Connecting heaters on Princeton Reverb

[Amp'd Up]

Can someone verify if my thinking is correct...

I have a 6.3V supply for the heaters. On a 9 pin preamp tube...Do I jump pins 4-5 together and use pin 9? Join all 4-5s together and 9's together?

Is this correct?

Thanks.

Yup. Keeping them in phase. One leg to the 4/5s and the other leg to 9s.

Ok. Thanks! That's what I thought. Just need verification at times.
