    You guys are far too kind. Thank you very much for listening and the feedback.


    I did a little experimenting with the circuit but stuck to my traditional circuit for the owner.

    Trying to get everything out of all an analog tube circuit that I can.

    Now thats what I call a nice demo !......thank you David for showing that the amp
    can do Classic Rock crunch !
    What I really like about your amp mods is that they sound fat and greasy while keeping
    their kerrang or grind ,........nice quality to them !
    Also have a feeling this amp can do it all and do it good !...............Nice one David !! :cheers:

    Man, you could dunk that head in a vat of milk and it would still stay crunchy!
    As always, great work and thanks for sharing. All the best to you sir.

    Thank you Terry. There was of course some PI DC experimentation going on. I believe I will work with my personal Pandora and see just how low I can go on one side while keeping DC where it belongs.

    The 82k & 100k is just an estimated offset balance on the PI dual triode so in the spirit of my past practices of using two different complete duet sets of output tubes to make a quartet that burn and measure the same in order to mix characteristics.

    Being an audiophile I can afford to do this in a boutique manner but finding such sets for the general public would be quite costly & time consuming.

    That brown ostrich skin 6G3 you built is a PURE BEAUTY!

    I play her every night with my favorite Stratocaster. It compels and inspires. Sounds damn great over a UK Vintage 30 4X12 Marshall 1960A/B cab as well as the cream backs etc...

    You can’t hide beauty.

    Thank you my friend, David

    You are very welcome as it was a pleasure working on this 1959. This is one of those amps when finished I thought to myself how I would love to keep it. It plays & feels great to me.

    Great sounding amp, The VH riffs sounded awesome. This one sounded even better (if possible) than some of the others. 100 watts of pure bliss.

    Thank you very much Travis398. I have learned what type of components to use in certain assemblies over time to get where I wish to be. But the one variable we just do not know about when modding a amp to high gain is how the output transformer is going to perform.

    Nothing leaves my bench until it is something I would be happy to play live. Just some have the perfect wound iron much like pickups can affect a guitar. We would think it is down to a science and it is but only to a point.

    Thank you El Gringo for taking time to watch and post. I appreciate the great words.

    David
