Rca 730-tv1

[vts1134]

Capacitor soldered to the right place and . The only lingering problem is the tuning string and needle indicator are not inline with the station. Minor fix me thinks and I'll be 33.3% towards a working set! Speaking of a working set does any one own one of these? My set doesn't have the original turntable and the Sams doesn't even mention the phonograph. Does any one know a chassis number, or any insight they'd like to share on the subject?

Have you seen this restoration project on the ARF ? http://antiqueradios.com/forums/view...p?f=3&t=136261

famous last words eh? The problem isn't a misplaced tuning string or needle as I assumed it was. The tuner needs to be aligned, not a job for a rookie. I'll have to take the chassis to my local antique radio service man. 33.3% will just have to wait a little longer.

Since the cabinet was too large to take to the local antique repair shop and the radio dial is on the cabinet I had to mark the back of the dial plate with frequency references.

The AM needed almost no alignment whatsoever but the FM was totally off. 107.9 showed up all the way down around 94ish. The problem turned out to be an adjuster that had gone open. The part was screwed down and then glued on top of that making it's removal impossible so another was soldered in to do the job. You can see the old one desoldered on towards the bottom of the picture and the new one closer to the top.

After some tweaking the tuner is aligned perfectly and sounding fantastic. Another nice thing about taking the unit to the shop was getting the chance to learn from an expert how to do the procedure myself next time. One other thing he mentioned to me was that I did a very good job on the new caps, but that I should keep the leads on capacitors as short as possible. I didn't ask why at the time but now I'm curious. Was this just a personal preference or is there a real reason for this?
33.3% is almost here

I try to keep the leads as short as possible or as colse to the original length as I can.
Makeing the leads longer than original can introduce problems such as signals being capacitively or inductively coupled to places they shouldent be(through the leads), adjustments being thrown off, and increased chance of the component leads shorting to adjacent wireing.

That is my 0.02$.

Hello vts1134, Would anyone be interested? I have a 730TV1 in fair condition that may be a parts set. It never saw water and is complete. It was in a storage building for 30 years. I remember getting the radio to work but the TV part is a challenge with the B- and chassis ground not being the same potential, etc. I have way too many other restoration projects.

Cheers Dave 63

Great thread here. I have the 730TV2 version. Very similar to your set. Believe it not, my set works, both TV and Radio. I will definitely restore the whole thing before plugging in again. Interesting set and has channel 1.

I enjoyed the Youtube post.

Thanks

[DavGoodlin]

Channel 1, was that on the TV1 also?

I started to restore the 730TV1 when I was 16. The radio worked great, but the TV was a very intimidating restore and I lost interest. I must remember, there was no VK back then.

When I got my 9PC41 projection set, I realized I would never restore the 730TV1 and had to choose. So I sold the TV1 to another member...

[robertnjax]

I think that it has channel 1, but not sure.

[robertnjax]

Update: Yes, My TV2 has channel 1. Just got it home from a climate controlled storage unit. Looks really nice. Will be one of my first restoration projects.

[DavGoodlin]

That's a very nice set. Is that a KCS 27 like the TV1? My 721TS has the same chassis but is a KCS26. I am just starting to restore that one.

[robertnjax]

Mine is a KCS-27

wow that is a fancy looking combo.
