I am planning on using the ECC99 at the 150vdv -4v 18mA operating point.
Looking for a good 1:1 IT to load it with.
I am probably going with the Lundahl stuff... but unsure which one?
Also, should I parallel the 2 sections of the ECC99 for 36mA?
finally, would a grid choke on the input make any difference?
Thanks for any help!

Hi Richard,
I assume you are planning this as a single ended IT so my experience is only of general use to you. I have LL1660S IT's which I use with 6n6p in PP. I think the 6n6p is similar to ECC99. The IT upgrade was a nice improvement for me changing from a cap coupled LTP. Seems more lifelike and realistic. The IT's seem to provide better drive to the output tubes and the amp seems more powerful.
