Interstage for a 10 /10y/801/801a tube

Welcome! Need support, you got it. Or share youe ideas and experiences.

Kevin,
The LL1660 has been recommended to me by Thomas Mayer for use as an interstage to couple the 10 tube as a driver to an output tube.
The LL1660 is normally gapped for 18ma. He says to use the LL1660 that is gapped for 25ma. (1+1+1+1:2.25+2.25). I look at the specs and it shows at connection Alt S. , freq resp to be 25-40KHz, 14k source impedance (1:1.125)
The Lundahl specsheet shows LL 1671 /30 ma as the high current version of LL1660.(1+1+1+1:2+2). Can I use this instead? Specsheet show at connection Alt S, freq resp is 30-30khz but only at 3k source impedance?
I ask coz i already have the LL1671 in my parts bin and wanted to use it if at all appropriate.
