Hello Romy,

Which other output tubes have you considered? I researched ‘suitable’ output tubes to drive tweets a while back for compression drivers [Be domes] — but not phenolic domes. Reading of your results with the EV tweet reminded me of how sweet they sound.

The tubes that made it to the top of my theoretical ‘A’ list were the 10Y, the 45, and the 46.

I have finished collecting the above NOS/UOS (and others) and will start breadboarding this fall, health permitting.

I hope to be able to do a bit of experimenting with some phenolic compression domes. For the first Frankensteinian co-combination, I’ll replace the Be dome on a TAD 2001 with a phenolic epoxied to the TAD surround VC. I have only one used old stock phenolic that can match — with some removal of the junction phenolic/VC surround — so I’ll start with a mono proof of concept first.

Did you mention a potential source for replacement or currently manufactured phenolic domes?

Paul B
