Anyone know of anyone selling kits (prefab PCB's, ready to hook) around DRV134/5 balance line drivers?
I googled this up but not in a language I can get... www.diyzone.net
K-Thanks!

Digi01 made some nice PCBs awhile back. See Thread

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...

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?

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?
