1) is generally the option Werner recommends, with a variable resistor in parallel with the primary of the autoformer. He indicates it is for "rolloff", presumably indicating that it is used for impedance compensation to control the rolloff frequency.I have another potential alternative: I have a Dennis Had SE KT-88 amp that can use anything from a 6V6 to a KT-150 to give 5-12wpc. I also have another amp on order from him, this one a parallel SE amp that will output 15wpc with KT-88's. Depending on tubes use and the amount of attenuation needed on the 802, I may be able to run the PSE amp on the 414 and the SE amp on the 802, with a 3-5 dB difference in power between the two.
