I have the pre amp assembled excluding the 3 pots. So far my only complaint is the mounting holes are stupid small. This weekend I'll get some type of power supply (even if I have to use my regulated bench supply) and give it a listen.

Need to find a housing.

I ordered this pre amp kit and it arrived today.

Stereo Tone Control 3 Way Audio Preamplifier Kit Bass Mid Treble Analog | eBay.

the documentation is here www.siliconwiz.com/k330/doc.pdf

Really small 2 1/2" by 3 3/4". Almost too small for my plans.

I ordered this because to me it looked like a decent pre amp.
It uses LME49720 which seem to be great chips, seems to have above average capacitors.
I like the tone controls where they are (60hz 1k and 8 k), and it came from New York.

I may need to order a power transformer since this thing only requires 65ma and they recommend a 17 volt which would be hard to find so I'll probably look for a 15-0-15 supply.

Suggestions greatly appreciated, I'm a noob who prefers to just assemble kits and leave the designing to those who enjoy all of that math.

Thanks

Where is PCB lay out? Please share PCB Layout

I typically use something like a block 6VA 12-0-12 trafo, 7815/7915 with 470-1000uF both sides of each regulator, (even though i likely dont need more than a couple of uF on the output.

Apologies....thought i had read the last page.
