    Start at the very beginning. Try a different power cord. If the pilot light doesn't come on there's probably no voltage getting to the transformer in the first place. Check where the A.C cord comes in. Test the fuse because many times they'll blow inside the chrome end where you can't see it. If by "nothing" you really mean "NOTHING" that's probably it. Anything charred or burnt?

    Why bother? A decent technician can fix that amp in an hour, Assuming it doesn’t need a new power transformer. Even then, that’s not difficult to put in but usually you have to order one. Independent fender service centers do tube units all the time. The real problem comes in with intermittent issues. If the amp is dead or constantly malfunctioning, it’s easier to diagnose.

    Fix it yourself and double the gratification, or enlist a crafty tech, help him pay his light bill, and still be gratified. Win-win.

    So I'm catching wind that I might need a new PT.

    Again, I'm looking for more info to weight all my options. I love the amp, it's been a rock all these years. Depends on the tech cost, and I'm willing to a little more work.

    Never throw out an amp. Donate it to a friend.
    Sincerely,
    your friend, Bill

    If you are really going to throw it in the trash, I'll take it. I have a good tech guy. :)

    I'm a Mesa Boogie guy. Not sure what you budget is, but Randall Smith got started by modding Fenders.

    Mine crapped out. Took to the local amp guru and it turned out to be a bad solder connection. $45 as good as new.

    I understand completely. Much luck in the repairs! I would be curious of what that right price would be though. Feel free to pm me

    I really doubt that you need a new PT
    The fuse has probably done its job and protected it. You can check by finding the input side of the fuse and looking for 6.3v AC
    Fix the fuse holder and obviously damaged caps and then go looking for a short downstream in the heater circuit. The candidates would be faulty wiring or the tube sockets, the pilot lamp or holder or a shorted tube

    I'd say your blown cap shorted internally and took the fuse out. Some tubes lit and others not, indicates maybe a bad solder connection at a tube socket. I don't know whether that board carries the heater traces but I presume not.

    That fuse is apparently on the heater circuit only, no capacitors fed by it

    LOVE my TMDR. Can set the attenuator to .5 or .2 watts and get a great over driven sound late at night in my house without waking up a soul.

    The Firmware update has made it even greater. Took out the Bright Cap setting, and the Reverb is perfect now, even at low volume.

    What makes you think the PT is shot?

    Another member mentioned by DM that the fuse was in the B+ high voltage line and therefore something major shorted out, possibly the PT.

    I suppose I'll post some better pictures, but I'm heading out to Tejas for the next 5 days, no time for amp work right now.

    I once had a guitar player who experienced a similar issue. After wasting all kinds of time and frustration, he finally came to me. My first question: Is the amp plugged into the wall? Lo and behold, it was not.'

    Get rid of it. Put an ad on Craigslist offering it free to the first caller. Someone more clever than you will figure out how to fix it and have years of trouble-free playing. You will have a new Tone Master. Everyone wins.
