Re: Ferguson 382U Firefly not playing ball
Okay.. traced the distortion to the AF stage surprisingly - as my sig gen had previously sounded quite clean ( although that could have been a few components back now! ).
Using an MP3 speaker I can get nice clean audio on the grid of the UL84, whereas using an iPod as an audio input, I'm not getting much at all and very distorted.
I'm wondering if I've got some duff components around the output stage?
