    The head includes a Studio Slips cover. It is in perfect working order with ZERO issues.

    I am looking for $1900 + shipping. I have the factory box and will pack the amp in that and then have it boxed and shipped.

    Is that what the mod actually is? If so, someone should buy it. I already have a 70's svt though.

    He modified the preamp section to mirror HIS preamp and then worked on the power amp section, adding additional capacitance
    to the power supply. IF my memory is working today. It's all in the thread I linked in the first post.

    Do have a circuit diagram that details the changes made? That would be useful for a new owner in the event a service situation occurs.

    No diagram would be required to service, so hopefully whoever ends up with this great head will respect my IP. The preamp isn't identical to mine by any means, but it captures a lot of the same vibe and is much improved over stock IMO/IME. I find the stock preamp to distort too quickly and in an unpleasant way. With the tweaks, there is more headroom, overall clarity and low end cohesion are improved, and the overdrive character is sweeter. The power section also has more punch and clarity at high volumes, no mush.
