May not have been cheap, but it adds the icing to the cake!

[Nick Andrews]

Very nice!  And cheap...not!  I don't think I even have that many of those
tubes.  The price has been going straight up.  Have just a few of teh IN-9
too.

Very nice. 

I'm very curious to know what problems you had with the tubes. I hear that 
there's a lot of variation among them. Did you have to buy extra tubes and then 
test them until you had enough that worked properly?

Can you share the schematic for the part of the circuit that's driving the 
tube? I'm always looking for the most reliable way to do that.

Hi Joe

I had the brass work done by an engraving company. Not cheap though! 

Thanks IanV!

Cheers,

Hi Oliver,

Very good job.  Very pretty device! I love the brass work! Did you do the
brass work yourself? If so, what did you use for cutting and etching?

Analogue rules! (says the SW guy)
