  1. Commento *Grazie per il sito ….ottimo . Vorrei dare il mio contributo facendo presente che lo schema del conductor steelphon nel finale con el84 è sbagliato… I catodi sono a massa e il bias è logicamente scollegato da questi, avendo una tensione negativa. Lo schema giusto ricalca esattamente il Polaris tranne che l’anodica dell’ecc81 che è come disegnata sul Conductor con una R19 e R20 da 470K che collega le 2 anodiche( EL84 e ECC81)

        • Commento *ciao Igor come ti avevo scritto ho acquistato un apollo 120 purtroppo martoriato e non funzionante. Il vecchio proprietario aveva fatto cambiare il trasformatore di alimentazione mettendone uno sbagliato e cambiando delle resistenze ecc ecc. Praticamente facendo una cagata pazzesca.
          Ora vorrei rimetterlo in sesto e il tecnico non trova lo schema.
          Mi servirebbe sapere le tensioni del trasformatore vorrei vedere la parte dell alimentazione e la tensione bias sulle finali.
          Per piacere ti chiedo di aiutarmi perché se no sarò costretto a buttarlo.

  37. Ciao, ho domande sullo Steelphone Conductor. Si dice che sia stato installato un ECC81. Se sì, è nell’ingresso o nello sfasamento. Ho installato 3x ECC83 qui. L’uscita ha 4 o 8 ohm? Quali sono le tensioni presenti in C16 – C20? C15 e C16 hanno ciascuno 1000uF e non dovrebbero avere più di 100 uF63 volt. Basta avere un piano senza informazioni su resistenza e capacità. Saluti Herbert dalla Germania.

    • cioa herbert, il driver monta ecc81, L’uscita è da 4-8-16, di solito si usa il verde a 8 ohm i condensatori di filtro sono tutti da 50 micro

  38. Ciao Daniele e’ passato un anno !! Hai trovato qualcosa a proposito di questo schema misterioso dell’APOLLO steelphon.
    Se si facci sapere. Comunque se hai una foto a COLORI del circuito stampato potrebbe aiutarmi a chiudere il cerchio e potrei addirittura ridisegnare lo schema elettrico

    ho visto la richiesta di aiuto di Massimo alla ricerca dello schema dell’Apollo Steelphon, forse potrei dargli delle dritte per rimettere in sesto l’ampli.
