....not my auction etc..

I have a set of 6 x IN18's from 1971 that have a different pinout from the standard....not sure what to do with them!!

Cheers,

1971?  Truly amazing how long those were manufactured, close to 20 years. I know I have a few made in 1989, and I think I might have some from the early 1990's.

Are the pins in the same physical location as a regular IN-18, just different connections ?

[Nicholas Stock]

Yep, same footprint but different layout....

I would build a clock with connections in the right place - or perhaps build a board which had the right connections and use a clock that drives remote tubes - I have a two tube clock design (and now a three tube clock design) which drives remote tubes, PV Electronics has two boards for remote tubes - a newer one with direct drive - great for IN-18's, you'd just need to take care of the connections to match your tubes.

... if all else fails - I could give them a good home ;-)

It would be interesting to see if these early versions have a decent lifetime.

[Nicholas Stock]

I only have 6 of them, but they should be 'enjoyed' I suppose....not sure if they have Hg or not.

Oddly that seller wont ship to the UK, along with a couple of other countries:

"Excludes: Russian Federation, Belarus, Moldova, Ukraine, United Kingdom"

Has Brexit really made things that bad?!

Not yet it hasn’t but just you wait...:) As an expat, I’m quite frankly appalled at the state of affairs in my country of birth....but politics here in the US is a circus too...but that’s a little OT.
