Ok Pete
Q where to have them made ?
The set , Marconi Ocean span 1950's valve
tx needs the big rock's as the
oscillator pass's quite a lot of power
via them ...hc6u are no good , drive level is very low -
the ones fitted are the wired- gold flashed ones ,
so cannot etch into the band ...
the gang want to keep it standard

Hi
If you want to spend a small fortune get them cut. However build a
Mixer VXO from El cheapo standard xtals and or old PMR rocks. Then at your next
rally buy a couple of Screw together 10xj or FT243 rocks of any frequency and
put the El-cheapo xtals inside. And Hey Presto you have Retro
rocks.
I have a small all valve 472 tx that uses 6.00 -6.472=0.472 vxo-able
a couple of kc/s 12ax7-6am6-6cl6= 4wattso/p. Local QRP rig.
Hope this helps
