No export, but use all (both) heaters.

Hi, The 5751 can be used on either 12 volts with the power applied to pins 4 and 5 (no connection to 9) or 6 volts if you tie pins 4 and 5 together and apply power between them and pin 9. The other tube is strictly 6 volts between Pins 4 and 5.

If you look at the schematics for the amp you will see that both triodes in the tube are used.

Good listening
Bruce

I drew up a turret board layout over the weekend. There will be some minor changes later on but I'm posting it for possible review as it is. It's similar to eshazen's layout in some ways. This is for a 3 1/8 inch hand drilled board. The tubes will be mounted to the chassis in a way where the 5751 drivers are furthest from the PT.
It is per the V2C schematic, 220k resistor is going to the 1K/1W resistor instead of ground which I've picked up as a mistake in the latest schematic.

Not bad for my first turret board layout? ;)
