Need NC-183D (early) schematic
Folks, I just acquired what appears to be an early NC-183D receiver and
got it back on the air via 100% re-cap and a handful of resistors. My tech library copy of the book is (I'm assuming) of the mainstream production model; that is, a 6SN7 for the S-meter and audio phase inverter. This receiver, of course, has the miniature tubes in the IF chain but retains the older NC-183 6J7 phase inverter, etc. No big deal, but I'd like to (at least) have the correct schematic. Thanks for any leads. Happy Holidays to all!!! Jeep/K3HVG |
