[Elecraft] OT: obsolete IC source

[Andy Bullington]

 I'm at my wits end. I'm trying to homebrew a box that will bring all the
audio in my station together in one switchable unit. Its going to have an
audio amp and front facing speaker for the K2 and something called "the
continuously variable audio filter" from last years Handbook for the older
receivers in my shack. I've wanted to build this filter for a long time but
come to find out the Maxim MAX295 chip which is the heart of the filter is
no longer available from the usual sources. Any ideas? Thanks.
