It has never sounded better!... I got to watch the whole bias process, and the amp tech, who was great by the way, said that there was an extreme amount of detail and care put into the building of the amp. He said everything was great quality. He took me through each section and told me what it did in the circuit, really cool.
The dynamics and sustain are so awesome... and the volume is much more usable.

That's what we like to hear Glad the 5u4 is work'n for ya. I thought the Route sounded awesome with it in there. Then again I loved it with a 5ar4 also.

I have been using both in the last year or so, since i got my Ghia I have switched back to the GZ 34 for a bit more headroom. Both are great in this amp.

The 66 has so much sustain, I find myself just hitting a note or chord and just hanging there in amazement. So cool.

when all is said and done incl. bias, does this only affect the output section? not the tone stack? I mean, is the recto only to make DC for the power tubes, and *not* the preamp tubes?
because, sometimes I like to remove the tone stack, and thus remove the aggressiveness, by turning the T & B all the way OFF and max'ing the V for a big soft sound. In theory if I did the all the same things as you would I have a lot more breakup at this setting?
if so, I think I'm kinda happy how it is and I don't want to engage in any mad science ... been doing that for so long. I'm on vacation from all that! Maybe one day, when it's time to freshen tubes anyway after I've gotten my mileage out of what's in there.
still, this is intriguing, seductive info

Hey Mike,
The earlier break up is not as dramatic as i may have made it seem. It just a bit earlier. For me, the thing i like the most about the change is less volume, but in a good way... the thing is still really loud, but whereas i used to have to pack the air brake for rehearsals, i can pretty much go without it... mind you we would be playing really loud... thats if i just want to use the amps break up.
There is definitely more picking dynamics early on.... I would say just buy a 5u4(they cost like 14 bucks) and pop it in... if you like what you hear get it biased... if not, stick with the gz34... the 5u4 is just going to lower the overall plate voltage, so dont have to worry about the tubes getting too much heat or anything.. they will be running colder.
Anyways... either way the 66 is awesome.
oh, and you could totally still lower the treble and bass for that soft clean sound.

I've heard replacing the recto w/ a 5u4 gives the Route a more Tweed like sound. Whatever that sound is it is a good one. For anyone who owns a Route I would recommend trying it at least once.

ya, when the tech was showing me the amp the insides of the amp he pointed to one section and said that it was very much fender tweed in design.

i recently put an rca 5v4 in my kt45 and rebiased, it definitely changed something, hard to describe, a little softer but still seems as loud but not in an aggressive way. less percussive maybe(they describe these amps as "percussive") much smoother. i like it a lot. might not go back. sounds more fendery which i like
