It is model M660A and is a 5 tube AC powered superhet covering these frequencies in five bands : LW 150 to 400 Khz; BC 500 to 1600 Khz; SW1 1.6 to 5 Mkz; SW2 5 to 15 Mhz and SW3 15 to 30 Mhz. Two tubes serve two functions so it has the strength of a 7 tube receiver. This Model M660A was probably the last of Zenith's tube and hand wired receivers made. And, it is all American!

The quality of the design, layout and wiring equals if not exceeds their line of Trans-Oceanics. And, the performance of this receiver is outstanding.

There is a built in ferrite rod antenna mounted on the rear, works O. But if you hook up an external wire antenna say around 60 to 80 feet, you'll be blown away with the amount of signals this set receives. Was very dirty, so it remained untouched in a cardboard box until an article I read about the M660A piqued my interest... Maybe that's what's in the box.

I had relegated this radio to the likes of the Hallicrafters S-120 and, boy was I wrong! Once it was cleaned and the crud removed, a jewel appeared. It is enclosed in a all metal cabinet wrapped in a vinyl grain material.

The chrome front edges were polished and now displays it's original sparkle. The wrap around metal cabinet slides easily away from the chassis allowing full examination of the circuit. Just take a look of the hand wiring the my photos. All the original filter capacitors were replaced with new electrolytics. All the capacitors are now ceramic drops or ceramic discs.

Both dial lamps were replaced with new # 47 bulbs. All the tubes were tested and all test "good". All controls were chemically cleaned and moving parts were lubricated.

Four new rubber feet were attached to the bottom of the cabinet. The alignment was performed following Zenith's instructions. After the IF transformers were tuned, it was then necessary to align all the five bands. The alignment procedure requires adjusting paders and coil slugs for both ends of the designated band.

And then, repeating the process for each band. Not complex but, as I found, easy to get mixed up. Also was good idea to let the signal generator warm up for a few hours to get real stable.

Overall, the alignment came out perfectly. Audio is crisp, no hum and as loud as necessary without distortion. This radio is an outstanding performer. I mean tons of stations were blasting in from all over the world. Some type of signals were heard on the LW band.

Lots of broadcast stations on the BC band. Ham and foreign stations on the SW1 band, but, the SW2 band is where all the action is. Plenty of foreign stations to select from. Some in foreign languages, some playing music and some in english. Then, the SW3 band had more foreign stations and a few CW(morse code) ham stations were received.

This radio has features others don't have: the band spread.. Adjusts sensitivity and a stand-by switch to cut out the receiver. Also on the rear is a headphone jack. So, if you like to listen to short wave radio stations don't pass this gem by. This radio is a performer and has been perfectly aligned.

You'll enjoy it for years to come. The item "EXCEPTIONAL VINTAGE 1966 ZENITH AM SW TUBE RADIO 150 KHZ 30 MHZ UPGRADED WORKS" is in sale since Thursday, June 11, 2015.
