F6 Turbo

[thor61]

Hello everyone, Any chance of a F6 Turbo deign in the work's ?

Add another pair of output devices, increase voltage, increase heatsink size, use ohms law to see if you need to change any of the resistors values for new voltage.

Add another pair of output devices...

Or two.

...increase voltage...

But, watch the dissipation and voltage limitations of the input JFETs. You may have to cascode them.

In the BA3 and F5turbo articles nelson states that up to 32v is safe for the input jets taking into consideration the dissipation of the device.

So with 28-32v operation one should be able to increase the power of the amp by a small margin without much modification of the circuit.

better safe than sorry

however - Pa can do that , having plenty Toshiba critters to choose from (using lowish Idss ones)

common Greedy Boy is not having that sort of commodity , so put cascodes for better sleep

Any thoughts on how to make it a balanced version like Pa has shown for the F5Tv3 and BA3 balanced FE?
