Email received. Trying to determine if these Panlocs will fit your amp and I ran across this document on Panlocs:
http://mcc.berners.ch/other/PANLOC.pdf
It looks like there are quite a variety of these, which I didn't know about before.
My Panlocs came on a C26 preamp as I recall, so now I don't think they are the right ones for your amp. Sorry.
Any Forum Mac experts who can weigh in on Panloc compatibility? One thing about Berners document is that it is non-comprehensive, so maybe there is more compatibility than the document suggests.
