    I was using an old Mullard EF86, switched off with a JJ or a Seimens. They all made various noises to some degree - rattles, etc. I put in a shock-mounted tube socket, dampers on the tube, all the usual stuff. I just got tired of fighting it.
    The JJ was good, but after some hours, plop...

    So between the frustration of that and the fact that it was originally built for someone else, I never liked it enough to say, "I'll play this one today." I'm an unashamed Fender guy, so I decided to rebuild it into something <I> want to play. And, even though there are some setbacks, I think I like it better already.

    Hey All,

    I know it's been forever, but I think I finally wrapped this dopey amp up!

    It's now essentially a SF Fender Normal channel & PI/output, with a tweak to the Treble control to give finer control, and an added Matchless/Vox-style Cut control. I finally have a useable tone control system for it, not too tubby & can get as bright as you want but still have pretty fine treble control. I've changed a few resistor values on the power tubes, just for a better safety margin. I'll see if I can draw up a final schemo &take some voltage checks & stick em here later on.

    Thanks for all the ideas, help, & I've learned a decent bit through all this.

    OOOhhhhh. No you di-ent!!!

    Bad form, man! I use to be a pretty good player. I play about as much now in a year as I use to play in week. I can't even remember any of the songs from the ten sets I use to know when I was gigging!!! A friend heard me play about two years ago and said "You sounded like a bad imitation of yourself." Harsh. But I took it as a compliment because it meant I once DID have a groove of my own that was valid and recognizable. Still... Do I want you guys to hear me play now? Not so much.

    Nosaj is cool! I'm not scared, anyway. Just too lazy to learn something new & too broke to buy junk that would make it easier.

    Hah, I can't much play anything more complex that Credence Clearwater. But when I toured with the big horn band, our guitarist had all those mile-a-minute Terry Kath solos down pat. But one day I was tuning a guitar and played a bit of Funk 49, a very basic lick from the James Gang. He comes running up, "Ooh, how do you play that, I can't figure it out." You're kidding, all those Chicago solos?? "Ah, all I got is speed," he said. Go figger. Forty some years ago, and that was the last time someone wanted to hear me play anything.

    Same here, I haven't gigged for over 10 years and haven't picked up a guitar in a month. When I do it sure ain't pretty

    Well, I do know lots of guys who know every lick known to man, but who couldn't walk into a bar jam & improvise to save their life...
    I know we need both types, but I personally prefer to be the latter.

    Normally when people put me on the spot like this I just unleash a flurry of incoherent noise that shows the amp can sound good even if the operator doesn't.

    Another trick is (if I know the customer well enough) to daisy chain all my pedals together & set up an oscillatey squealy mess, & then leave a message of "I got your amp fixed, come pick it up any time" followed by a recording of that mess.

    I know. Symphony guys are used to reading off a sheet, not jamming. Just poking at them.
