Thank you!!!
Yes, i use matched NPN's instead NPN array. In A-B listening test (mic->splitter->two channels->ADC) i dont hear big or small difference with MAT02 and SSM2210 (both discontinued).
Add protective diodes and forget about it. More changes you can hear with LME49860 or AD823.
Hand soldered

A-B test with RED1 (snare)

Great concept!!
If I may ask, which NPN's did you use for you array's?

Many thanks

Hello! I like 2SC2240BL. Very transparent and noiseless.
Diodes 1N4148 emitter ->| base

Oh man these look amazing...

Is smd stuff hard to solder? I've never tried. Watching some tutorials on it right now...

How many of these fit in a 1u? what's it cost per channel roughly to complete?


Thanks!

I just did some SMD work for the first time recently. As long as you aren't using the super tiny parts that require anything more than a little magnification...it's cake. There are a few things that seem counter intuitive as compared to through hole soldering. Like the idea of intentionally creating a solder bridge to solder in ICs then cleaning up the bridges with solderwick. I did 8-pin DIP ICs just dragging a heavily tinned iron tip across the pins. Amazing!

Are PCBs still available?

Also, the link: http://www.multiupload.com/PQAHKGL4P1 doesn't seem to be active. Is it just me?
