Looking for Audio Connector for A/N GRR-5
 

Does anybody have a clue where I can buy or get a headphone connector,
Amphenol 164-7, or headphone cable assembly CX-1334/U for an "angry five"
receiver? I've tried the usual suspects; Fair Radio, Nebraska Surplus, etc.
with no luck. Is there a suitable substitute that can be used or modified to
work with this set? I've owned & used this receiver for over 30-years & it's
still going strong.
