and tiny motors. Few things are black-n-white. Most things are closer to 'on a scale of 1-to-10...'
  5. I'll go with 'Yes.' Whether that's due to equipment or ears adjusting is open to debate. I've definitely heard new vacuum tubes 'open up' after a few hours of use. Guitar speakers are quite well known for loosening up after several hours, I don't see why any other cone speaker should be different.
  6. Duke: I hope you meant 16K. 6K upper limit is some pretty bad hearing loss. After all the rock-n-roll and firearms I'm still good to around 14K in my mid 40's.
  7. The RCA tubes are both made by RCA in the US. Tube ID in the elongated octagon was RCA's mark. GE did the multi-line text with the dots after it.
  8. If its ABS, Actone will melt it back together, and flow down into the cracks to seal that back up.
  9. Get the titanium diaphragms for all three and then they'll match. 😉
  10. Love your work, Mr. Warren. Thank you for sharing.
  11. It might take that level of reproduction equipment to make Kenny G tolerable. Throw on some Coltrane or Maceo.
  12. If I'm remembering correctly, the 222b had slightly smaller output transformers than the c & d models. The lore says the b had nicer mids and treble, but the c had better bass. Maybe. Recently got a circuit simulator program working, first thing I did was draw up a 222c schematic and test. The preamp & tone control stage had quite a bit of bass roll-off. Found the input cap values was the limits there. Maybe I'll check out the 'b' circuit, see what it's doing there. Then again, the roll-off was quite below the bottom of a Belle or LaScala. Update: 222b is -3dB @40Hz 222C is -3dB @25Hz. this is the frequency response of the preamp circuit, set by two capacitors on the input and a minor part played by another cap at the output. Change those cap values to .0033uF followed by .0022uF and you're flat to the low 20’s, -3dB @16 or so. 222d used a slightly different circuit with fewer parts.
  13. Also, make sure the speaker baffle/face plate screws aren't stripped. They're behind the rubber sockets the grilles push into. I had a similar crunchy distortion on mine that was due to resonance of the face plate at ~200Hz. I could make the buzz happen by tapping on the right spot, and the noise came from the horn. a toothpick or two, or a matchstick down the screw hole can help patch that up temporarily. (I really need to convert it to T-nuts and 1/4"-20 machine screws...)
  14. If they're going onto a set of Belle's, 'deeper bass' won't be a concern, nor will higher power. 20wpc would bring the cops at full tilt.
  15. Probably a warped voice coil that's rubbed some insulation off a couple of turns and is shorting against the magnetic plates. Local shop could probably change out the voice coil.
