Hissing LA502
Hi !
I've got LA502 I built years ago that I don't often use because of it's hiss, which can be too much depending on the sources.
Is there any way to atenuate the hiss ?
Thanks !

Re: Hissing LA502
Hi,
One of the knobs screw broke, making the disassembly of the unit impossible...
Do you have any tip to remove the broken screw on the knob without making too much damage ?
Thanks,
Igor

A 2.5mm drill into the hole. If the thread is damaged, it does not matter because there is another screw on these knobs.
