Glad you made it work again.

I have a question: how loud (acoustically) the scope is?

Thanks!

Kirkhaan:
I don’t have a SPL meter here. So an accurate answer I cannot provide.

At start-up the fan’s go to full speed for a couple of seconds.
That sounds really like it is lifting up...  8)
But after that they slow down and are (at least for me) not disturbing at all.

Thanks a lot,  exact dB not needed, just user experience.
Best regards,
Sinisa

Kirkhaan:
I noticed quite some accumulated dust inside, obstructing good air flow through the heatsinks.
I guess this is one of the main reasons for the “overheating” of these scopes that you sometimes reed about.

darkstar49:
It’s more than just dust... the fans are underdimensioned...
In a normally warm room,it will be mostly Ok, but if you have higher temps and/or bad ventilation, think of replacing them !
