Svetlana's 6D22S TV damper diodes seem pretty good. They tolerate up to 600v heater-cathode, making them versatile. These are in current production.

The only downsides are that they are single diodes, they use a top cap for the cathode and they use the 9-pin magnoval socket, which is octal-size but can be hard to find.
