The last time i saw a price they were over US $1 each, but that was over
30 years ago and for military use. Between the now rabid regulation and the expected cost i would be rather surprised to find them in commercial instrument amplifiers. Of course with Chinese manufacture such bets may be knocked into a cocked hat.josephkk Inscribed thus:
You mentioned "military use", the original packing had "Marconi" on the label ! I've had them for more than 20 years. They came as part of an auction lot. If I recall, a subcontracting company that went bust when Marconi was taken over.

So these insulators would likely be fitted in the USA. They obviously were not made for the job, wrong cross-section area, unnecessarily thick, hole not used - perhaps they just had them laying around. That grey silipad could have been used with FET legs preformed to accommodate.
