So I was tracing down a crackly sound that was intermittent in the pro junior. The chopstick test revealed nothing. Noise disappeared when I removed the phase inverter, but not when I removed any other tube on its own. So, I started shorting things to ground with a test lead. Well things are a little tight in there and I was working around the phase inverter and accidentally shorted a part I wasn't supposed to! Between C11 and R26 on this schematic (yes, that would be right between the power tubes and output transformer HA HA HA! http://www.ampwares.com/ffg/schem/pro_jr_schem.jpg Well, when I switched the amp on, R26 went up in flames and I got a nice little light show. This happened instantly and my hand was still on the switch so I flipped 'er off as fast as I could. The whole thing probably took less than one second from power on to power off. Hopefully that's not long enough to majorly fry anything. I decided that it's time for me to take a BREAK from this thing to get my head straight. Obviously I wasn't thinking clearly when I did THAT little move. Incidentally, the little 1/2 watt resistor, though charred, still reads very close to within 20% of its rated value! I'll replace it and C11 too for good measure (though it looks fine) and hopefully I should be okay. There was a little scorch mark on only the top surface of the circuit board which I cleaned off very carefully and now it looks good as new. Trace side of the board is fine. SO, congratulate me on my first big really stupid mistake, i've been tinkering with amps for a year now and never majorly f***ed up until now, and I didn't even get shocked. I think that's cause for celebration.
