By the way, the stock tubes are all JJ now. No more Tung-Sol and Electro-Harmonix.

Happy to. My Telefunken smooth plate 12au7 sounded more punchy and resolute as well as more extended than the GL input tube. I talked extensively with Brent Jessee about the KT77 as a drop in replacement for the EL34s. He said electrically it’s so close that it’s perfectly acceptable and fine...

Oh wait. See your Gold Lion is input tube. Sorry. I’ve got one of those and not impressed by it.

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...

So while awaiting my replacement Nirvana I’ve consulted with an amp and EQ builder I know who is highly respected in the pro audio world. I’m actually having him build me an EQ. He said you absolutely CAN put an XLR balanced EQ ahead of the Nirvana AND use it in a boost situation and it won’t...

The answer is no. I have discovered a not insignificant channel imbalance. Suspected all along. Really had to dig in to confirm. Perhaps is why two input tubes died. I’ve attached below what I just sent Moon Audio. I have confirmed with different headphones and cables using several quality...

Sadly, the second of the ecc82 Telefunken pair is dead. The left channel was staticy and I verified this to be from that tube. Is the equalizer too hot and overdriving the inputs and causing this?

I know I’m posting a lot. I’m sorry. Am just wanting to be helpful and not only just asking questions. Went back to said Peter Gabriel I/O album. Same Telefunken smooth plate 12au7. Rolled power tubes to the GL KT77’s. Mentioned last night I am on this combo now. Coming from Telefunken power...

So the Genalex new production Gold Lion KT77s are burning in nicely and sound superb with the Telefunken smooth plate ECC82. They are just as detailed and punchy as my Telefunken power tubes but are a touch brighter. In a totally tube like smooth, good way though. Best sound yet out of this amp...

Thank you. I hope my HEKse ok. They SOUND ok. Guess it would be obvious if damaged.

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?!

Oh, and I don’t like the new Russia production GL ECC82. Not nearly as good as my KT77s from them.
