Nope. The 2N3055 has a practical Hfe (gain) of 10-15 in this application, so to supply the base with nearly 1 amp *through* a carbon wiper pot is insanely unreliable.
The potentiometer will burn out at a load current of several amperes. Here, a Darlington circuit should be used, with an additional, smaller transistor at the input, or simply use a single Darlington transistor instead of 2N3055.

si?, no te diste cuenta que la entrada de tension la conecto al colector y la salida al emisor?, eso asi no funciona, o ahora vamos a reformar los componentes electronicos en un videito?.

Zéro à 60 v, 15 À, really ?! I believe that the author uses to forget a lot of "details"! Ex: output:5v, current :15A =75w to the output.. But 60v -5 =55v, with 15A,who are dissipated by the transistor 2n3055, so 825W!! Sure that the transistor cannot dissipate 825 W, even with its big heat sink !! Theses performs are true, when it observes the dissipation hyperbole of the transistor, and have not to exceed power max of it.

Muy buen y sencillo diseño, pero para fines educativos ya que para ser usado como fuente de laboratorio, así sea para un principiante tiene un par de defectos, Los 15 A. son el limite de corriente del semiconductor, o sea se lo haria trabajar al limite, no recondable, Ud. lo presenta como una fuente de 0 a 60 V. ahí va a tener un inconveniente serio, el limite de tension segun el fabricante del 2N3055 es de 50 V. alli tiene un problema serio, y Ud. no aclara en nigun momento que se trate de un equipo experimental o educativo, entonces se deduce que es una herramienta para laboratorio, Yo le recomendaria modificar los conductores del Colector y el Emisor y las pistas relacionadas, porque en cuanto comiencen a circular una corriente 15 amper por ellos, la resistividad propia de los conductores van a comenzar a generar perdidas termicas -calor- propio de la subdimension y aparejado no va a entregar los 60 volts ni de casualidad, amen de el riesgo quer los conductores y las pistas relacionadas se fundan, poco serio lo suyo amigo

Merhaba ben de katılıyorum ilk fevremiz bu idi 3055 sürmek için bd135 kullanılırdı o zaman bile potansiyometre den kıvılcımlar çıkardı
You don't believe the pot can handle 60W? 😂
Output voltage 2V ;current :15A. The 3055 has to dissipate 58x15 = 870W...

Use the 2N3773 or the MJ15003 to support the voltages you suggested. The power rating of the potentiometer may need to be increased.
