In gathering the parts for this I have
1) and accutronics type 4 pan 4AB3C1B (8R input)
2) an SE OT 8k primary, 4R, 8R and 16R secondaries
3) a 6G15 (or a Hoffman/Weber/TorreT type 'revibe' - could go either way on this at the mo but it doesn't matter for the purpose of this question - I'm just getting sidetracked ;-0)
4) 6V6 driver - which is typically a 5W tube
I note that the Torre T revibe schematic lists an OT with a 5k5 primary and 8R secondary (impedance ratio of 687.5:1) driving either a 9AB3C1B pan or a 4AB3C1B pan, from either a 6V6 or a 6K6. That type 9 pan has a 10R input impedance, so I figure you would get a reflected load on the 6V6 of about 6k9. Whereas using a type 4 pan you would get your 5k5 reflected load.
If I use an OT with an 8K primary, that means that the 6V6 can be set up to run slightly hotter than it it would be if it was pushing a 5k5 or 6k9 load doesn't it? So how do I need to set the 6V6 up so that it delivers right amount of output power to the type 4 pan I have? (I'm not advanced enough yet to be able to sit down and work all this out on my own and I'd like some help please )
