Found Great Grandpas Workbench WE500

[JorgeAmely]

From the bottom photo, it appears the screw that should hold the tube in place is missing, so it's probably already been converted to a 500 -- just not marked.

Paul, what would one look like? I was looking over an old print out and as a corrective measure, "replace tube." And I was wondering which model would have one?

The tube in question is a Western Electric 426A. Here is an album of one in action:

Jorge, for some reason those Google links aren't working.  I don't know if the viewer has to be logged into Google Picasa in order to view them or not.  I had some trouble viewing one of my albums recently as I wasn't logged in to Picasa.

Nice!  I learned a couple of tips from your pics.  The hair dryer w/baggie trick (I've only been using hair dryer by itself) and the part about squeaky-clean electrical contacts improving voice quality.  How do you get all the terminal contacts so clean and shiny?

I take it the links worked for you, Greg?

Yes, no problem with the links from my end.

If could be due to Google's world domination plans that require you to be logged in into some form of Google software in order to see other stuff from Google's servers.
