They were a big improvement compared to the Tungsol's I got from Nik, but then again I don't think those Tungsols were a 100 % ok. I just built my second Ceria overtone for a friend, and this amp was equipped with JJ 6L6, and we did a quick comparison, and we both agreed that the TAD's opened the amp up a little more, and there was a more defined bass response..

Both amps were equipped with NOS ECC83 (mullard tubes), and the V1 and V2 preamp tubes makes a big difference in sound compared to the powertubes... So I would start with the preamp tubes

Thanks for the feedback. I burned out 2 sets of the TADs in my Super Reverb over the course of about year. But they sounded great in that amp. I am going to get some for the OTS.

I agree about the effect of the pre-amp tubes when going from really bad tubes to good quality tubes. I have about 30 spare pre-amp tubes, and about a dozen NOS tubes, including Mullards. But I still find myself going back to the JJ ECC83S all the time.
