Plate dissapation is a power limit for the piece of metal making up the plate...Put DC on the Tube (no RF), make it heat up and measure the power versus temp curves and decide what the limit should b
Pavel's an ok dealer. But, the whole banking system in Russia and money transfer mechanism is costly and difficult. Suggest buying two at once and combining the money transfer costs.
If you're lucky it just the HV rectifier diodes. Disconnect them from the transformer and see if it still blows. Another possibility...the electrolytics either are shorted or need reforming. If pulli
I think the smaller cones stiffen the of the overall speaker cone to ensure the whole cone moves as one when fed with high power because it has to move close to an inch at 100 Hz. contact)
Here's link for a shunt regulator approach to active noise cancelation applied to low voltage power supplies. http://www.wenzel.com/documents/finesse.html Fundamentally there's no lower limit to the
Flux density rate of change is related to Voltage V = dB/dt and V = L di/dt So dB/dt = L di/dt Integrating both sides B proportional to I you saturating apply voltage is at resistance
It's possible to generate a 1.5x multiplier with a nonlinear C or L. I once designed a 144 to 226 multplier with a varactor diode and some tuned circuits. The circuit contained an idler tuned circuit
generated sub without I noise, produces analysis tests Ahh. That's the best explanation I've heard for what causes sub-harmonics. Thank you. Now where's the nonlinearity in the solid state PA's? from
Here's two web pages that discusses using variable capacitance to produce gain at f/2 as part of a larger discussion of varactor diodes and parametric amplifiers.. These pages specifically discusses
The reference to gain at f/2 is there...near the top of the second reference... For proper operation, the capacitance must be decreased when the input voltage is maximum and increased when the input
Comments embedded below... And yes, this is a very interesting topic. Of course the real problem will probably turn out completely unrelated. on his sub-harmonic re-inforcing I still think something
You're quite correct that non-linearities do not directly generate anything other than integer harmonics 2f, 3f, etc. But it still possible to generate sub-harmonics with a non-linear reactance, a pa
Quiet? Not the FCC Class B telecom units I've been playing with. These beasts put out relatively low noise differentially between output V and its ground but put out a lot of noise "common mode" betw
The meter almost certainly uses an external shunt...so it really isn't a 5 amp meter. If you look closely you might see "100 uA fs" or some such on the scale in fine print. Alternatively, measure its
Three points, I think Generate the heat very close to the tip...with very little thermal resistance between heat source and tip. Temperature regulation, power proportional to load Very little therma
I just did that here. I put line voltage across the HV side (measured 115V) on the HV side and measured the line side output, it was about 4.25 volts. That gave me the turns ratio (about 27:1) and so
