Thanks for all the responses.

I was thinking about the 5AR4 which does have one of the slowest power-up
times but wasn't sure if the different rec would affect the plate voltage of the
El34 output tubes. Will it? Thanks

Is there a drop in replacement for the 5V4 that has a slower voltage rise?
Thanks.

5AR4 / GZ34 should work as a drop-in replacement, with slightly lower
(about 5%) filament current requirement.

I don't have specs on warm-up characteristics available though, so don't
know if it would actually gain you anything.

Cheers,
Fred
