[Central-Electronics] crystals

[K6JEK]

Does anyone know the specs for the crystal oscillator crystals, like 
capacitance?   I would like to buy a couple of them but only know the 
frequencies and size (HC17/U).   Crystal makers want to know more.  I 
would also like to buy a 5.605 MHz crystal for my most common rag chew 
3.895.

Almost all FT-243 crystals had the same capacitance (what was it, 92 
pF?) but I wouldn't put it past CE to use something fancier in the 100V 
HC17/U crystals.

Thanks,

Jon

PS:  Why am I buying crystals?  I was going nuts trying to get the 17.5 
MHz crystal to oscillate and be on frequency.  Then I noticed the last 
guy who worked on my transmitter, Wes Schum (yes, Wes Schum), noted 
this crystal was off frequency & he didn't have a spare.  That was in 
1970.  I doubt that it's gotten better in the interim.

Incidentally, I found adjusting the slug-tuned inductors in the HF can 
had a big effect on frequency while the screw adjusted inductors 
outside didn't do much.
