18 watt post 13

I got rid of the noise. Took me a couple days of poking around, but I got it. I reflowed the solder on the board. Didn't fix it. I reflowed the input jacks and that didn't fix it. I went and got a chopstick and started poking...found it. The wire going from the input jack to the first preamp tube for the high gain channel was not soldered well...it went zzzzz when i pushed on it. I unsoldered and resoldered the wire and now it sounds ever better than before, more gain and better highs.
Now, back to chopsticking. Why use a chopstick or other similar object? Electricity kills. The voltages in the amp I have been building are over 300v dc...more than enough to kill you. Don't think about using a pencil either...graphite in pencil lead is a conductor of electricity. Chopsticks, wooden dowels, a plasitc rod...anything that won't conduct will work.
Have karate tonight. When I get back I plan to record the amp and post the clip and some new photos.
