Ah, yours uses the eye tube to indicate leakage. Mine has a neon lamp for leakage, and the eye tube is for value and power factor. Mine won't measure inductance either.


One cool thing you can do with one of these old guys is use them for leakage testing on transformers. Wind it up to the 500 or 600v setting and go from coil to case or coil to coil to see if its got problems.

Working in my new man cave is great. The one concern was the lack of ventilation. So I bought a edsyn fx225 hepa filter off eBay. It was a risk as it was listed as not working. Well got it today and apart of missing the pre filter to is complete and working. $150 with shipping is what I paid.

have a look at this listing from same seller, he was great.

I am glad to tell you
it is one of two left in the world
this is a Martin Mars
the photo is of the one that should go to Pensacola Florida air museum
http://www.navalaviationmuseum.org

it has a wing span that is wider than the 747
it was built in the late 30's and was commissioned to flyer troops later on to Korea
7 were built 5 flew and 2 remain

here is a link to the owners site
they were converted to water bombers
http://www.martinmars.com


my brother in law flew these plane for 30 plus years as water bombers. He retired as chief pilot a few years ago

I have not flown in them but that been able to go through both of the planes stem to stern top to bottom
I will post some photos tonight

Drum roll please

Here is a little background
I started my working days as a machinist. Throught this period I built heavy machinery, ships and pulp mills.
I do appreciate good work when I see it!!

So why the rant?
Well I just got a full set of parts from Joe including the new chassis,rev B back plates and rev E control board.
They are so well done I will bow down in respect to his engineering skills. I would be hard pressed the duplicate his work of which I don't say lightly.
Please see the images attached for what we will build in a new thread.

Ps the new back plate fits perfectly in the series two chassis which was to tight in the rev A boards and from the photos you can see the holes aline perfectly at first glance. So don't sell those series ll units short with what Joe's parts can do for them.
