My Route 66 has the ghost notes problem. I installed an Amperex ef86, a good 12ax7 and an Amperex GZ34, which helped quite a bit, but the undertones are still there. (The power tubes are new Chinese KT66s, which I like better than the Russian tubes.)
Dr. Z told me I could experiment with bias settings, and I have, but the ghost notes are still there. He also said I could replace the 50/50 multican with a 100/100, a drop-in replacement, but that it would change the feel or tone of the amp "to a slight degree."
What do you guys think? Would any of you try it?

Jazzwannabe, Sorry to hijack your question here............but I was wondering what ghost notes are? I have read many reviews and posts regarding the RT 66 and ghost notes........does it sound like 2 guitars at once? Does it happen at all volumes? I know when I crank the Rt 66's volume up to 5 oclock....with the treble "dimed"....it sounds so thick that I often feel like the single note stuff is two guitar tones........one playing the notes and the other playing screaming harmonic overtones...all woven nicely into one tone....................can anyone enlighten me here? ?

I got my 6545 used and I found those ghosts in there (shame on me, I know). For me it was like playing with a ring modulator at certain frequencies. It was completely aggravating. Retube/rebias didn't recover, a trip to the Dr. did. I can't say I know what he did, but I'm recalling that the caps were replaced. I also remember that he did mention that he replaced some resistors with some values he liked better....the amp just sings now! jazzwannabe (I can relate!), I'd say "go for it" as you can always go back.
19jmm68, if you like what you're hearing, you're golden. In my experience the sound was completely unusable and certainly unmusical (and I *like* ring modulators!). I'd venture to guess that what you're hearing is what we all love hearing in our Zs....our guitars, ourselves.
