Distortion mostly in one channel
Oh no, do you mean permanent distortion? Convert output too hot?
I've found most amps can't hande the full output from Convert 2. Use the trim pot or a transformer to reduce the voltage.
I thought introducing a balanced preamp would help. But seems not (unless the preamp has a problem)
Yeah, convert output is a bit too hot. It does a great job with the Jensen Iso-max though
