" Icon also is a new name to me. Class A, pentode/triode, 28/20wpc, enabling SE drive using KT150,,, and with open chassis! I understood this specifically designed with KT150 and not that one can play with tube exchange but this is interesting! I may need to do a deeper learning on this Icon. "
Yes this amp was originally built by the owner of Icon as an end game amp.I've run pretty much every power tube available,in every Class configuration they come in & was confidant that Pure Class A,Single Ended Pentode is perfect for my musical tastes & speakers(Harbeth M30.1)...It's so sweet to be running Ultralinear for hard driving classic rock/Chicago Blues & then switch to Triode Mode for Classical/New Age/Jazz..I'm past the desire to tube roll as well so another reason I went with this amp,EVERY aspect is completely optimized for the KT150..
