Hi fonik!

Do you still have any PCBs available? I'd like to order this if you do.

Thanks!

fonik · Posted: Mon Oct 18, 2010 1:44 am Post subject:

the PCBs are in, and i still have spares to sell...

i am in a workshop meeting at my daily work for all the week, so things will be go a little bit slower than you might expect from me. i am sorry for that.
however, i will email or pm everybody who ordered PCBs this week, telling you all needed information about payment...

You know...I've got a couple of the CGS Real Ring Modulator PCBs lying around somewhere. I think I might add a switch to apply the VCAs to either the RRM or to the RM on this PCB...or maybe just split the signals, attenuate them and have dual outputs...or something like that. thinking

so everybody who indicated interest in PCBs should have been contacted by now. check you email/pm.

concerning the documentation. due to the workload in my daily job i have not had time to work on it. i will upload schematics and BOM soon, which should be sufficient for the most of us, i guess. the actual build docs will ahve to wait until end of next week, though...
