Control Knobs & Vernier Dials

Unless noted otherwise; knobs are black, set screw attachment type
for 1/4" dia. round control shafts.

Vernier Dials

Be aware that most knobs are not new and many are vintage and may be up to 50 years old,
but all are in, at least, GOOD condition. Sizes were measured to the nearest 1/16", however some were
exactly 1/2 way between 16ths so hard to know, for example, if size should be recorded as 11/16" or 3/4".

Missing prices, details and other information often only gets added as enquiries are received, so
Email if additional information is required and I'll add it and get back to you as soon as possible.

Prices are not firm and less is often charged depending on the item and size of the order.
Enquire with a photo if something hard to find is needed as a few other HP & Tek knobs on
old equipment are also available. And if ordering and you have any spare Tektronix knobs
to trade, let me know as I need some that I don't have for some restored equipment I use.
