    Most of the time when I had to repair super-pricey lab devices I found
    ratehr mundane parts in there. Occasionally "dremel-trimmed".

    BTW, yesterday my wife treated me to a nice bottle of "La Fin du Monde"
    from Unibroue, from your neck of the woods. Very tasty! Just make sure
    not to drive after a few of those.

    Hm... a 9% Quebec "beer". Never heard of it.. too many and it really
    will be the end of the world for you.

    I thought that some of those smaller feedthru filters used
    cylinder/coaxial ceramic caps inside.

    And speaking of not driving, try this:

    This is double-fermented beer, which is very fizzy and has a slight
    champagne taste. It's very alcoholic and absolutely delicious.

    Elderbrat is moving to California (finally got a tenure position, in
    Fresno) and we're taking her to the Monk's Kettle tonight to
    celebrate. They have 20 beers on tap, including a bunch of Belgian
    stuff. The gourmet wine thing is rapidly being overtaken by a gourmet
    beer fad. They have one bottled beer that's $24. The St Bernardus
    prior 8 is about $9 on draft, and worth it.

    Some might but the ones I saw didn't. We learned that trick in the old
    ham radio days when we needed a dummy load resistor that goes to a GHz
    but the bank account said "no way". Stagger a whole bunch of parts in a
    nifty way on strategically placed copper snippets so it all stays
    resistive. Of course nowadays copper can cost several bucks a pound,
    this was in the 70's.

    Nice. I love it when beer bottles have a cork and smoke wafts off after
    popping it out.

    You've got two daughters? I thought you just sent her to Cornell but I
    guess that must have been the younger one. Honestly I don't know what's
    the appeal of a tenure track job when dad owns a nice high-tech company
    smack in the middle of a city with tons of nice pubs in walking distance.

    Yes, two. She's a botanist and a certified BMW motorcycle mechanic.
    She makes motorcycle tours of the sw USA and northern Mexico,
    discovering and naming new species of plants and their co-evolving
    native bee species. Involves DNA sequencing and wet stuff like that.
    Not especially interested in electronics. We do have a shared interest
    in beer. Her rule is "one beer per wheel."

    Wow! Now that's a combination.

    I wouldn't apply that rule with this stuff:
