How much a difference do the silke transformers make vs the stock transformers?

Not that much difference to be honest. The stock transformers are Eric’s specifications and he got his suppliers to do as he specifies.

The right valve is not pushed in as far as the left one?

But it's not just the looks. Susvara with Destiny takes you back to Brother In Arms. You're in a battlefield, walking amongst the dead, with explosions going around you. You pray that you will walk out of it alive, by grabbing onto the red hot 300b tubes. There in the distance you see the extraction helicopter but just before you reach it, you step on a mine. :wink:

and they award you with a Purple Heart. :)

Tell us more about the KT77? How they compare to NOS EL34?

You can't compare current production KT77 with NOS EL34. Clarity and details are not up to the level of NOS EL34.

The Genalex Gold Lion KT77 do have a non offensive sound. Warm and relax. Reminds me of the Gold Lion 300b tubes.

I had East German RFT EL34 before and they are quite nice but price have also gone up for them. https://www.thetubestore.com/rft-siemens-el34-6ca7
