Carefully opening a electroharmonics 6V6GT radiotron for a Fender amp While explaning in Dutch, Dave is carefully opening a popular 6V6GT electronic valve, using some traditional tools. While the inner workings get unraveled, the tube turns out to be interesting as well as beautiful on the inside too! The datasheet:

Marconi B6034 MF Transmitters final shut-down at Brookmans Park Transmitting Station. Following 31 years service, the last of the Brookmans Park Marconi B6034 50kW MF broadcast transmitters are closed down for the start of re-engineering to Nautel NX100s. They had produced a total of 240000 hours of reliable operation and this type of transmitter is still in service at other stations, including the similar 28kW B6046 LF version. The B6034 is an Impedance Modulated transmitter with AMC using 2 of 4CX1500B tetrode valves in cathode follower mode (audio) and 2 of 4CX35000C tetrodes for the final RFs.

Cold-Cathode Thyratron Cold-Cathode ThyratronYou have definitely heard about such a device as thyratron... Let's try to understand what it is.Thyratron is a gas-discharge rectifier with one or more supplementary electrode grids. The beginning of a current flow through the thyratron is regulated by potentials applied to these grids. Thyratron is a kind of highly sensitive relays that can be switched on (lit), but can not be turned off without de-energizing the anode.There are two basic types of thyratrons: cold-cathode and glow-cathode ones. We'll dwell on cold-cathode sign features, technical parameters and specifications determine the following advantages of cold-cathode thyratrons: high efficiency, simplicity of design, small size and weight, ability to conduct high currents in pulsed mode, relative stability of characteristics, durability, high vibration resistance, wide operating temperature range and low starting currents at high input resistance.We'd like to specify a few features of these devices:The role of the control grid of a thyratron differs significantly from its role in a usual three-electrode tube. In the triode grid the value of the anode current can be changed by voltage at any point of time, and in the thyratron the grid voltage can be controlled only at the moment of discharge ignition. After the moment of discharge ignition the grid loses control action, and current passes through the device as if there was no gridIgnition control in a cold-cathode thyratron ...
My old re-made Geiger Counter IBG-58-T, Irradiation testing! A revamped Czechoslovak IBG 58 T using my own GM tube and detector circuit (two NPNs as Darlington transistors, piezospeaker and LED diode added, driven through a 9V battery). Sorry for the hole at the bottom of the case... :-) Radiation exposures: cosmic rays, cold-cathode DY87 vacuum tube in reverse with 30kV on the input and heated Soviet 6VS-1 beam tetrode.

6P3S Radio Valve 6P3S Radio Valve In the Soviet times some goods, especially electronic components, were in extreme deficiency for some unexplainable reasons. This resulted in the appearance of the so-called legendary components. With their help some enthusiasts were able to assemble designs which were not supposed to have these components on them. A vivid example of such component is radio valve 6P3S. 6P3S is an output beam tetrode with an indirectly heated oxide cathode. Its heating voltage is 6.3 V. The maximum anode voltage is 400 V. The maximum power dissipated on the anode is 20.5 W. Amplification coefficient is 13.5. Transconductance is 6 mA/V.The valve works in any position. It has a glass design of cylindrical or figured shape. Lifespan is at least 500 hours. It has a 6-pin octal base with the alignment pin. It weighs no more than 70 g. The valve was used for amplifying low-frequency power. It was used in single-cycle and push-pull output stages of receivers and low-frequency amplifiers. The valve was also used as a high-frequency generator in tape recorders, transmitting devices, and other equipment. Its foreign ***og designs are 6L6, 6CN5, and EL34. This valve became legendary because unlike other valves it was sold almost everywhere. But the most important thing was that you could assemble quite a powerful short-wave radio transmitter from this valve. This was actively used by radio pirates. The history of the valve is also worth mentioning. Our legendary 6P3S went through ...

Valve amplifiers at anode current decreasing: Principle of operation In vacuum-tube amplifiers I created, I used the usual high-voltage lamps with anode low voltage. However, after the anode current was reduced, the slope of the tube characteristics changed, and its amplification dropped. But there are ways of feeding tubes with low anode voltage, which worsen their parameters to a lesser degree. For a tetrode or a pentode to operate at low anode voltage, you should do the following.
EMI 319 13 x 8 loudspeaker speaker movie The EMI 319 is not to be ill-judged from this up-close demo as cone tweeters have narrow dispersion of sound, whizzers are worst yet with top end said to be 'as narrow as a pencil' in the highest range. So back then folks with whizzers satisfied themselves the high end was there at a certain listening position, speakers toed in, then just didn't bother with it too much. Such EMI speakers need heard in good listening rooms to experience the depth of sonic picture they describe. But their corny appearance may take some getting used to, like the music of their day! A look at Lowther harman/kardon drivers in the link below show aluminum and bits of foam on the cones reminiscent of 1960s EMI. 319 are not disco speakers, but about creating 'the closest approach to the original recorded sound' - more than a 'Live' feel and better than Home Theater, albeit with very limited treble dispersion, EMI 319 give extreme realism in a tiny critical listening area, outside of which the speakers may sound more like consoles, being limited in their HF frequency response. Peter Walker hinted at this by talking about 'a window on the performance', his own QUAD ESL-57 suffered the same tiny window of hi-End quality where the EMI 319 bass is of the deepest, most lifelike possible! You need an amplifier like the harman/kardon A 402 already warmed up, to get these effects and an A 402 needs refurbished, as the solder gets very dry. But it has the 'stiff power supply' needed for QUAD ESL-57 ...

2 Valve Superhet using car valves and Altoids tins Using a 12FX8 and a 12AL8 12V HT car valve, a ferrite rod aerial, two Altoid tins and a block of wood I constructed a reasonable MW superhet with loud and reasonable audio. I spent more time aligning and fiddling with it to get it to work than I did in constructing it - be warned if you too want to make a simple superhet! The 12FX8 is a Heptode-triode and the 12AL8 is a triode-power tetrode. Both were developed for car radios and use the 12V car battery voltage directly for the HT. Using these two valves allows you to make a similar set to a five-valver (IF oscillator, mixer, IF amp, first audio and final audio). I used a silicon diode for the detector. Go to /on4nic/12V-2Valve-MW-Superhet for the circuit diagram and some photographs. Most of the parts came from radio rallies and eBay. Next version will be for an amateur radio band and will include a BFO for CW and SSB.
