I'd prefer to give Tom my business!

Unfortunately I did not know about Tom selling caps. About a year ago I
bought one of the 3FT7 replacements and a set of caps from the same German
supplier. They have been working out great.

I have seen some homebrew attempts at cap restuffing and then to use epoxy
to glue the can back on. I had decided that was a route that I did not want
to go. Nor did I want to spend $60 on some 1960's vintage of an NOS
capacitor from Surplus Sales of Neb.

I did buy the balun and will try to quantify it's performance on a network
analyzer once it arrives. I would be interested to see just how linear it is
across the .5 to 30 MHz range. Many of my low frequency baluns are wound
with Litz wire but I doubt that this balun will have litz windings and I
have no idea what core they are using. There does not appear to be a way to
take it apart.

----------------------
I just get "so" excited when someone makes a shiny new part for the R-390A.
Of course I am not going to jump out of the canoe to buy the burnished,
polished aluminum one that is up on eBay. I am not that much of a crow <j/k>
for collecting shiny tidbits in my nest.

My latest infatuation has been with Racal and WJ stuff (I know, traitor!). I
am still chasing that mystical <140 dBm noise floor demon. The RF-590 "has
'spoilt me", now I just want to find a RF-1310 to pair it up with.

I have now officially run out of rack space in the console. For anything
else to fit, something else has to go. The floor of the lab would not take
any more "stuff" without me fearing that it collapse down into my dining
room. It has since lost it's designation as a guest bedroom as well, the
sofa bed has to come out.
