WebSep 1, 2024 · To put it as briefly and concisely as possible: push a simple transistor circuit hard, and it clips (distorts) in a sudden, harsh, "square wave" way; push a tube into clipping and it distorts more gradually and more smoothly—it "rounds off" into distortion—and slathers on a gorgeous gravy of harmonics along the way. Webdrill tow hole just a little bit smaller than the fittings (the vacuum gauge came with a bunch of extra fittings) heat up the fitings with a soldering iroen and scre them in. when they …
WebWhat could make it more efficient is if the sample is stirred or slightly vortexed to increase the surface of gas exchange. Also cooling the sample is highly important! I wouldn't use sonication if... WebDuring electronic bombardment degas, as much as 500 volts may be applied to some electrode pins. Do not touch any gauge tube electrodes while the tube is connected to the controller. All Connections to the gauge tube pins should be covered by insulation. All gauge tube pins should be covered by connectors or by pin covers.
WebRemember that the sample mass initially placed in the sample tube will be reduced as a result of the removal of trapped moisture (degassing). It is usually a good idea to use 5 - 20% excess sample mass than required so a sufficient … WebReconditioning of a tube, SM6EYH style 1. Apply the heater voltage, but no other voltages. You will probably have to start the fan to avoid overheating. Leave the tube with heater only for 1 hour. 2. Connect the anode through a 50 to 100 kiloohm resistor. Leave the tube with the plate voltage through this resistor for 2 hours.
WebPower tubes are electrically matched so each tube will have the same amount of “idle” plate current and amplification characteristics when used in an amplifier. This is done so the tubes can work together in your amp giving you optimal sound quality and tube longevity.
WebMar 15, 2024 · The input is feeding the cathodes of the four tubes in parallel directly, with no impedance-matching network. This will result in a high SWR between the radio and amplifier when it is keyed and amplifying. The original article's date of 1968 is a clue.
