Hi Roger, to me, hefty means it can be picked up by hand but elicits a
"grunt" in the process.
Ameritron's largest transformer is used in the AL82/1200/1500 amplifiers.
My AL1500 6m amplifier has a self contained Dahl Hypersil transformer that
weighs about 30 pounds or so. It will run the 8877 all day long at 1500w
out on cw with no problem.
The complete amplifier weighs close to 80 pounds and is just about the
limit for what I can handle unassisted. Other homebrew amplifiers for VHF weigh
even more and need repackaging to have the power supply in a separate
cabinet
Beyond this, transformers will move into the ultra hefty category,
requiring a really firm grip and a more emphatic "gruuuunt" and mumblings about
a
bear's backside anatomy. This is my personal limit as there is no room for
an engine hoist in my shack!
Considering that some tubes we use have handles, maybe we need transformers
with handles (and wheels) as well!
