Gold Lion KT77s are a real winner IMO and won’t break the bank. Very balanced from top to bottom with good slam and detail; I haven’t found better as an EL34 type replacement.
Basic EL34 and 6sn7 tube recommendation.
I have a Mystere IA-11 tube integrated amp from sister company PrimaLuna. I bought it preowned and like-new 1.3 yrs ago and enjoy it immensely. It is outfitted with Electro Harmonix EL34 and 6sn7 tubes. (Upscale Audio is the US distributor of Mystere and PrimaLuna and also an EH supplier.)
Everything is fine currently, so I enquiring if I should replace with the same EH tubes when it's time, or should I use another moderately priced brand. I have no inclination to compare and roll tubes looking for the best match. Just looking for a good solid recommendation to plug and play.
On another related issue, my amp has Primaluna's auto-bias circuitry that automatically adjusts the tube bias, so how will I know when tubes are at the point of needing replacement, unless they are burned out completely. Thanks.
