If I have understood this correctly, then from the transformers of the two amplifiers shown in the two pictures below (when zoomimg in, their transformers look pretty similar on my screen to the ones in the Dumbleland Special 150W #009 ?), one can conclude that the output stages of this Steel String Singer 150W and this Overdrive Special 150W also have such an ultralinear circuit? Or have I misunderstood that?talbany wrote: ↑Wed Apr 14, 2021 9:08 am ... The Dumbleland's Output transformer is equipped with ultra linear taps, this enables you to run the output tubes at higher plate voltages for increased power output, given that the screens of 6550 are not designed to handle these higher voltages under load ...
