Helping a friend revive her father's Technics Turntable SL-BD20. We hooked it up to Technics Receiver SA-EX310 and Bose Model 141 Speakers. Plays for a few seconds and then receiver has "Overload" error message. What did we do wrong? I double checked that the speaker polarity was correct. Do we need different receiver and/or speakers? Your help is appreciated.

This brings back memories, lol,. Used to own that same table, back in the day.
I would suggest you check and see where you are plugging the phono cable in...sounds like into a line input, or maybe the Moving coil input, if it even has one! The table came with a stock mm cartridge, which was a high output cartridge, if I remember correctly? Anyhow, I would suggest plugging the table into only the Moving magnet (mm) input if your receiver has such a thing. Otherwise, I think you are simply plugging the table into the wrong input. If the receiver has no phono input, then you would need a separate phono stage...or another receiver with a built in phono stage.

I took a look at your receiver's manual. ( which is online if you don't have access to it). It would seem that this particular receiver does have a phono input. Looking at the specs, it seems that the input has a 0.4mv input sensitivity. That could mean that you are overloading the input with too high an output cartridge. However, I also think that this input is meant for moving magnet only-- i very seriously doubt it was designed for Moving Coils.. There is a 'help' button on the front panel, have you pushed that when the error message pops up?
OTOH, it is possible that your receiver has an internal problem that would need a tech to look at.
BTW, do you know what kind of cartridge is mounted on your BD20? May not be stock!
