Cut out 4-1000 linear amplifier
By and large discussions of sample rate are like watching paint dry. Do we really have to get into the details? After all, everyone knows that you only need to sample at twice the frequency of your signal of interest to get good results, right? If you answered "right!

What You Really Need to Know About Sample Rate
This is a list of vacuum tubes or thermionic valves , and low-pressure gas-filled tubes , or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics. Many industrial, military or otherwise professional tubes were also produced. Only a few types are still used today, mainly in high-power, high-frequency applications. Receiving tubes have heaters or filaments intended for direct battery operation, parallel operation off a dedicated winding on a supply transformer, or series string operation on transformer-less sets. High-power RF power tubes are directly heated; the heater voltage must be much smaller than the signal voltage on the grid and is therefore in the In some valve part number series, the voltage class of the heater is given in the part number, and a similar valve might be available with several different heater voltage ratings.

Tetrodes are more difficult to use than triodes. This is due to additional supplies and safety interlocks. Small tetrodes are not at all interresting for economical and works necessary time reasons. A good point for tetrodes used in decametric bands amplifiers: A wideband grid 1 input circuit see later on this page is very efficient and simpler than a cathode driven triode with bands switched input circuits No major technical changes between this one and the old revisions they worked , except some layout arrangements, which removed mains AC voltage from logic board, easier wiring to front panel PCB LEDs and switches with flat ribbon cable and IDC instead of terminal screwed blocks.

QRZ Forums. I recently restarted the project and thought I'd ask for advice. First some facts: My 's I have four are probably at least 40 years old and were stored in an unheated building My HV transformer is producing volts to a full wave bridge to fourteen mfd, V caps in series with three 9K 7 watt resistors in series across each cap in the string. My is heating nicely with 7.
NA or SA? Subject : NA or SA? On MAY I'll summarize the rough neighborhood stuff later.
Sometimes you need a resistor with a value you don't have in your kit. Instead of ordering and wanting for a resistor with a value you need you can change the resistance of a resistor by using another resistor or many. By installing resistors in a parallel or series circuit you can change the value in Ohms. Here is a link to a resistor calculator.
The Navy decided to dump two old 10KW AM beacon transmitters into the ocean and replace them with modern units. I convinced the communications officer to allow me three days to pull parts off these transmitters before they dumped them and from these parts I built a A linear amplifier. I used that amplifier for nearly thirty years in various locations until the HV transformer shorted to ground and then I gave most of it to someone who really wanted a linear and had the parts and talent to replace the HV system. I am neither an engineer nor technically trained so my electronics knowledge is self-obtained and has lots of holes in it. I have a third with a steel plate and might do something with that later. A watt is a watt. Here is a.
