Title: Free glass crystal Post by: W7TFO on July 13, 2011, 02:36:15 PM Yep, it is all glass. I've not seen but one other of these, was used in a BC FM exciter.
Cut for 88.3 MHz. More or less a HC6/U size. Free to the first ham that can tell me how it will live again.

It needs to be in a glass case on display in some radio museum somewhere.Thanks for sharing that with us. 73s Mike

I have several from BC rigs that are glass-envelope octal based jobs, same size as a 6146. I suppose the vacuum surrounding them eliminates any oxidation or corrosion of the metallic plating, and adds a bit of temp stability like a thermos bottle. :-X 73DG Title: Re: Free glass crystal Post by: kg8lb on July 19, 2011, 05:04:49 PM That is a real beauty. Would look fine in a breadboard educational crystal ascillator circuit.
I could use it in my pirate FM transmitter ! ;D The PLL died and the TX went QRT after 20 years continuous 24-7 service. Seen quite a few of the miniature tube version . The HC-6U glass is fairly uncommon IFAK. But I don't really need the crystal ;) Title: Re: Free glass crystal Post by: W7TFO on July 19, 2011, 10:48:06 PM Well, send me your addy and it's yours! ;D AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
