I would think the sticker should read "KT-88 to EL-156", not the other way around. I've seen this same thing with adapters meant to convert 7199 amps to 6GH8 input tubes.
To paraphrase Deep Throat in the Watergate investigation, "Follow the electron flow".
Semantic rant over. Carry on.

You are using an EL156 tube but the socket converts it to a KT88 base so I would the EL156 to KT88 is the right.
Honest amplification is better than excessive 2nd order distortion anytime.
using wire, resistors, etc. so the amp could use EL156 tubes, I'd be modifying the circuit of the amp. My perspective is that's what the adapter does. It changes the amp's circuit, except it does it temporarily, which is a good thing.
You're seeing it as modifying the tube. Which I suppose is just as correct.
Like I said, it's semantics. At the price of those EL-156, I'm never going to need one of those adapters, not for my MKIII's!
I have used these in a Jadis JA80 using Telefunken EL156 tubes.Once the bias resistors were adjusted the amp was somewhat improved over the KT88 tubes,expensive though.
If the ad in the previous thread is the standard/these days. EL 156s are Expensive indeed!!
