What is this about biasing? And is it relevant with this amp? See NOTHING about it in the manual
Not relevant. This amp auto biases like most modern tube amps.

I have Telefunken RFT el34’s which sound excellent. They were like 260 used on eBay. I have Sophia Electric which are smooth and musical. Also like KT77 by Genalex Gold Lion. New production out of Russia. Sound excellent also. I am finding thus far the el34’s affect tonality much more than the ecc82 tube roll does.
No. Telefunken ECC82 better with KT77s. Not stock JJ. Man! No quick a-b’s. Takes albums to figure this out! Takes time. This could drive someone insane. Yes, input tube can affect sound as much as output tubes. Double revision on what I said earlier.But I do hear differences in ECC82 s when paired with one particular pair of power tubes. I find it interesting that my stock JJ ECC82 sounds better with my KT77s than the smooth plate Telefunken does. Is there such a thing as input output tube synergy between the two sections? Such that when changing output tubes you may find a different favorite ECC82?
Oh, and I don’t like the new Russia production GL ECC82. Not nearly as good as my KT77s from them.I have Telefunken RFT el34’s which sound excellent. They were like 260 used on eBay.

Just powered down amp switch not yet power supply and heard a loud pop in left channel of my HEKse. Was sure something was ruined. Tentatively powered it back up with volume all the way down and played fine once I slowly turned up the volume. What the heck happened?!
Thank you. I hope my HEKse ok. They SOUND ok. Guess it would be obvious if damaged.Never power an amp on/off with headphones connected, especially tube amps - the votlage swing can ruin a driver. Best practice is disconenct headphones and turn power off (similarly, turn on and then connect headphones)
Please tell me, are the PSVane EL34-PHs similar sounding to the Gold Lions? I assume those are the KT77s? I have my replacement Nirvana coming Thursday (excited to get going again), and I intend to roll immediately. The KT77s are brighter than my Telefunken RFTs, but I wonder how the PSVanes compare.I was lucky to find a good conditioned Nirvana v2. After it was settled in my system,
I began rolling out both tubes, running a gold lion and PSVane EL34PHs (retro).
The amp is paired with Susvara and Utopia OG, very happy with the results.
