    Hi Myles,

    Thanks again for you help getting the SAG-12AX7-M MPI for my Fender Hot Rod Deluxe. I now have the GT 12AX7-M in V1 and V2, and the MPI in V3. The amp sounds great - warm, fuzzy, articulate, and the More Drive channel is actually useful now, although I mostly use pedals for OD and distortion.

    Never one to be satisfied, I am now wondering about the optimal bias setting for my power tubes. I put a set of GT 6L6C's with a hardness rating of 4 in to replace the original issue GT 6L6B red label. I lost a little clean headroom, which is OK.

    Is there a 'best' bias setting for these tubes to have them performing at their optimum, and if so, what is it? I have a digital multimeter, so I can use that and the bias test point. I think Fender factory recommend is 60ma at the bias test point, while some say 68 or higher is best. I don't really want to chance burning up my tubes by constantly changing the bias setting.

    Can you advise me on this? Thanks

    Myles,

    I went ahead and ordered a SAG-12AX7-MPI from the GT web site, to be used as the phase inverter (V3) in my Fender Hot Rod Deluxe. Will I need to rebias my power tubes when the MPI goes in????

    Thanks Again!

    Myles -

    Just to follow up, our friends at Guitar Center did not have any of the SAG/MPI tubes. I ended up getting a GT-12AX7C. I was surprised by the Silver Series designation and the grey silk screening on the tube. I was expecting Red paint like all my other GT's and Gold Series packaging. I hope it ends up being a good tube. On the plus side, it was only $8.99.

    Thanks again!

    Hello Myles,

    I use a Fender Hot Rod Deluxe amp. I recently bought a GT 12AX7M preamp tube and tried it out in each position (V1, V2, V3). I liked the different tones I got when it was in V1 and V2, so I bought another one! Now my amp has the GT 12AX7 M in V1 and V2, and an EH 12AX7 in V3. Sounds really good with my Vintage Noiseless loaded Strat. I'm curious about the V3 tube now. Can you advise me on a good tube choice for V3 (I think it is the phase inverter?) for best amp performance and tone? I'm not opposed to buying and trying several different tubes, but I don't know where to start.

    Thanks!
