Does anyone have specs handy for 6CA7's? My vintage Marconi tube specs

Here's a good source for ALL tube types.

The 6CA7 has nearly the same specs as an EL34, but technically there are
some construction differences (beam tetrode vs true pentode). Often
they're double-branded 6CA7/EL34 which suggests they're a drop-in
replacement, but a purist would think otherwise.

OK. The EL34 specs are a big help, show AB1 P/P with 450 plate v.

Generally, set them to no more than 70% of Max dissipation.
