I have been trouble shooting for the past couple of weeks and I have finally got this amp up and running.
I had sound coming from it, but it was super low in volume and it sounded like it was distorting the speaker.
It turns out that I had a bad solder connection on the middle of the circuit board. A couple of weeks ago I took the amp to a local amp tech (he offered to look for free) and he pointed out that I had one electrolytic cap in backwards. In amplifiers there are some caps with a positive charge sign + and they need to be connected correctly. Luckily for me, it wasn't a large one that could have exploded.
When I turned that cap around I didn't make a good enough solder connection. With the help and suggestion of Robin at http://tubeampnetwork.ning.com/ he told me to turn the amp over, turn the power on, and take a chop-stick and move the wires around and listen for a bad connection (keep one hand in your pocket or behind your back if/when you do this). That poking around helped me find the bad solder joint.
It sounds great so far. I have not cranked the volume up because - 1. the speaker is new and needs to be broken in and 2. everyone in the house is already in bed.
So far it sounds nice with clean sounds. The boost function makes it brighter in both the up and down position, but a different amount of bright sound so the switch provides 3 distinct sounds. I'll need to get a youtube account shoot some video and posts the sounds.
