Hello. I am interested in using the EHX KT90 tube.
Does anyone know where I can get a copy of a data sheet with plate curves for the EHX KT90?
I have a copy of the Ei KT90 data sheet, but it would be nice to have plate curves for higher screen voltages, and for the actual EHX KT90.
I did find this:
http://www.pearl-hifi.com/06_Lit_Archive/01_Audio_Notes/Audio_Output_Trans.pdf
Which has plate curves for 300V screen.
Any ideas? Or, at the least, does anyone have some information on this tube, like how similar it is to Ei KT90?
Thank you.

Hello,
I hope those Spec Sheets I forwarded you helped you out.

I think that a web site page with tubes datasheet could be
very useful to people who wants to use your tubes in a custom/diy project…
F. Ex. I need the datasheet or specification of 5U4G rectifier tube, ex max current, voltage drop,
etc etcBest regards

I would like to request a datasheet for the EH KT-90. I have read someone’s claim that the screen grid construction is more robust than that of the original Ei KT-90. If you have any info on this, would be much appreciated.
Best Regards,
HT

Below is a picture of the power supply that feeds my audio deck. I’m running six KT-90s in push pull parallel, wired in triode mode with B+ at 525V. My Ik is around 65 mA. Any concerns?

May 15, 2010 at 1:24 am #102854Mr.GrimMemberyeah….when requesting for sum one to send you info to your email, i suggest you private message them your email, so not everyone can see/use it.
September 7, 2012 at 5:01 am #118122DannyJGloverParticipantDear Fuzz et al.,
Could I by chance get a hold of those EHX KT90 plate curves as well?
The complete datasheet would make me smile. -
