Its a russian Svetlana EL509 tube = extraordinary strong. It won´t break. It´s build for it cause its made in Russia for extreme conditions. But thanks anyway.. !
EL 509 you can only work with a froozer. Also our moderator had to learning read. The power is 240 Watt Watts. This Zetagi with original Equipment brings a SSB Peak (USB) 450 Watts. But you had to make a bunker for that, it wasd totally overdriven when you work on 27 Mhz. On 28 Mhz you will go with 300 W SSB and 20 W Input.
when talking on that you could make a grilled cheese sandwich to snack on. Got RM ITALY with a bunch of EL519 tubes. 240V flickers the lights in my room lots of heat. 900 PEP SSB
I don't like it, when a tube runs that hot. It's not a well designed lineair amplifier for sure. The plastic front melts over time, and the transformer is way to close to the tube.
is there someone here who has a wiring diagram from this bv 131,can t find it on internet only the ones without hi\lo switch...i need the one with hi |lo switch like this one...mine has a burned resistor next to the coil..
poor tube, a tube for HSync used in TV you get clean 30-40w, but 100w is totally overdriven. whatever, there are still peoples getting "1.2KW" amps with such crappy tubes.
your not supposed to cherry the plates like a 3-500 This is stupidity Your gonna warp the plate and probably short it out and defiantly reduce the life of it. en.wikipedia.org/wiki/Glowing_plate
Poor TV tube designed to dissipate an anode power of 30W maximum !!!!! Use real broadcast tubes not TV tubes !!! You destroy them by using them in these QRM generators that are those filthy amps made in Italy!
