This VX-351 has literally never suffered the indignity of having anything plugged into it, though I did occasionally fiddle with the two attenuator knobs when the unit was close by and I was on a particularly long phone call.
It’s in essentially brand-new condition, and I’ll sell it for $200 to the first lucky caller–um, I mean e-mailer who’d like it. You can reach me at tomhues@hotmail.com or tommyhues@sbcglobal.net.
Thanks for your interest, and may your personal attenuators always remain unfiddled with–unless you request such.
