Hello I have bought a kit from pcb grinder the ms76 kit.
Have to say was a damn blast building it, will be my first big build over my diyre stuff which is excellently described of the build process.

so my question..

Hi all,

Not sure if anyone can help. Got my 02R96 V2 out of it's box today after not using it for some time. It was working fine the last time I used it, but today it's acting kinda strange.

Screen comes on when powered up and it looks like it's running through it's boot routine. Screen is glitchy, plus when the loading bar reaches the end I get the following message:

So ive had this issue with my subbwoofer that its randomly stops sending out any sound.

it can be dead for a day or two and then suddenly just starts working again.

This video shows the process of changing tubes and comparing the before and after sound. I've did the mistake of recording with low gain to get the cleanest sound possible, before and after.. but it seems the sound is very similar but gets different with higher gain settings.. Anyway I hope it will be of interest to you nonetheless !

Let me know what you think !

hello guys,

So many ways to compress audio. I am wondering what people find themselves using the most? Slow optical, fast solid state, diode, VCA? Which do you find the most useful flavour ?

its been awhile nice to see some familiar faces! Anyway Hello everybody.

Hello,
