Sorry about the huge picture but now I can see those are 56's not 27's.

Be careful with flea bay sellers of 27's and 56's. I have been burned. :-)

I have found no sonic difference between brands of ST 27's. They are all good...if accurately represented by the seller.

Nice yes, but just to be clear, I don't have those globe tubes.

I had a pair of globe mesh plate 27's and they sounded very soft. Anyone have a positive experience?

I've been running globe 27 mesh plates and 56 globes as well. I like them both depending on the speakers I'm using. Both can be microphonic if you're not careful with placement.

I 'spose I just had a bad pair of mesh plates.

I ordered a pair of Cunningham 27 globe mesh for $22/pr today. Pretty cheap so thought I'd try them. Also found an interesting article titled Are Globe Tubes Better? on a site called VinylSavor: "It has been speculated that the absence of the mica in the globe tubes might contribute to their sound." The author thinks they sound better for his tastes in his amps due to there being "nothing but metal and glass in the globe tube. A big mica disc in the ST."

Let us know how they work out. I missed what looked to be a nice pair on the auction site.

Anyone listened to this? A quad parallel SE 6v6 monoblock amp, hand built by Dennis Had. 25 watts.
