Some more interesting Submini Pentodes (data sheets included)

[frequencycentral]

I've been using 5672 a lot (as you know!), they're easy to get hold of and cheap. They are actually power amplifier pentodes, with a power output of 65mw.

Here's the results of some searching I've done for more power:

6999 - power amplifier pentodes with a power output of 135mw: http://frank.pocnet.net/sheets/138/6/6999.pdf

6397 - power amplifier pentodes with a power output of 140mw: http://frank.pocnet.net/sheets/020/6/6397.pdf

6526 - power amplifier pentodes with a power output of 375mw: http://frank.pocnet.net/sheets/138/6/6526.pdf

They all look interesting to me, though they seem harder to get hold of than 5672.
