Rogers Model 10 Chassis 21-6F7M tube

[Rick D]

Hello To All
I am waiting for some replacement tubes to arrive befor I power up my Rogers Mod.-10 chassis 21 radio, after I had
ordered the tubes I took a second look and checked the 6F7M tube spot ,the tube that is in the radio is a 6F7S tube with
an adopter that the 6F7S plugs into befor going into the chassis tube base,when I check this tube while in the adopter
it checks very low on the second test of my tube tester but if I take it out of the adopter it checks fine on both test,I was thinking
just take it out of the adopter and use it that way ,but the adopter has 8 pins the 6F7S has only 7 pins and won,t
fit in the tube base ,the tube base has 8 pin holes.I was going to order a new 6F7 tube but I am thinking it may have
only 7 pins like the 6F7S tube and I can,t seem to find where I might get another 6F7M tube,is there anyone else
that has had this problem and can anyone tell me where I might get a replacement tube,I also checked under the
chassis and I don,t see that anyone has changed any wires on the 6F7M tube base,I think the changes if any have
been made in the adopter.I sent a photo of the tube and the adopter,you can see the 6F7S tube has only 7 pins and
the adopter has 8,from what I have read the 6F7M tube has 8 pins,Thanks for any help ,all the very best Rick
