Valve Art KT100
Does anybody have some data or a datasheet on the Valve Art kT100?

It seems to be impossible to find...

Best regards,

It's an attempt market con.......really an upped 88 in thicker glass.....omo....a total waste of time whoever conceived using the standard octal base. I'm also after Tung-sol 6550 info......but again nothing I only purchase from vendors who are willing to give specs..

Thanks richj.

Market con?
I have heard it is closer to the kt90, with a special plated copper anode, higher transconductance and lower plate impedance than the kt88. But that may be wrong...

Maybe i`ll try the kt90 from EI or EH...

Thanks again,

EI KT90's....unfortunately rank not- on my opinion scale.....poorly made......with poor spot welds and internal shorts....maybe I got a poor batch..... rather embarassing when on live band shows. ....

Last year the KT90 has been discussed on this forum......I found with the standard UL 43% p-p circuits it produces roughly double the thd compared to a good KT88.

I haven't tried EH tubes there are so many different names made by one manufacturer....others on the forum have tried the KT90.....I believe with favorable results.
