Does anyone know where I can find a manual or schematic for this kind of gear? I have not found any 'tribute' sites and the company seems to have disappeared into the ages.
I have a TX-4A solid state television modulator, nice rackmount unit xtal ctrl'd on channel 3 and another one on 13. Says DYNA-MOD on the front. Opening the cover exposes very easily worked-on circuit boards.
I've had several Dyn-Air equipments over the years, always nice stuff.
Also have a Jerrold Uni-Mod UM-8 (ch
modulator, also rackmount.
