At its rated maximum plate voltage of 3000 volts it A beam tetrode sometimes called a quot beam power tube quot is a type of tetrode vacuum tube or 39 valve 39 with auxiliary beam focusing plates designed to augment power handling capability and help reduce unwanted emission effects. RCA published an annotated diagram of the main components of the 813. The accelerator was housed in the McLennan Physics building and operated from 1982 to 2013. To suggest a video send email to Submissions to EHX. 3v heater filament and can dissipate 30W. Because of the unique internal geometry of the Svetlana 4CX400A the tube will operate at low plate voltage with high efficiency. beam power tube Explanation of beam tetrode. This is usually undesirable although it can be exploited as in the dynatron oscillator. The KT77 is also suitable for use as a series valve in a stabilised pov r supply. You can find 6L6G but not 6L6 G It is shown that the ion beam is forced to move from the anode toward the virtual cathode in a reflex tetrode which is made on the basis of a new idea that the plasma source is separated from the anode. 28 oct. If my memory is correct one normally ties the unused screen and suppressor grids to the plate. Can be used in terminal stages of low frequency power. Now back to the 6P21S tetrode curves this is the way I wired the valve before submitting it to the mercy of the uTracer. Electro Harmonix 6CA7 is a big bottle beam tetrode that 39 s drop in compatible with EL34. Can replace KT88s or 6550s. 6. The 6L6 is an 8 pin quot octal quot beam power tetrode tube found in the power amp section of many guitar amps mostly in sets of two or four matched valves.

The Penta 4CX250B M is a forced air cooled 250 watt plate dissipation external anode ceramic and metal radial beam tetrode. 6550 tetrode. The expressions are derived for the ion beam current densities which are extracted from reflex tetrodes. 1970s years. Brimar KT66 Beam Tetrode Data. 0 products in your cart total amount 0. The screen grid acts as an electrostatic shield to protect the control grid from the influence of the plate when its potential changes. This valve most probably would have been used as a series regulator in a power supply. E. The three pole array therefore acts as the feedback element stabilizing the operating point of the tetrode. Svetlana plantsThe price is for one tube. Of course a tetrode or pentode could also be used for this at the expense of great complication. A simple trigger circuit allows the generation of a burst of e beam pulses with variable pulse duration and pulse separation. 5 Oc 6F2 Beam Tetrode Audio amp RF Power Amplifier Gec73 Equiv. E. An alternative was to connect the screen grid to the control grid and use the device in a push pull amplifier a configuration known as 39 Class B zero bias 39 . Second harmonic distortion is automatically cancelled in a push pull design. It is likely that the valve was removed from MUDPAC and placed in the box that its replacement came in. The sound was far better to my ears than when I used JJ 7591S in the same amplifiers. For years beam tetrode tubes like the 6V6 and 6L6 have been widely used for guitar amps for their punchy drive and fast transient.

Beam tetrode som dukkede op senere og som anvendes til audio eller radiofrekvens effektforst rkning. General characteristics Name 6P21S Type beam tetrode Application HF oscillation and power amplification Well if you look at the plate curves for pentode beam tetrode operation you see that plate current is pretty much a function of screen voltage and that 39 s why most amplification stages that employ these devices also regulate the screen supply. Member 06 02 2011 06 38 AM. marked KT88. These tetrodes only have connections for four electrodes but they include a pair of beam forming plates that direct the electron flows. Although the pentode has replaced the tetrode in most vacuum tube functions a specially designed tetrode called the beam power tube has found extensive use in power amplification. In modern day schematics starting in the 1950s no distinction is made between a beam forming electrode and a suppressor grid.
