This is an attractive, vintage AM/FM receiver... I really like the look. I acquired it a while back and did minor refurbishing... including lamps. Mine works well... just got it out after several years in the crawl space! I plan to donate it to a friend just getting into vintage Hi-Fi.



re: STR-6046a

I just picked one up at an estate sale. All channels work but A and B won't work simultaneously. When I push in both, everything goes off. Is that just how they are or I could it need fixed?

re: STR-6046a | Speaker switches

If you only had loudspeakers connected to just one set of outputs (A or B), then yes, this is correct operation. When both A and B loudspeaker switches are engaged, the outputs are series wired to assure load impedance is not too low. This switching method is common on many Sony models from the era, both receivers and integrated amplifiers. Only side effect of the design is that which you experienced: engaging both loudspeaker switches with loads connected to only one set of outputs results in no audio being produced.

Sony STR-6046

Essentially a duplicate of the lower-priced, lower-powered Sony STR-6036/6036A, but with enhanced power, a hi-filter switch and a mic mixing option.

Besides providing 20 watts per channel at 8-ohms (compared to 15 watts for the 6036/6036a), the 6046 allows for the MIC inputs to be mixed with any other input source (AM, FM, Phono or Aux). Because of the 1/8-inch input jacks, the user would need appropriate adapters for mics using 1/4-inch plugs (or some other connector type).

An outboard mic mixer of any type can also be connected to the 6046's jacks.

During the 1970s (and into the 1980s), Radio Shack offered an attenuating patch cord that dropped hi-level signals down to mic level. Two such cables, along with appropriate adapters, would allow hi-level equipment to be used thru the MIC jacks.
