re: RS-440

Would like to hear from RS440 owners about any LOUD pops when the audio mute button is pushed within a few minutes of power on.

RS 440 serial numbers starting with 1xxxx are LR5555 with minor differences
RS 440 serial numbers starting with 2xxxx are LR5555A with minor differences

The change for Setton was between July 1977 and December 1977 derived from internal date stamps on units I have serviced.

The original Audio Mute circuit (RS uses a separate board) R1 &2 (R45 &46) = 860K
The 2 /A version use 56K

I piggy backed a 56K on back of the original Setton board and basically killed the POP.

I also noted the POP disappears on it's own within a few minutes of operation. DeOxit has no effect.

Still Begging for a GOOD COMPLETE scan of the RS Schematics. Those floating around are missing a bit of the center. PLEASE post on HiFi Engine and message me!

re: RS-440

I just purchased a mint Rs-4040 and must say that it is a performer ' currently using a pair of sa-7070 technics liner phase speakers and it pushes them with no problems at all , definitely underrated in the output wpc as stated in other articles .

re: RS-440

I have a Lafayette LR-5555A receiver, while looking for the manual online I found a person who worked for Lafayette in the 1970's and said this receiver was made the same as the Setton RS-440. I hope this helps someone else looking for the Lafayette LR-5555A manual.

re: RS-440

I have one I just dug out of closet... It first powered on but now does not do that... hopefully this manual will help me get it running again. Thanks for the post. Did this help get yours going?
