DRV134/5 kits anywhere?

Given a PCB layout, it'd make a great group buy...

I've used the DRV134 to drive an input transformer at the other end of the cable. The results are EXCELLENT.

We need a PCB layout thats cheap to fab. I'd recommend sockets
for two DRV134s so a single board can do two stereo channels. I'd
also remove the "option" for 300 ohm resistors and follow the mfg recommendations for an "optional" 10uF tant between signal drive and signal sense.

Further, no regulator onboard is necessary. Leave the regulator
parts choice to the end user who likely is going to have either a
cheapo 7815/7915 scheme, or, a properly implemented LM317/337
scheme or an over-the-top buried zener reference with low noise op-amp servo scheme...

Like this? You can strip off the on-board XLRs if you want to. Board measures 2.3"x1.55".

Jim: Coming from a Tin ear'd person like myself... are we sure we want to use tants? Would the signal pass through these tants to any audible degree?

Heh, I can send you the Eagle files but you'll have to do the rest yourself (including testing if it actually works) [😀]

Thanks!!

OK, Once we find a resource to take this on, (Mark G is busy with the Krell threads 🙂 ) we will get the files from you.

Do you have a schematic of the layout with parts etc?
