  My nephew at the time was about 7 or 8 years old and was always curious about my shack and the radios....he  reached into the chassis while it was on.  Fortunately, he didn't touch anything hot HV wise but he got a piece of my mind. 

My 8 YO daughter loves the shack and all of the "thing a ma bobs" (her term) aka resistors, capacitors meters in a radio. One day when I was working on a BA xmtr (700V) she reached up to touch one of them. I gave her a stern lecture about HV and the dangers of a shock if one is careless. About 2 minutes later I touched the B+ while grounded with the expected physical reaction. "Oh she said, you mean like that."

Dave - most definitely kewlbeanerz. I got wood just looking at it!

I got wood too. Used it for the next tuner....

Dave,
       FB on your use of the "wood". Whenever I see a nice homebrew balanced tuner like you built it turns to "granite"!

"It that N4VMY's transmitter?"

Yep, that's the one he uses to jam AMers who dare to operate on 3875.

I called CQ a few nights ago on 160 and he answered me with a great signal into Sulphur and he was a pleasure to visit with for almost an hour.

That's the AM N4VMY. He is active in church and an all around nice guy.
The other N4VMY uses another mode and often fires up on top of AM activity on 3875.

With my luck, I'd have a sneezing fit while trying to load that sucker up and pull it off the wall and onto myself like a high voltage fishing net from hell.

in the middle-late 20's es very early 30's there was a major debate about building rigs with wood or metal. many swore that they would never build a rig with "death dealing" metal frames because of the risk of getting across something to ground; wood was also cheaper. Many of ur rigs in the time period 1925 through about 1932 were built in place like furniture and constructed on the spot they would stand out of wood with fixed shelving in place. The use of wood also made circuit changes easy. Finding a good ground could sometimes be a problem, or I should say NOT finding  ground loop of some kind. Cheesy

I'd say until the advent of the rack and panel job where you could buy commercial racks and panels which started around 1929 (IIRC) most ham tx's were built with wood frames and shelves. Certanly before the widespead advent of class B modulation.
