    Hi Folks,

    So I built my first amp. And when it worked the first time I plugged it in I was psyched. But, when I put a new battery in it gets HOT.

    Now I have never used a multi-meter before, but when I put a new battery in it is at ore above 9 v, then when I use it for a bit the voltage drops to around to the 7s.

    Then the battery doesn't get hot any more.

    So, erm. I guess I did something wrong. And how do I figure out what went wrong?

    I feel like I have made a lot of progress in the last week, but I am still so new as to be dangerous.

    Thoughts, next steps? Better place to ask my questions?


    edited to add. Just measure the new battery I used. I played for a few minutes and the multi-meter reads 8.1. Is that a big drop for only playing for 15 or 20 minutes?
