As there is the possibility to use the ECC83 as preamplifier (sent by my friend Andy) I want to clear a little doubt I have regarding this valve.

The ECC83 have the filament in two sections. In order to connect it in 6,3V:

Should I shortcircuit pins 4 and 5, and connect the 6,3V supply across pins 4-5 and 9?

Thanks.
