Default EL84 in ultra-linear mode

Does anyone have IV curves for the EL84 in ultra-linear mode (standard 43% taps) ?

I have only been able to find curves for pentode and triode mode.

Whew!

That should satisfy you, CS! I have set the printer churning, since much of this that I had years ago went the way of al - er - books. My thanks to Giaime and Edl also.

Just an extra small point; I have a single graph illustrating that optimal conditions for fixed and cathode bias are not the same for minimum distortion; different load impedance as well as bias. Unfortunately I am not at home at present, and will only be able to post this by end of week. I have not studied the above data; it might be that you can work that out from these two sources.

Regards

Hi Ray_Moth, Giaime,

Thanks for concern. Physically almost OK, but still staying with my son. Will have to move back to my home shortly; psychological issues will have to be dealt with. Reading and contributing to this site help considerably in that respect!

Regards

Ray_Moth,

Sorry man, never replied. My injuries (broken ribs) have healed well and otherwise everybody (including my son where I still stay) are looking after me admirably.

The trauma of a lost spouse will be there forever, but life must go on. Taking part here is also a definite cure.

Thanks.
