I'd be VERY leery of trying such an operation.  Old equipment like the
Echotron is generally a one-off affair, and not meant to be upgraded.
Unless you have some explicit reason for wanting to upgrade the
Echotron (like its user interface, or superior sound quality), I'd say
spend your money on a JamMan or some other long delay instead.  Toying
with the innards of the Echotron may well destroy it, since it
probably has a number of static-sensitive MOSFET digital circuits.

Nope, they went out of business many years ago.  Your Echotron is a
genuine vintage device now.  Enjoy it... I have one myself, and I
prefer its sound over supposedly higher-fidelity modern devices. 


By "beauty," I mean that which seems complete.
Obversely, that the incomplete, or the mutilated, is the ugly.
