I feel compelled to post this every so often: When you're asking technical questions about your amp post detailed pictures of the insides. They need to be detailed and crisp enough we can read values and codes on the parts. That provides us with the information we need. We can tell what the amp is and get a general idea of its condition at a glance. A few of us may be able to spot problems. Otherwise be prepared for WAGs (Wild Ass Guesses) which may or may not be helpful, informative or correct. The "D" in TDPRI stands for "discussion". That means you need to do your part to participate. Bear in mind that it's challenging for technicians to communicate with a non- technical audience. It may be frustrating for you to understand a problem that's outside of your skill set. It's frustrating for us to try to communicate with someone who doesn't understand what we're saying. The technicians who post here myself included post free detailed information that may save you an expensive trip to your local tech. Knowledge can be money, baby! We can save you some dough on repairs and parts. You might not need to buy tubes over and over. You might not need to buy half a dozen speakers to find the right one. You might not need to buy expensive parts if a nickel and dime part does the trick. You can be part of the problem or part of the solution. When we say, "Take it to a tech!" that means we've considered your situation and you're about to make a small problem bigger. You may damage your amp or you may damage yourself.
