Sears - LXI 564.92580

[Super Noob]

Pulling out the BOTL stuff to purge.

Was on quest at the beginning to go and collect store brand equipment. Have units from the shack, penny’s, and sears. This was before I got ahold of the good stuff.

Anyways this unit had not been on in over a year. Decided get lamps replaced today - I glanced at offset = one channel was over 200mv and the other around 30mV.

As this things has STK-00050s... no offset adjustment. Found some bad caps... changed them and this Sanyo special is now back to under 5mA on both sides.

All LEDs now... it is different but I like the looks. The STK unit sounds pretty good now that it is dialed in - surprising to say the least.

Anyways share your comments on this obscure dude.

Little better pic shot I rotated.. Nice cosmetics

Yeah - It was side standing while I was working on it.

Changed tone control caps... those blue Sanyo had pretty much become resistors (high ESR measured on my component tester).

Clean sounding unit now.

Just went back in and changed the rest of the electrolytic caps...

FM Board:

Main Filters:
(upped from 6800 uF to 10,000 uF)

Switch Board:

68 uF were replaced with double 33uF.

Looks nice.
Wish I had your skills.

BTW-- DC offset is a voltage usually in millivolts not milliamps..

You are right... mV. Typo.

I worked PT for SEARS service dept.( Div. 57 ) back in the early 90's. In Mary Ester, Florida. Just before Desert Shield/Desert Storm. Worked on a lot of the LXI pieces.

Sears is soon to be gone. Thanks for your service.
