Title: Input measures and looks (signal LED) great, but zero output?
Post by: orangepeeled on February 27, 2021, 11:11:10 PM

Hi everyone,

Just finished up my first of two MP566s today.  The signal seems to work exactly as expected.  However, there is absolutely zero output.  Not even any noises.  Any idea what I should check first?  Is it possible to install the output transformer backwards?  I didn't think the pins were symmetrical, but maybe they are.

Thanks,

Brandon

Went back through and found some suspicious solder joints...  Reflowed them and all is well!  False alarm.  :)
