Anyone have any opinions?

Hi, i'm a student of electronics and i'm thinking about making some audio gear... i thought about moog filters because they look pretty simple to create, here's my question, has anybody made one of those? i mean 901A, 901B, 901C, 902 or 904C? which one sounds best?

Hi all,

I'm in the process of installing a new line mixer at the local grade school and I'm having a ...challenge... figuring out how to connect it to the old existing amp (which still runs perfectly.

I have an old Groove Tubes 6TM mic with the PS1 Vacuum tube power supply. The mic end looks like the Groove Tubes EC7 cable in that it has a 7-pin connector. The power supply end looks like an 9-pin ADAT sync connector almost like a vga computer display connector. I am in need of the pin out configuration so that I can build one or a source to purchase one.

Ive recently been wanting to build my own 212 cabinet, and fill it with some nice speakers that have a really crisp low end clean for recording. Ive researched a bit, and i really cant decide which of these i should roll with.
Does anyone have any opinions?

Hi and thanks for taking the time to read this post.

I have purchased a nice dac which uses an Burr Brown opa2604 opamp.

Can anyone suggest a good upgrade. I was thinking of the ever popular BB opa627ap but have been told this is quite old and should really consider a modern one.
