    Nice of him to acknowledge tubes4hifi as an option for a new kit.

    A couple things I disagreed with-- he didn't appear to realize the board in Roy's kit is modern and an upgrade to the original.

    He believes the original trannies are better than the new-- correct me if wrong, I thought the new ones are beefed up.

    He didn't consider bead blasting the old chassis, chrome or painting them, and re stuffing them with Roy's driver board and other sundry parts from Roy and / or Kevin at Dynakits.

    This would have also avoided the need for a matched quad of tubes, sparing the ones he already has.

    So,I think he had room for a few more proposal options that would have made this a better "resto-mod" project.

    I agree, TN. What was good about this effort was the step-by-step delineation of the costs and the orderly approach. On specifics, not so good.
    The same is true of all of this guy's vids.

    Good point Kentley, I agree. The way he broke down the project proposals on a spreadheet was excellent.

    I'm gonna steal that off him when I lay out my plans for how I might mod my SP14 with exotic resistors, capacitors and tubes.

    I'm still waiting for him to discover that the Audio Research ARC SP-3-A1 he's also working on puts both channels in each tube.  He seems to think that the RIAA section is one channel, and the line amp is the other.  Shocked

    in the end, it seems to me it came across as a sales pitch for him to upgrade your MK3s for $1250 rather than buying a new pair for $1800.
    So you spend $500-600 on some old beaters, then $1250 for a rebuild. Comes out about the same price . . .

    Not really a cost effective way to go.

    If one knows enough to DIY the restoration, and make better choicesfor example, that will allow retaining those tubes, it could be a worthwhile project--provided one wants the challenge of restoring those.
