Howdy folks, need some help wiring a 5703wb Raytheon tube in one of my D49’s.
I have the datasheet denoting the lead next to the red dot but its numbered: 1(red dot) 3_4_5_6

help me please :D

From the old Tung-Sol tube manual for the 5703...

Lead 1  (red dot on envelope adjacent to Lead 1):  Plate
Lead 2:  no connection; gap between leads 1 and 3
Lead 3:  Heater
Lead 4:  Heater
Lead 5:  Grid
Lead 6:  Cathode

Ef 6.3 v 200 ma

Acrylic plate or a bottom you design with Frontpanel express.
Mdf will work. So yes, you have to do it on your own 😉
