 To the best of my knowledge, EI did not manufacture a short version of this tube. But short versions were manufactured by other companies, including Siemens. I tried the short Siemens and didn't like it. On the other hand, tall versions by GE, Mullard, EI and Sylvania have been favorably reviewed in the main Little Dot tube rolling forum. And yes, the proper LD setting for the 6HM5 is EF95.
 This is great price. But unfortunately, my old house is a bit of a money pit, so I am going to have to wait until I win the lottery (or find a sugar momma? lol).
 It sounds like a wonderful amp. If I ever win the lottery, I will buy one from you. :)
 Do you have original GEL3N with the side-contact base AZ4 rectifier? Or did Glenn swap in an octal socket?
 I paid $16.55 for a bunch of four 6BX7s so pretty cheap. :) Someday, I am going to have to buy an EL3N adapter, but for now, I am having too much fun rolling rectifiers. :)
 Yes. Oskari found this link: http://www.geocities.jp/radiomann/HomePageVT/TV_Ver_Triode.html#6BX7 And I found another Toshiba on eBay: http://www.ebay.com/itm/162214395149 Since the one I have looks just like these, same plates, micas, heat radiators and getter, I am pretty sure my Tunsgram was manufactured by Toshiba.
 I use 6BX7 as output tubes and therefore I need four of them. As I have only the one, will have to wait until I can find at least three more before I can comment on the sound. :)
 After a little more research, I now believe that this tube was manufactured by Toshiba. :)
 Bingo! :) Last night I found a Toshiba on eBay: http://www.ebay.com/itm/162214395149 And yes, the plates, micas, getter and heat-radiators are identical. But it is interesting that the Tunsgram tube does not have the octagon containing 6BX7GT and "Toshiba" etched into the glass. Anyway, $36.99 is a bit more than I am willing to pay, so will wait for a better deal.
 I bought it from a vendor in Italy. The decal on the base reads Orgal Radio and it appears that this company manufactured radios in Milan, Italy. http://www.radiomuseum.org/dsp_hersteller_detail.cfm?company_id=8139
