Some quad equipment from the seventies had an FM Multiplex jack that was meant to connect to a quad FM adaptor (demodulator) when the anticipated quadraphonic standard was approved. Early sixties FM receivers had a similar jack for connection of an FM stereo adaptor. Often called FMX. I guess it's it's called FM Mono on the DC6100K as the full baseband (stereo and all) are left unprocessed?Ive just got the FM radio working again on this unit....TR103 was replaced.
Now Ive got another query - hoping someone can identify...on the back of this DC6100K is an 'FM Mono' RCA Socket.
Anyone know how this may have been utilised?
Interesting thanks par4ken ...Ive been looking at similar Sanyo era receivers but could not find another with this. I thought I would be able find one that had a SM to understand where the signal is taken from in the FM circuitry.Some quad equipment from the seventies had an FM Multiplex jack that was meant to connect to a quad FM adaptor (demodulator) when the anticipated quadraphonic standard was approved.

It would include mono audio with the 19 KHz pilot tone and the modulated stereo difference signal, 38 kHz double-sideband suppressed carrier (stereo difference signal) riding on top. The high frequency stuff would not be audible but would not be good for your tweeters.Interesting thanks par4ken ...Ive been looking at similar Sanyo era receivers but could not find another with this.

This query is an afterthought as now the receiver is back in the system...otherwise I would have traced where the signal is coming from on the FM board.
So when we say unprocessed signal - wonder if its possible to directly amplify it and what on earth would the result be!
This unit does not have an FM Stereo to Mono Switch and it would be nice to have a mono option.
I haven’t checked to see if there are other responses, but typically that jack is the raw FM signal without the multiplex decoding.Ive just got the FM radio working again on this unit....TR103 was replaced.

Hey jipop..Actually I couldn't help it and did try it on old test amp and speakers and indeed it worked...it was no better and slightly worse to the ear than normal output. I think I could tell that there were higher frequencies in there. Certainly not just mono and no improvement help for stereo stations that are not that strong of signal.
Nice radio. I didn't know Channel Master sourced radios from Sanyo. I had a CM clock radio that was very cool with reading light attached and an extension speaker with volume knob on it. Wish I had kept it.Hey jipop..
I don't have anything actually useful to add, I just want to say it's been an interesting thread and you must have advanced electronic skills. It's been good to see the Sanyo name out & about. Before they were swallowed by Panasonic they were quite the powerhouse.
The first piece of my own personal audio gear was when my dad bought me a 6 transistor Sanyo AM radio:View attachment 87337
He called it Japanese junk but I loved it. I was maybe 10 years old & it was small enough I could cram it into my corduroy pants pocket. I'd take it to school & run the wire from the ear piece inside my shirt to the radio in my pocket. So I could listen to AM radio top 40 instead of History in class. Yeah, I was one of those kind of kids.
I'm glad you have enjoyed this thread.Hey jipop..

Hey Mate,Hello to all in the Forum my First Post!
DC6100K
I have just picked up a Sanyo DC6100K all in one here in Australia- for a few dollars - its not in working condition (fuse blown) and so far working my way through the Power supply electronics...yet it would be very handy to find a Manual - even a user manual may have the Schematic.
Im finding the power switching illogical and would really like to check switching path from reference.
Please would anyone have a manual they could share!?
Thanks in Advance
