[QUOTE="charles, post: 573636, member: 2759"] Another interesting piece of information; Apparently the ST 20 with the 3921 OPT transformer has a different circuit diagram as the one with the 8778 OPT. Observed it from the Internet. I have some original ST 20 manuals. Will check if I can check the differences. [/QUOTE]
