Hi all,
I've been having a bit of trouble with an AML EZ1073 500 series pre that I've built. It largely seems to be working - the relay clicks on and it amplifies sound all good, however the sound is rather thin and tinny, any bass is gone and it's slightly crunchy and quiet. I've gone back through the instructions and checked over everything, reflowed solder joints and made sure my transformers are in the right way round etc but I'm at a bit of a loss as to what might be causing this - does anyone have any ideas what might be the source of the issue? I've built a few pedals before but this is my first preamp build.
The other issue with it is that the phase switch makes the signal significantly quieter when it is in regular phase as opposed to opposite phase.
Cheers,
Joe
