Greetings all, I'm looking for a couple of things: 1. Adapter that accepts tip jacks from old style headphones and converts to standard 1/4 inch plug 2. Knob - same as used for main tuning and bandspread on Hallicrafters SX-24, SX-25, S-19, S-20, and others I'm sure. Anybody have these to sell or trade? 73 de Dave, W4QCU, Oak Ridge, TN
