Larry,
I had a similar experience with my vintage H/K tuner. I sent it to a modder who replaced the older RCA inputs with current ones spaced apart to fit the larger barreled interconnects. You can probably DIY this yourself fairly easily and cheaply, especially if the interconnects are worth doing it for. Please keep us posted on the Ultraclear progress in your system.
