Interstage transformer vs coupling capacitor
WebAnother common problem with vacuum tube amplifiers is the value chosen for the interstage coupling capacitors. In the case of the Dynaco St-70 for example (see attached schematic) coupling capacitors C10 and C11 are 0.1 uF. This introduces another large low frequency roll-off within the feedback loop. WebJun 25, 2010 · A relatively cheap capacitor may beat a relatively higher cost transformer, unless the last one is high quality (and expensive) Yes. If relatively cheap 9s not high …

WebOne uses a Lundahl interstage transformer while the other uses the more common capacitor coupling method. It’s possible to outfit the kit with a grid choke on the input tube, as an option, as well. The tube type used in this input stage is a class of high transconductance pentodes that are connected for operation as Class A triodes. WebApr 9, 2024 · Instead, the low input impedance of the bipolar unit demands a step-down ratio in 1transformer-coupled bipolar-transistor amplifiers. Figure 2.6 depicts the circuit of a two-stage FET amplifier holding transformer interstage coupling. At this point, transformer T1 delivers a 2:1 step-up, and it is quite a convenient BJT-type interstage transformer.
WebFig. 1. Examples of existing noise optimization techniques based on feedback through: (a) a transformer between the gate and source of a CG amplifier; (b) a transformer between the gate and source of the cascode transistor in a cascode LNA; (c) a capacitor between the gate and source of the CS transistor of a cascode LNA; and (d) a transformer … WebA 1:2 interstage by Tribute. ...
