Nice intro to the Rider Chanalyst. I picked one up and am new to vacuum tube radios. I am putting together a work bench and my first projects will be to get the old test equipment fixed up. I am aware of the hazards and ready for a fun new hobby that was a long time coming.
Cool boat anchor. It would take a real long time to fix her up. Paper capacitors are tough to replace but doable. Five pieces of test equipment in one case. I did get a lot of downloadable stuff on the internet on it to read through. Quite a great unit for it's day!👍🏻
What a fantastic piece of kit! Thank you so much for making & posting. I like your probe capacitor - it's better known as a gimmick condenser & was very common in the 1930's - 1940's. BTW Phil of Phil's Old Radios has one of these & there's a write-up about it on his site. Thank you again.
Very interesting piece of test equipment, I was not aware Rider made any hardware. I always associated Rider with publications and teaching. Thanks for this look at it!
Thanks for the reminder. I used an overlapped piece of insulated wire(next to but not touching the conductor of the coax) as seen around the 14 minute mark of the video since you cannot find a 1-2 pf component capacitor. I adjusted the overlap until it measured a little under 2 pf (2 mmf to those of us old enough to remember the former designation). Of course, you can make it as small as you like by reducing the overlap but a little under 2 pf worked fine for me. I had to build the probe since it did not come with the used Chanalyst and I could not find anything like it on the web. It took a little experimenting since my first try (with the smallest component capacitor I could find) was too large and loaded the circuits of short wave sections (I tested it originally on a 1938 Philco AM/SW radio. A bigger capacitor will work OK in the AM band, but you need 2pf or less as you approach 20 MHz (20 MC in the old jargon). Of course, you need some capacity to get enough signal into the Chanalyst, but it has a lot of gain so you don't need much. I hope others will try to resurrect one of these old RCA units and let us know about it on RUclips.

Greatest Advance Ever in the History of Radio Service ! :-)) The humility of marketing.

If it helps anyone, page 1 of the manual on BAMA [pdf page 13] upper right paragraph, states the RF-IF probe [red] cap is 1.0 micromicrofarad [1pF].
