Hey guys, I am hoping to get some advice here, as I don't want to mess anything up beyond repair. Although I am still fairly new I do have some history in electronics. I've built several effects pedals and a few guitar amps.
This project went fairly smooth until I powered it up (of course), and tried to do the calibration steps. The meter lit up, but was stuck at -1 on both the +4 and +8 settings. No matter how much signal I threw at it, it did nothing. Non of the trim pots or input level do anything. The only time the meter changes is when it has been powered down for awhile or I press the gr button. When I select gr, the meter goes all the way to the right. Eventually the fuse blew. I didn't even get a chance to check voltages, which I wish I did first. I have my power transformer wired for 115v blue tied to violet and brown to grey. I have the center taps, orange and black, tied together and wired straight to the board via the on board terminal. I have the lamp for the meter wired to thie same spot. Does this all sound correct?
Sorry I lack in terminology, I am still learning. If anyone is willing to help, I'd really appreciate it. I can take pictures if necessary.
Thanks
Chad
