Reading 38-116 Tube Pin Voltages with Tubes Horizontal
#2

Not a good idea especially for power tubes and rectifiers. Supposedly you can negate the possibility of a short caused by sag by positioning the tube (rectifier) just right, unfortunately they did not build the chassis with this consideration. Short term - maybe. Long term - No.

Upside down should be OK.

P.S. Old Suckers might have trouble reading your posts - increase your font size.
