Just finished rebuilding a KT34 about 2 months ago. I had disassembled the
elements from the boom about five years ago so I decided to go ahead a tear
it down the rest of the way due to the fact that it was an old beam and I
was planning on brining up to current spec.
For the cleaning of all of the internal parts, I went to Walmart and bought
every size gun barrel cleaning brushes that they had. I bought a couple of
rifle cleaning kits to go with it. I connected as many of the rods as I
needed and I was able to clean everything from the clamps to the longest
pieces of tubing. I used a cordless drill and chucked up the cleaning rods
in the drill (very careful with this). This, along with a little WD-40 and
something to rinse it off, will make it shine. Really helps with getting
all the critters out of the small tubing.

I completly dissasembled mine becauuse it was also very corroded but I also
had to change the capacitor tubes and caps. It really wasn't as difficult
as I was told it would be.

Don't bother. I took a parts list to the local house of nuts and bolts and
replaced all of the hardware. The most expensive parts were the 3 1/2 inch
bolts but you probably won't need to replace them. I tried to clean them
with every I could think of including various industrial solvents and it
just wasn't worth it. It was to cheap to just buy new screws.
And after all of this. I put it back together per the manf. instructions
and to my amazement it was on the money the first time. Yes, even 15 meters.
