CCS Active loads and signal current control The use of active loads (CCS’s) in vacuum tube amplifiers has several advantages over resistive loads. These including full mu of the tube, lower distortion, and greatly improved power supply noise rejection.

Зазор в выходном трансформаторе (Партридж)

Зазор в выходном трансформаторе (Партридж) ЧАСТЬ II (OKOHЧAHИE). DR. ТОМ HODGSON Sound Practices № 10 Продолжаю свои заметки, начатые в S.P. № 5, о пионерских работах Партриджа по искажениям в выходных трансформаторах. Вкратце напомню смысл первой части: д-р Партридж в конце 30-х был захвачен идеей выходного трансформатора (ОТ-Output transformer) для РР (push-pull) с воздушным зазором. Этот зазор уменьшал индуктивность первички, оттого габариты сердечника были существенно больше. Трансформатор…

Pentode with a CCS

Pentode with a CCS Here are the results of some Pentode driver stage experiments done awhile back. The idea was to see what could be done combining Pentodes and CCS's. Generally, you can't load a Pentode with a CCS as you are effectively trying to series couple 2 CCS's. This issue is resolved by having a plate resistor in circuit so there is a defined resistance that the Pentode and CCS can work into.

DN2540 High Voltage Constant Current Source DN2540 High Voltage Constant Current Source Ever dreamed of getting the highest possible linearity out of your triode gain stage, by means of using an extremely high value of an anode resistor, say 1 Meg or more? If only that would be possible, we would have a nice, almost flat, load impedance line on our anode characteristics, and the resulting high linearity …
