idealmente : RD2 = 1093 ohm RC1 RC2 deben ser iguales entre entre {100 y 1k} ohm. Admiten una dispersion de 10%. RE = 1.5k, A RC iguales tiende a desequilibrar el circuito cuando aumenta en valor. Es preferible que RE sea menor en vez de mayor. A RC2 > RC1 : punto de reposo en 4.97 y siguie siendo mejor que RE sea mejor a que sea mayor A RC1 > RC2 : Punto de reposo en 5v! conviene mucho mas que RE sea mas chica
Eficiencia: 75.5 - 71.2 : En Re = 1.5k y par diferencial no darlington. Regulacion de linea es -2e-5. Regulacion de carga es 4e-5. Corriente por Re 0.65 mA.En este caso hay mayor RRMC que con RE= 1k. 75.5 - 71.2 : En Re = 1.0k y par diferencial no darlington. Regulacion de linea es -2e-5. Regulacion de carga es 4e-5. Corriente por Re \simeq 1mA. Ganancia de lazo 80dB. lazo cerrado es de 98dB 75.5 - 71.2 : En Re = 1.5K y par diferencial darlington. Regulacion de linea es de 9e-5. Regulacion de carga es 0.0002. Corriente por Re \simeq 0.4mA 75.4 - 71.4 : En Re = 500 y par diferencial darlington. Regulacion de linea es 2.75e-5. Regulacion de carga es 9.95e-5. Corriente por Re \simeq 1mA

Questions
What parts does the TP Integrador use?
39 parts, built around the TL431D, BC547C, BC557C and 2SB631. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TP Integrador KiCad files?
From the Amalia-O/TDCE repository on GitHub, at the commit this page was made from: the board is PCB/TP Integrador.kicad_pcb and its schematic PCB/TP Integrador.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TP Integrador design in my own project?
Its repository states no licence, so its author keeps all rights: ask Amalia-O before reusing the design.
