Sure.
On the VO I prefer the GZ32+Tung Sol 6SN7GT Black glass/round plate+RCA 6080 or GEC 6AS7G or Tung Sol 5998- *this is a super warm roll,but has very deep holographic imaging.
For the VC I like the GEC U52+ Ken RAD VT231 staggered plates(apparently the KR 6SN7 sounds the same) 6pack of 6BX7s (im using GE as thats all I have).
At RMAF I believe Zach was using GZ34+ Tung Sol 6SN7GT black glass round plate+ Tung Sol 5998 for the VC,but dont quote me on that.
Rectifiers=GZ32,GZ34,GEC U52
Drivers=Tung Sol 6SN7GT BGRP, Ken RAD VT231 or Ken RAD 6SN7
Power tubes= Tung Sol 5998,GEC 6AS7,RCA 6080,6BX7s
GZ32 is fairly easy to find and not stupid expensive. GZ34 is harder to find and usually goes for over $100.00. GEC U52 is God Tier and can go for over $350.00 and up.
TS 6SN7 BGRP is generally considered to be amongst the very best of this type of tube,and not cheap. Ken Rad VT231 is not as expensive and is known for ethereal sounding mids and fantastic bass.
Tung Sol 5998s are about 200-400.00 for pair. Brighter sounding with good extension and wide staging. GEC 6AS7G is God Tier and quite hard to find. Expect to pay over $500.00 for a pair.
6BX7s are easy to find and can be found for as little as $12.00 each. I use 6 at once,but you can get away with 4 or even two(i think). Fast and snappy with great impact.
RCA 6080s are dirt cheap,and easy to find. Big bass. Warm and romantic.
Im sure
@UntilThen and
