Does anyone sell an INA217/1510/1512 PCB or have one I could etch?

Hi all,

I am working on some basic preamps for my setup and I'd like to build 8 channels of an INA217 pre to use as my primary preamps.  I'll be adding a Seventh Circle for color a little later.

Does anyone know of anyone who sells PCBs for any of these chips?  Or does anyone have a PCB design they wouldn't mind sharing with me that I could etch?

Thanks!

I am looking for a cheap solution.  :)  I've already got everything I need except a few caps and resistors, so I'm trying to find a PCB to either buy or etch.  :)

Thanks for posting, though!  Looks like great stuff.

Theres a self etch file in the documents for this - just check the scale of the PDF. Its off, and I haven't gotten around to fixing it.

Thank you for sharing this.  I had not realized the PCB was in the PDF.  You are awesome, sir.  :)  I'll do some print outs tonight and see if I can get the scale right.

See if the scale is right on this one and report back.

Its 100% correct when I print this PDF on my own printer.

Sorry it took me so long, but I finally have an answer for you.  It did not print out to the correct scale.  A bit small.

Here's a pic:

I have some spare mic pre-amp pcbs which I got from Australian Technical Production Services many years ago. They use INA217 - if you are interested I could send you one from UK.

The pcbs are still being sold on Australian ebay, the seller is r-jf and the item is called
"PCBs for microphone Pre-amplifier using INA217/SSM2017 - Eight pack"
If you google that, all the info about the project and schematics etc are linked from the ebay listing.

Seriously?! That would be awesome! I think @Gustav 's had switchable phantom power too.
Are you looking for single-sided design that you can etch yourself, or do you want to get some boards? I can do either/both. I'm looking at a turnaround from JLC of only about a week, so I should be able to have a batch made up and ready pretty quick. I would use the stock circuit from THAT, which includes a soft start phantom switching circuit that I've found works pretty well. The Five Fish preamp using the THAT chip also uses that phantom circuit.

I would include output options for either an active balanced out with an additional driver chip, or just a simple passive balanced connection, which should work fine in non-critical setups, especially if the output cable is short.
