I believe that the triode setting will enhance the mid-range whereas the UL is more linear in freq response. That may help you to know what to listen for. There again, this is the theory.
Tube Amp settings: Triode vs UL; 8 ohm vs. 4 ohm ?
Hi. Advice please. EL-84 tubes. Cary Rocket 88 tube Amp. Klipsch Forte 8 ohm speakers.
I can Triode Class A this amp, or A/B it on UL?
I also am blessed with switches for Ohm: 4 or 8?
Speakers efficiency is upper 90’s db
What is the decision process for settings?
