pdfbytes) Bold designators are close or identical, Italic designators are different ratings, different pinouts or different filament voltages. Please see the substitutes at the top of the page for more details. The 4- 400A is " rated" 10W grid dissipation per tube, but a similar triode in GG operation ( like a 3- 500Z) normally develops Ig of about 1/ 4 the plate current, so I' d think for two tubes the max Ig is around 200mA.
