The Sylvania 6sn7 and RCA 6080 is what I'm listening to at the moment. Easy combo to get used to for cheap. Maybe 15 bucks for both of them?

For a 6080, I liked the Mullard best with the DV336i, although I never had the opportunity to hear the famed and pricey Benidix 6080.

was going to stay with the Sylvania JAN-CHS-6SN7GT + RCA 6080 combo, but cannot resist B.P.'s suggestion.

my HYTRON doesn't say CBS. also it's a 6SN7 GT. what does the "FW" stand for?

 

[Skylab]

CBS bought Hytron at one point, but certainly there were many years where Hytron made tubes before the acquisition by CBS that would be branded only Hytron. I believe the fw indicates where the tube was made. In any case, that is a very nice tube

thanks, Skylab.

i poked around the internet a bit...it was 1951 Hytron Radio and Electronics Company merged with CBS.

here's a scanned 1954 pamphlet:
CBS Hytron tubes - a set on Flickr

guess mine (13th week of 1951) was a stock before they changed the label.

it is a very nice tube indeed. no hum. sounds very "clean"...

new tube combo:

Svetlana 6H13C, freshly arrived from pataburd

Raytheon 6SN7 GTA 280 6-17

alright, how to decode the numbers with the Raytheon?

don't have the camera with me. it is rather short; black base with yellow text.

first impressioon: fuller voicing. like there's "more" on everything...

Can I use the above combo for my 336SE? What kind of SQ can I have? I'm a tube noob here

Can I join in on this thread? I have an Eddie Current HD-300 amp which uses the same power and driver tubes. I want to thank all the contributors over the past 86 pages because the information has been excellent!

I am currently using the HD 300 as a preamp into my Stax srm717 amp and find the combo very good to my ears. Subtle, but definitely there. I have gone from a Sylvania 6AS7G grey plate power tube (lush and balanced) to the TS 5998 and find it adds some needed dynamic punch to the bass of the Omega 2 that I have...and still maintains the great electrostatic mids and PRAT.
Am still rolling in a few 6SN7's to get a sound with more detail in the upper mids and treble...which tube to get a more bold and forward sound in the highs?

Yes. Skylab's recommendation was for the DV336, i or SE.

I always thought that EC was a cool looking amp

If you want more extended highs, try a Tung-Sol tall-bottle 6SN7WGTA - this tube will have black offset plates and a brown base, and is almost always labeled with the JAN-CTL or USN-CTL military designation.

280 = Raytheon manufacturer code
6-17 = Y-WW date code

Thanks Sky...will give it a try once I find one. It was one that was not on the list. Matching up the tung sols might be great.

I have read too that the Raytheon vt-231 and possibly a Sylvania brown base ( not sure on designated number) would be good to try also.

 

[shiaokun]

Oskari,
thanks for the info. i sort of guessed the 6-17 is the production year-week code. too bad it's not a complete year, or maybe you (or someone on this thread) can tell that by looking at the tube? i am attaching a picture. that's a quarter next to it. this is so far the shortest 6SN7 i have.

shiaokun

 

[Oskari]

Based on the looks and the one-digit year my guess is 1956. It can't be 1946 because the 6SN7GTA did not exist until 1950.

thanks!
