Since it seems that no-one around here has any real impressions about the Tr-07hp, I've decided to jump the gun on one, and have just placed an order with Shikada San! Will be sure to share impressions once I get my hands on them

I have a question for tubes specialists:

 

I am looking for a pair of (matched if possible)  Western Electric WE417A driver tubes for my EC445 amp;

 

I found may be a pair, and I see that the vendor mention:   417A WE NOS (439=1954)  best single (Gm=25,000) strongest single tube

 

--> what does  Gm=25,000  mean  ? Is the highest the better ?   do those values need to be very close for the tubes to be considered as "matched" ? or is matched based on something else ? 

 

--> and I guess (439=1954)  mean "produced in 1954" ?

 

 

by the way, if someone can tell me where I can get those rare tubes.... ;)

A quick note to say that, after break-in, the TEN + Telefunken diamond base berlin df96 are.... exquise combo :p

I am very curious to see how this sounds. I saw that this is just coming out so will keep an eye in this. Also have my eye on the TUR-06. Big decisions to be made. If anyone gets there hands on the 07, please post. Trying to weigh if I want to dip my toes in the tube realm...
