Gotta add the GT 12AX7M to the list now and also the GT EL34L tubes are great.

JJ E34L's in my JTM60. Love em'.

JJ and EH 12AX7's in the pre.

If the 30 is like the 60, it needs to be biased. The bias post is a bit hard to find, you have to be looking at the chassis from the side to see the blue bias pot.
