I bought this radio earlier this year and recapped it. The volume pot doesn't turn completely off, which is apparently why a previous owner installed a switch on the top. I don't think it distracts from its appearance, and it works quite well since the volume control still works perfectly with no noise. It looks like the rotatable antenna wasn't used much since the antenna wires look good and don't seem brittle, if that's an indication. Recently the vernier tuning has been slipping a little but not too badly. I did lubricate it when I had it apart. The electrolytics used originally were:

2-100uf
50uf
15uf
5uf

In the last picture you can see the four antenna "lugs" that unplug for servicing. Fortunately Zenith put the antenna trimmer screw facing the pcb, making adjustment possible with the antenna wires attached, and can be done with the radio in its case for alignment. The reception and audio are excellent with the 9 volt chassis. This has gotten to be one of my favorite radios.

Thanks for the interior pics, ZR---have not seen one of these early 755's in person. Think the engineers were eyeing Motorola and others who offered the "handle antennas"...

I have the next version with internal ferrite-bar antenna and it's also an excellent performer. The rotatable handles are great for obtaining maximum signal level without moving radio, but not good when you are carrying radio while listening as your hand affects reception...

You could probably remove and repair the switch on volume control. Have removed them for cleaning and it just takes care & patience.

Thanks John. Yes the antenna reminds me of the Motorolas. I wouldn't suggest carrying it by the handle in case it ever cracked, there goes your antenna. Even more so with the Royal 2000. I hadn't seen any of this model for sale on Ebay until this year, when a few showed up.

Nice looking radio, I really like the style of the antenna.

I picked up a 755M in July at a thrift store for 18$, and it worked fine without a recap. I cleaned it up and it is a great radio, great sound with a switch for hi/lo tone. It was missing the faceplate, however. So John sent me some pictures of his to print out and laminate, I am still working on it though.

I was given about 6 of the early Motorolas with the antenna handles, I guess no one wants to work on them because the wires break easily. Not sure what to do with them, especially since some of them look like they were recapped in the past...

I enjoy your threads. keep it up,

Henry

Oh, Also got a maroon zenith royal 300 off eBay. I saw your thread on yours including your white one! I Will post pics when the restoration process is done.

Post a FS ad in the classifieds here, Henry. Use eBay closed sales as a reference on asking price, and maybe add, "OBO" after it.
You could offer them separately, in two or three groups, or all in one group.

Thanks Henry. The 755 series radios are essentially the same performance wise, except for the 755M/74. The M version has a bigger radio sound, most likely because of the acoustics of the bigger case it's in. More bass and a very slight increase in sensitivity that's only noticeable with the weakest of signals. After recapping it, it's only necessary to turn the volume up an eighth of a turn to get strong audio.

What I like most about the Royal 300 is it has excellent tone quality for music. I used mine to listen to "Wayback Wednesday " on WSM for quite awhile every week.

Thanks for keeping the spirit alive. The inflation calculator tells us $80 in 1960 is $739.37! And worth it too.
