Hi, someone asked me to build them a guitar/mic preamp with compression and EQ. I have some ideas.... like maybe a simple 12sn7 5687 tube pre with transformer inputs for mic and instrument. The simplest compressor around seems to be the PRR varimu though if anyone knows of something else I'm all ears. I have looked for some type of EQ but can't find anything. I'd like to stick something in between the input stage and the line stage. Does anyone know of something I could make on one board which would fit the bill? I could actually get paid for making this! I wasalsothinking of building one for myself.
It would go into a 1U 8x17 box. If I put tubes and transformers on the back of the box it seems do-able.
Here is a present for anyone who helps ... http://www.fairradio.com
They have some decent prices on tubes... $4.50 for NOS 12sn7 or 12sl7 for instance. Or buy this radio thingy called car-mon-87 http://www.fairradio.com/car-87.htm
For $7 you get a 300-0-300 35 mA power transformer, some AB locking shaft pots, some nice tubes and ceramic sockets with sheilds, a 600:600 AF transformer, bunch a nice resisters and caps etc. I bought 2.
I was almost done with my Telefunken V672 but then I scored this cute round VU meter so I have to take off the panel and put the meter in and make a driver board for it now.
