Pretty hard to find a long plate that works in high-gainers, though, because of the microphincs.
I don't doubt some tubes can handle it. But statistically, you have to buy more to find the right one.
The JJ ECC803S could sound nice in V1, but I think the Sovtek LPS is way too tubby-sounding for that position. Haven't tried anything NOS, TBH. But not really interested either, especially considering you'd still have buy a bunch to find the right one in the microphonics department.
