    I have a shot at a clean 60s SFDR. The amp looks killer and has very obviously been professionally serviced. At some point, someone replaced every single cap on top of the board with those mustard yellow caps that people seem to like. Filter caps were replaced, too. What impact will replaced tone caps have on the amp's sound? How noticeable is it? Does the impact diminish over time as the new caps are used and worn in? Would you expect the tone cap replacement to affect price?

    And in case it helps, I am not looking for an investment. I am looking for a killer sounding a.m.

    Do yourself a favor and snag that amp. I have a 74 SFDR and love it. And it had been completely recapped when I acquired it and if it made any difference in the tone, I can't say. All I know is it sounds amazing.

    That isn't a thing - caps either work, or they don't.

    I would expect this amp to be priced lower than one that hasn't had that amount of work done, as it's not necessary to replace every part on the board. Whether or not you're looking for a collector/investment piece, the price should reflect that.

    It could still sound fantastic, and if the work was done well it would be a great amp. Do you have pictures of the guts?

    Overkill with the cap replacement, but not a negative. If you can hear a difference, I'll buy you a Coke.

    If any of the original caps had drifted from spec, the amp wouldn't sound/respond as intended by the designers.

    So yeah, the amp would sound different with proper-spec caps in it.

    If all the original caps were okay, then the difference would be negligible. However, the re-cap, if done properly makes the amp a whole lot more reliable because caps (especially older ones) do have a lifespan.

    Thanks to everyone for the clearheaded responses. I'll post some pics when I get it.

    Overkill with cap replacement probably only really matters with tweed-era stuff...less so with brown/blond, etc.
    I'm pretty sure it's meaningless by the time you get to SF.

    I don't think it will be an issue with good caps. Clones sound good without vintage caps. If it's a 60's SF it will have the good BF cabinet too! AND may be BF inside!

    I recapped my AC15 Heritage with Mallory and Nichicon caps; mainly due to white noise issues. I could have just dressed the solder points, but I already had the parts, so I figured why not just re-cap it. Fun project, and it looks pretty darn cool! There was a noticable improvement is bass response, but that's about it. Cured the white-noise issue as well. Here's the thing... Had I never played the amp in its pre-recap state, I would have never known the difference. Buy it!

    All of those blue tone and coupling caps are worth $25-35 apiece. Someone sold them on an auction site. The value of the amp has been decreased IF a prospective buyer understands what is being offered. As a player amp, it is worth less to someone like me with those replacement caps.
    Charlie mentioned tweeds...... The earlier tweed amps that have paper-in-oil tone and coupling caps actually need to have those caps replaced IF one wants the amp to perform as it should because PIO caps do not hold up over time as well as do the later Molded capacitors. There is little reason to hesitate when considering replacing those PIO caps.....if one is going to play the amp and wants to hear what the amp should do.

    You don’t say what year this amp is??? Late ‘60s SF, right?

    Looks like well done work. If it sounds good, do it up. That's really the final judge.

    Other pictures of the amp (bottom of board, back of amp) would be helpful too.

    What makes you say that?

    More pics inbound but I don't have the amp yet.
