Hey all, I am building a low watt amp that will take features from the Mojotone Studio One. Both preamp channels will pretty much be built as Mojotone had laid it out. I will remove the channel switching relay and have the channels mix with a pair of 220k resistors feeding the output section. However I have a pair of 12BH7's that I would like to use, so there will be a little more output from the cathode biased output section. The question I have is when adding a second 12BH7, do I still send the B side of the triode grids to ground on both of them when they run in parallel? It begs a 2nd question as well....when adding the second 12bh7, does the reflected impedance go down? Therefore running an 8 ohm load off of the 16 ohm secondary? I have attached Mojo's Schem for the studio one.
