Hello folks, I want to do some things with my heavily modified Princeton - its now a 6L6 amp - without a rectifier tube but a rectifier made up of some diodes on a tag board - it has no bias control - two pronger So what I want to do: - I want to add a bias control - three pronger - change caps - possibly change the two parallel caps in the power section(?) that seem to be .47uf (Orange drops) to .01 (but I am not sure what the tonal differences are with different values in this place - I once knew but have forgotten . . . anyone want to remind me?) So my questions: - where do I put a bias control - would that go between the Orange drops and the bias section and how would I wire it up . . . any ideas? - Three pronger: black goes to switch then fuse? or fuse then switch, and remove Death Cap? If I keep death cap in will it still be deadly? and wiill it serve some sort of line filtering? or is it best just to remove it? - How hard is it to put in a 'Standby Switch" perhaps in the 'Death Cap'- ground switch hole? Here are some pics of the inside: I note that it looks like the power section (if that's the area with the Orange Drops) feed directly to the power tube . . . is that where I would intervene with a bias pot?
