Hello – I have a Sylvania Gold Brand 5931 5U4G 5U4 JAN Mil-spec Rectifier tube for sale.

The 5931 is a premium 5U4 rectifier tube made for the military.

It has smooth black plates, a top side "D" getter and was made in the 1961.

This tube is NOS and new in the box.

I have two of these if you need a pair.

This has been tested in the power supply of my DIY pre-amp and is dead quiet.
