Thanks. The phase thing appears not to be any trouble. It works perfectly...ViperDoc wrote: ↑Wed 02/02/22 12:25 amI'm no expert, and this may not be an issue, but your DP3T wiring changes the phase of the HT pair throughout the series. It's simple enough to wire them in a linear arrangement to enable a low-middle-high voltage design that retains the phase as below:
I'm interested in the brain trust's opinion. Looks like a cool option, especially the maintenance of full voltage on the preamp.
I don't think the double rectifier will be an option.. I have a bad feeling about that.
Anyway, I don't mind not having tremolo at 2W switching... and the amp sounds great with this attenuation anyway, so for me it's not necessary to only scale down the power amp.
But it got me thinking... when you use a normal 18W power transformer 290V-CT-290V.. you can apply the same logic and use the CT and one HT terminal to attenuate the amp at B+ level
One would have to use a FWB rectifier tho...
