Sears Professional Series Amplifier and Tuner

apparently there isn't a Sears only manufacturer listed so I am forced to show these units under Sears LXI category. I have both these units the Amplifier Model AM-4658 and the Tuner TR 6658. They both perform exceedingly well - I have heard that they may have been made by Sansui as they look very much like their black faced units.

Anyone have any information on these units . Eg Schematics and manuals?

Perhaps this is not the best location for this comment but ...
I found Sansui gear made in the 1980's was terrible. Those single pair output TO220 transistors would always smoke at full level usage at 30 minutes or more. They had a shorter life when two pairs of speakers were connected. Their gear from the 1970's was really good. There is so much gear made with no love, no love at all. I fixed that gear again and again as a technician.

Also I forgot about LXI gear until I read the above post. Brings back memories. Mostly bad...

Re: Sears Professional Series Amplifier and Tuner

Firstly, which Japanese hifi manufacturer made the first black-faced stereo component is still a subject of debate and does not instantly constitute a 'Sansui rip-off' -- although it may seem that way with so many of their hifi components of the late 70s and early 1980s sporting one. Secondly, hifi components made in Korea were not necessarily inferior to those made in Japan, but this myth continues to be promoted by those who flog old hifi equipment of the 1970s, 80s and 90s as 'vintage stereo' components. In that marketplace Sansui's AU line of power and integrated amplifiers are considered to be some of the very best from that era. Unfortunately Sansui's management were not as good as the AU line itself and their failure to successfully follow up on this line ensured their loss of the North American market share to Japanese electronic giants that manufactured many of the electronic parts that Sansui amplifiers relied upon but could not build themselves. Thus began Sansui's slow and steady slide into irrelevance and eventual oblivion when it was purchased by a Chinese company along with the once proud names of Akai and Nakamichi.

'Made In Korea' did not automatically mean an inferior hifi component. The biggest Japanese hifi makers were faced with the decision to either drop hifi components from their line altogether or build assembly plants in neighboring countries where the availability and cost of skilled labor was much improved from the situation in Japan. Sadly, the Japanese experience saw an aging and increasingly scarce workforce of assemblers drying up simply because their university-educated children considered such a job to be 'beneath them' and akin to that of a mere laborer. Facing this reality, Japanese companies that decided to stay in hifi manufacturing had little choice but to move assembly offshore so the first stop for them was Taiwan with Korea being a close second. It must be said here that the quality of hifi components from these countries were still very high during the next five years or so for three reasons: 1) the decision to use cheaper materials had not yet been made, 2) virtually every part module that went into their hifi components was still made in Japan, 3) and the first offshore assembly facilities were constructed, controlled and supervised by the Japanese hifi companies themselves to ensure their patents, processes and QC were tightly controlled.

As to Sears and their stereos, the closest corporate ties Sears established with a Japanese electronic giant and hifi manufacturer of the time were with Mitsubishi -- which later sold their own hifi components direct to Sears complete with the Mitsubishi label and logo on them.

Re: Sears Professional Series Amplifier and Tuner

Thanks for the info...I must say though that this amp and tuner are very well built and the tuner is one of the best I have...I have been in electronics for 42 years and have Pioneers, Akai and Technics equipment and some others but I love this pair very much..just wish I could get some manuals for them,,

Many regards
Paul

Re: Sears Professional Series Amplifier and Tuner

They were not made by Sansui , I guess you could say imitation is the highest form of flattery or you could say Sansui rip offs . Sansui was made in Japan . The Sears were made in Korea by a company called AGS . Google Audio Reflex and AGS stereo , you will mostly find receivers but that's them .
