Default PX25 to 300B pins

Making a PX25 to 300B adapter from parts I got from Ebay. Basically a PX25 socket into a 300Bcup with pins at the bottom.

Can someone confirm that the anode and the grid aren't reversed?

Thanks!

By direct examination of a WE 300B I can confirm that the connections are correct as pictured looking at he base bottom. I have no experience with the PX25.

Thank you, the PX25 is less of a question because of its pin out, just wanted to confirm 300B pins.

Just would like to keep these fancy 4 pins teflon sockets on the amp, and make an adapter instead. Want to be able to switch between the 300Bs and some ancient PX4s - and don't want to install combo sockets.
