Turns out we got a remote roundie! Hmmmm...

[SueAnders]

As mentioned on the other thread the sellers unexpectedly at the last minute were able to arrange a meet up for delivery. We're pleased and concerned at the same time, because it turns out it's a remote set and we weren't smart enough to ask that question in the first place! They seemed pretty rare back in our days of youth so it never occurred to us that it might be!

So now we're trying to find out what Space Command came with chassis 25MC33? The prices for those on eBay range from not too bad to frightening!

Here's some pics of our new baby! She'll come out of the cold and into the house as soon as our big strong son can help us out!

hope the "cataract" isn't too bad, and what does "all channel" mean?

That is the tuner cluster. which includes the tuner motor. It is not the remote chassis. Can you take a pic that shows everything in the back in one shot?...Preferably center the camera on the CRT base then walk back until all is in the frame. The remote chassis on Zenith color sets of the era is usually about the size of the HV cage and black.

All channel means it should have UHF.

I see two flat lead wires coming from the aerial connection terminals on the back. This would indicate the UHF tuner is installed.

Good looking set. The 25MC33 is a great chassis. If the tube is strong, you should get a great picture out of it. Don’t fret over the lack of UHF. Yu will likely be using a converter box or other signal source which outputs on VHF. since the digital transition, the lack of UHF tuning is not the drawback it once was. I would not worry about finding a remote until the chassis and cabinet are fully restored then you can add that feature last.

Before you worry about the remote, take the back off, post a pic and show us that it actually has the remote receiver chassis. Zenith made sets with pushbutton motorized tuning that were NOT remote ready. If you don't have the remote receiver chassis in the set then having the remote will not do you any good.

That is the zenith style cataract, not hard to fix. I had a video on my photobucket account, but after photobucket went ransom mode I can't play it, or embed it here...http://s1095.photobucket.com/user/El...?sort=3&page=1

It's probably a good thing it's not a remote model; less complicated and less to go wrong! With with the motorized tune, how do you change the channel, is there an Up and Down button somewhere? There's nothing visible on the control panel.

The tuning knob is solid, there doesn't seem to be a clear window for the channel number to shine through. So it would come through the wood-grain? That seems kind of odd!

We're kind of scared to plug it in and turn it on, my hubby's experience is limited to minor car re-wiring, a few old stereos and clock radios with tubes! As they say - first do no harm!

Probable that the front VHF knob is the VHF channel up/down motor rocker switch. If it moves a few degrees one way or the other and no more, and also wants to return to one center position then that is your motor control. The back knob is an auxiliary manual VHF knob. Go with the back VHF knob for now. The motor shaft extends (and turns) when powered to mesh gears with the VHF tuner shaft (much like a car's starter motor). The shaft is greased and the grease tends to turn to glue...If you do not free and lube the motor shaft before powering the motor then the motor won't turn and will stay powered overheating it and risking damage...

Since the chassis was powered recently to take that screenshot it should be safe to power again for monitored tests shorter than 5 min.
Zeno advised you on grarscale/screen/G2 adjustments a while back...Might want to do that to check your CRT.

That's good to know!

WiscoJim suggested that we obtain a "SAM photo fact 757-4".
I did a web search and the main seller of them "schematicman" doesn't have that one available (of course!), and I couldn't find it on eBay or elsewhere. Does anyone know a source for an original copy? We have trouble reading reproductions of things, and I just found out yesterday I need to have cataract surgery (the eyes, not the TV screen!)! Too much sun over the years. Any suggestions on the SAM thing is appreciated!

You can buy Sams Photofacts directly from the publisher:

If you live near a large public library, it's worth checking with the reference desk. Some libraries have subscriptions with Sams that let their patrons download any Sams manual for free.

Thanks Phil!
I read somewhere on another radio forum that the SAM from the publisher are expensive and are just sometimes rather iffy copies, so we would prefer an original one if we can ffind it. My hubs says he got one once for a radio he worked on and it helped him a lot.
