You can use the CV-378 (GZ-37) but I am not sure about the 274...........

can you guys briefly comment on how each of these rectifier tubes sound in the transporter?

I've only tried two so far a Zenith 5u4gb and Sylvania VT-244. 

I found the zenith to have very good soundstaging depth and space and image "pop"  but a little congested in the midrange and not too linear.  I found the VT-244 to be more linear throughout the frequency range and a little more articulate, overall the sound is very solid and crisp, but it doesn't have the soundstage depth of the zenith. 

I'm using shuguang treasure's for the 6sn7's btw
