National radio
I need a diagram for a National NC 77X. Could someone email me one at jandpgraber@connect2.com?
Thanks, John |

Doesn't look like BAMA's got it, but maybe there's something close enough to add some value?

Sez here it was made from 1963-67, looks to be basically an "AA5" that picks up the SW bands, too...Tubage is 12BE6 converter, 12BA6 IF amp,12AV6 detector amp, 50C5 audio output, & 35W4 rectifier. Sposed to be kinds rare, so even tho its a "modest" set, it'd be worth fixin' up...This was pretty close to the end of the line for National, they were gone in another few years.

Sorry, but what's an "AA5"? Not familiar with that.
Thanks, JG |

"All-American Five". There were literally millions of radios made that used that basic design from the end of the war til the end of the tube era in the late '60s.

5 tubes, series filaments (no power transformer). Funny thing is that there were plenty of AA5 radios, and tubes for them, made in Japan :-)

Unless something's really awry, getting that National up & running should be quite straightforward. Simple circuitry means you won't have to spend a fortune on a recap, tubes are cheap & readily available should you need to replace any. The only dicey spot would be around the bandswitch...use care here & deOxit is your friend. Good luck! BTW...National made a walnut-cabinet version of the NC-77 that's a mighty nice looker...would love to find one someday.

Oh, yeah, those tubes are about in the "Dime a dozen" category, assuming there's even anything wrong w/the tubes in the 1st place...
