WTB Wanted - type 27 mesh tubes

[andyjevans]

I'm after some interesting mesh type 27 tubes. I have a pair of rare ones which I love, but haven't found any like them. I don't want the common RCA types with the round asymmetrical mesh, I have those. More interested in the Philco types with flat square mesh, or any like those. PM me if you have any spare 27 mesh tubes please - I use them in my daily amp. I'm in London UK.

so I have 7 (possibly 8 depending on if you are interested in an unusual Ergon EY-227) with the "flat" mesh style rather than the cylindrical mesh structure attached on one side that is more commonly seen on RCA's

Cunningham C327, Tested on Hickok Tv-7d/u, 44/25 minimum
Ceco, Tested on Hickok Tv-7d/u, 37/25 minimum
Philco Type 27, Tested on Hickok Tv-7d/u, 35/25 minimum
Ergon EY-227, Tested on Hickok Tv-7d/u, 44/25 minimum

the ergon one is interesting, very heavy flashing, but interesting mesh structure inside though hard to get a great picture - the two pictures of individual tubes are that one. One shows flashing, one held up to list to see the structure. it does seem more cylindrical but rather different than the normal RCA cylinder

Hi Andy, I've got quite a few different mesh 27's. They're my collector valve, sad to say my family think I'm odd.
If you're interested I have some bond 27 with punched plates like the old 12 series of pre/power valves.
