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 !

What is your PCB revision number?

[igor.moreno]

It's a REV 1.2.

Do you know this modification?

[igor.moreno]

No, I did not know this modification.
I'll try it as soon as I have time.

Thanks !

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.

[igor.moreno]

OK, thanks, i'll try that !

Hi All
I have an LA502 installed into an Bento 10S and it is hissing a lot.
When I go beyond Gain 30 it is a lot of hiss??
When I install it into an Bento 6 I can go up to over Gain 70 before there is a sligth hiss.

Has anybody similar experience?
I have an MP AB528 in series before the LA502
But the MicPre is very silent.

Regards

Some Bento's have a very noisy PSU.
Try moving the LA502 to a slot that is further away from the PSU?
