A 1956 Tung-Sol 5687WA arrived today. I put it into my test amp and as Xcalibur255 observed, it is quite liquid and fluid, with no grain, and the mid-range is rather forward and lush. To my ears, through HD700's, it sounds very good. A keeper. :)

I fired up the 300B again last night, it is so incredibly good with the orthos. I keeps surprising me each time :o

I am glad you still like it.

That C3g drives the 300B so well don't know why anyone would want to use a 6SN7

to drive the 300B.

I am still loving mine, too. How are the C3g tubes selling these days? Still very affordable?

Here they are going for 25€/piece. cheapest I can get them anyway but all NOS.

I have no idea if anyone other than perhaps Xcalibur255 might be interested in these...

 

Received a 1959 Raytheon 5687WA and a Sylvania Gold Brand 5687 with gold pins, probably manufactured in the 1960's, or maybe the early 1970's. (It is perhaps worth noting that Gold Brand, GE 5* and RCA Command were simply milspec JAN tubes repackaged for the civilian consumer market.) I haven't had a chance to do more than ensure that these light up and play, so can't yet say how they compare to the Tung-Sol.

That's very interesting! It appears that you are using a 6SN7 as a driver and the two 5687's as output/buffers. I have heard may good things about Single Power amps. It's unfortunate that the company was unable to survive.....

Those tubes were $10 each about a year ago.
