When working on a power amp outside of its case and of the normal
form with mains transformer at one end and output matching
transformer at the other.
Assuming the valves don't extend too far.
Aluminium sheet about 20 inches by 5 inches. Bend
down the middle lengthways to a right angle and place between the
transformers protecting the third corner.
Hold in place with a pair of large cable ties or
doubled/trebled up smaller ones, preferably with delatchable
grips .

Hiya!

I have several sets of thingies I use. They're just a pair of 3/4" X
10" X 10" boards nailed together at right angles (think over-sized
bookends). They sit upright on the bench, making sort of a box shape
with an open end facing you.

Looking down from above:

(hope that comes out right; I could post pix...)

Once they're the right distance apart, the amp fits on\in the top.
Sometimes I get an amp with the trannies right at the edge of the
chassis, but I usually rig up something to accomodate. It's quite
stable and wicked simple. Since I like to work standing up, it puts
the amp at a better height, and allows ample room underneath.

HTH,
