    This is a great clarification! I was not aware of this difference in tube amps, only the danger of lower impedance for solid state amps (I've seen a few get fried over the years). I'm well inclined to take your word for it; there must be a reason for having two jacks. Thank you!

    And as far as I know they use exactly the same parts. ( 'cept the speaky)

    I think I've read that they use the same pcb and circuit with a few component changes?

    I think it would be most accurate to say the 68 is assembled in Mexico and the 65 is assembled in Usa, idk where the parts are actually manufactured.

    Same prepopulated PCB's, same cabs, same tubes, same mounting of tubes, different speakers ( probably better) and some very few tweaks that make it sing more. Literally a couple of resistors difference.

    Here are the two chassis

    exactly the same.

    For me it's perfect, because I had a 1968 Twin Reverb, that I had modified in the 1970's to do all the same stuff. I detect NO lack of quality or build compared to the 65.

    Very cool gut shots!

    Are fender PCBs manufactured using a robotic soldering set up? (like the wave soldering etc. I've seen in pedal manufacurers videos?)

    I never meant to infer the 65 was better quality than the 68 by mentioning one was USA and one was MIM. I only intended it as a clarification to a previous post.
