Spaced Command ?
I have a Zenith TV that if a CRT becomes available for I plan to restore . Just for kicks in the meantime I recapped the two electrolytics and the 4 or 5 other paper caps in the space command chassis , and got it working . Sort of . The thing is , it will change the channels just fine with the channel button on the 8 or 10 working space command clickers that I have (I "inherited" a box of about 20 different mfg's clickers when I got the set) , but , not a one of the seemingly working Zenith clickers will activate the on/off volume function . All voltages on all tubes are in spec with the sam's using my trusty ol Simpson 260 . Ok so now here's the real puzzling thing , I have one Admiral clicker that WILL activate the on/off volume function just as pretty as you please with it's on/off volume button , and will do it at the same distance (about 30 feet from the TV) as the Zenith clicker will do the channels ! Obviously it's now a tone issue , something's not right in the receiver that its causing the on/off volume to respond to the different frequency of the Admiral clicker instead of the Zenith , do you think I'm on the right path here with this reason ?. Having just a sams , with no troubleshooting or adjustment instructions for the space command , I have no clue how to get it listening for the Zenith instead of the Admiral clicker on the on/off volume function , anybody got any info or knowledge about these systems to give me some tips/advice here ?
PS , I say "clicker" instead of "remote" cause that's what we called them back when they were still in use . The term "remote" seemed to have come in when they went to the non clicking electronic remote controls ... |

Got a model number for the set? Hard to pull a Sams without it....

My apologies , Sorry I forgot that , the TV is 16F25Q and the remote chassis is S-48583 in Sams set 523 folder 2 .
Here are a few pictures of the set in question |

The two coils mid-chassis on the remote chassis determine the receiver frequencies for the two functions. If you can figure out which one controls the on-of, you can "rock" the coil slug core about a 1/4 turn at a time to see if it will respond to an on-off tone from the transmitter. Be sure to use the correct SC remote - the chassis should be a SC 300 chassis, so try only with a 300 remote.
