Re: Output transformer question
Hi, u should use the KT66 ideally, tho people do use EL34's. If u plan on using EL34's u could mismatch the speaker load to the impedance selector, ie; use an 8 ohm speaker load with the selector set to 16 ohms, this way the EL34's would see a plate to plate load impedance of 3k3. Hope this helps. Cheers
