Who Sells 6GM5------->7591 Adapters?

Who Sells 6GM5------->7591 Adapters?
AES (Tubes & More) doesn't list them on their web page anymore. Does anyone know where I may buy some?

They're called "soldering irons".
Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

Heh, heh,  
R.G.'s comments were a tad more terse than what I was thinking but essentially the same. A couple of quick tricks -you can get dead/useless metal octal tubes with the appropriate pins in the base and remove the base by unsoldering the pins and uncrimping the shell. Then break out the internal tube and grind off enough of the top of the shell to accomodate a 9-pin socket. The rest is just wiring old octal pin to socket pin appropriately and then crimping the base in and epoxying/soldering the socket in the top. To prevent future confusion make sure the label the device "6GM5 to 7591" adapter.  
A second, uglier way, is to again get and clean up an appropriate octal base - not a wafer but a full depth one - and then carve a wooden, phenolic, or plastic "stick" that will insert into the octal base location pin from the back and glue it in there. You can then put a flat headed wood screw through the middle hole in a 9-pin socket to secure the socket to the base. Again, wire up appropriately - test - and then fill with silicon glue. I've made these adapters and then covered the outside with copper or brass foil to sheild the connections but they are "uglier than home made sin." With some craft the metal octal ones can be made to look quite nice and can even be painted various colors with enamel. Octal to octal adapters can be put inside 1.5" PVC Schedule 40 pipe with a little carving or the same size copper pipe if you can easily find it.  
PS: You can also make bias test adapters - octal to octal with built in 1 ohm cathode resistors and test tip jacks using the last method as well as general "break out" adapters.
