They are GZ37's. GZ33's are a tad shorter in length. (I've seen enough of them to distinguish between the two. The proportions look like those of a GZ37.) Although the internal plates are quite similar.The funny thing is the Mullard GZ37 (and GZ33) is *already* a premium tube- I think it would garner a higher price had it been sold as a GZ37. I do think the B+ is a little higher than a U52 or 5U4, so whoever wins this auction better be using it in a circuit that doesn't run anything at max B+ with a U52 or 5U4. (The GZ37 is an indirect-heated rectifier, where the 5U4 is a direct-heated rectifier.)
I've seen a plethora of 5AR4/GZ34's being sold as GZ37's on eBay as well...
