Bill, I'm glad I met the local guardian of the forum. I am so sorry but English is not my native language, so I didn't understand a bit how to delete the duplicated post 🙁. I decided to write in this thread, since a couple of pages above the amplifier I was interested in was discussed. I think it's better to ask a simple question here than to start a new topic, I apologize if it is not accepted here/contradicts the rules. 😥
p.s. yes, for the above reasons, I made myself such a nickname х)
