I just got a big box of some NOS Raytheon 5072 subminiature pentodes from ebay, NIB and all. These seem pretty robust and highly variable in their usage. The datasheets show info on nirmal pentode usage, as well as triode strapping. They are capable of 1.2W max Plate dissipation, but seem that they would be nice as gain stages (either configuration) in a boost design (ie pentaboost, valvecaster).

Here's the datasheet. http://frank.pocnet.net/sheets/138/5/5702WB.pdf

Anybody ever used these? Any experiences?
Gear: Epi Les Paul (archtop) w/ 490R in the neck, and SD '59N in the bridge; Silvertone 1484 w/ a WGS G15C

Still a tubey noobie. Been doing this a while, and still can't figure much out, smh.
