Is a GZ34 the same as a 5AR4 sort of like preamp tubes how a 12AX7 is the same as a ECC83S? If it matters, I'll be using two 6L6's.
yea, they are basically the same. they have a different sag to them (as rectifiers go), but one can replace the other.
for what it is worth, i like the GZ34 from Eurotubes. seems to be more reliable than the Sovtek 5AR4 that came stock in my AC30CC. i replaced two Sovteks in a 6 month period, and the GZ34 has been a keeper for a year.
there are some sound differences, but i can't really tell too much.
I have had Sovteks go bad on me too... with the JJ's, I have had no problems... but there are some out there that swear by the Sovteks.
I am always really confused on the whole current production rectifier tube thing...
but what choices do we really have? jj's, chinese or sovtek...
Used Mullards are a good buy even though they seem high priced, but after you've replaced several new production tubes you could have bought that old Mullard and it will probably last your lifetime.
