here is an image off google, the top left box for coaxial input -
IDing copper/brass/aluminum heatsinks is no problem..im just uncertain whether i should put the magnetic heatsinks in steel shred or magnetic stainless. Im talking about the tall flat ones like in the picture and also the shielding that sometimes covers flatpacks or like i mentioned in OP the coaxial input box.
dont know if u noticed but i was MIA from this forum for a long time...stopped picking up ewaste...and i ended up tossing out some of the stuff i collected awhile back...i think im only gonna take the crystal oscillators from now on...very easy to ID. but kept all the boards..i still never took the lowgrade to that yard you were telling me about near 95th
