I began to collect very usable General Radio test equipment over the last 3 years.. Hard to find the rare stuff as it may show up only once each year or 2... But I have been able to get everything I was looking for. The Quality of construction is second to none, and other then the routine restoration some need, once restored the accuracy of the equipment is first rate!!! And most important is they are FUN TO OPERATE!! Cant forget the great documentation available both on line and original manuals!! Robert USA
Hi Robert, great to hear from a fellow collector :-) I dont see that much general radio equipment here in Denmark, but here is another one of my videos : th-cam.com/video/rF7t8RRucTE/w-d-xo.html
This is one reason I like vintage gear, most are blah on the outside, but a work of beauty on the inside! Thanks for the conversion (k~#'s)! ~Jack, VEG
Thank you for showing the inside of the crystal filters. Very impressive construction. In terms of the capacitors, you could replace the inside with equivelent capacitirs; that us if you want to get it functional.
Wow, that's a great construction, everything is massive to survive the ages - that is, except for the capacitors, can you imagine that today someone would put aluminum labels next to the sockets, for example with the inscription QX201-V7 😂 That switch can be repaired beautifully, just find the right material for the shaft. I don't know if the designers intended it that way, but the inner lower support makes a nice bowl for storing parts during service. Nice day 🙂 Tom
there is a huge glass like part in there with golden connectors in the end , the glass is a little bit mate like in the surface, i am very sure it is quartz
@@markocebokli6565 at 17:37 you see the crystal and the blact end parts must be some type of rubber holding the end connection wires, if you look carefull you can see some ultra thinn wires that connects to the crystal
after the video was made we played with it some more, found inductors hand-wound on wooden spools, sorry this is not shown in the video, you got to stop some day
De var der faktisk, men at lave video gør at man ikke nødvendigvis ser alt fordi man er koncentreret på hovedopgaven. Vi andre er så heldige at vi bare kan trykke pause... @@TeardownOZ2CPU
High mass = more stable frequency. One impressive piece of equipment. Thanks for showing us.

I just came home with another funny unit, even older, magic eye, so it is a clear keeper :-) hope to figure out what it can do

good point, and a today model will easy fit inside original casing, make it look original, but work :-)

funny you say it, i did use that bowl for screws :-)
@@TeardownOZ2CPU Love to see it working. Looks to be 1940's construction with that cotton covered wire.
A simple wooden dowel might do, for the knob shaft.
great idea, and add sone of the strong epoxy it will be fine
I guess those "bathtub" filters are not crystal (quartz), but "mechnical", as once made by Collins (I believe).

That is interesting. Is the xtal in the rectangular box in the muddle? Wonder what the "wheels" at the ends are?

Hi this instrument must have been crazy expensive when new!
WOW, it is getting older and older ;-)
Blev lige nødt til at se den igen. Dette apparat er så fantastisk lavet 😄

Ha. This is like an evil version of Bruel and Kjaer gear.
0-16 Megacycles...per second not MHz. HiHi!
exactly how it was back then , cycles,,
