[QUOTE="charles, post: 618912, member: 2759"] Dear afroaudio, I have never seen such a configuration on a TL12 plus. According to the book: Firsts in High Fidelity -The Products and History of H.J Leak & Co. Ltd. by Stephen Spicer: The output transformers: ID number 3921 (screen tap 49%) and ID 8778 (screen tap 25%). I looks like yours has a different number. The TL12 plus circuit diagram in the book indicates output taps for 4, 8 and 16 ohm. Your TL12 plus could be one that was configured for Broadcast or other applications. An example: There was also different Leak 12 point ones made for Broadcast, PA, Commercial and even Modulator use. Kind Regards Charles [/QUOTE]
