6SN7 Tube Addicts - Page 279

Nice tube.

247 is the maker's code for NU, this tube was made in March, 1951.

Thx...

I just counted the number of 6sn7s I've purchased from ebay over the past couple of weeks: 36! Is there some sort of shot I can take to break this growing 'hobby'???

Of all the tubes on their way to me, my TS Mouse Ears arrived first. Two rebranded tubes (Motorola and Greylock) at $22. The BEST $22 I have ever spent. I'm listening to Miles Davis KoB right now... And it sounds beautiful ( but in all honesty, it always does!)....

Way too early to give real listening impressions, but long enough to know I am enjoying myself!!

Took about an year in my case. Good luck :)

Well, I had 16 tubes arrive today. A lot of rebrands and only two mystery tubes. Any idea what this is (please)?



No other marks anywhere...

This one was a real mystery, but I sorted it. Just for fun, do the plates give this away? If so, next time I won't get fooled...


Thx...

after the Psvane,  i kinda lost (appetite) what to buy for 6sn7s ...

 

i see brands on the fotos....?

post #4181 of 4478
Psvanes? Hope you enjoy them....

The CBS tubes don't have a makers code, or a year... Unless that xg is the year. I know it is a gtb, but that's all I know...

It's a 6BL7

These tubes sound good if you have a amp that can use them as outputs

Thanks glenn,

Your reputation precedes you... I have no doubt you could pick it. The plates give it away?

It came in a grab bag of 6sn7s... And was supposed to be a 6sn7. Glad the glass etching was still there otherwise I would have never known.

BTW, I was wondering if I could use a multi meter to check for shorts after shipping. Any specific recommendations would be appreciated.

Ps - I looked up the price of am Amplitrex.... Not in this lifetime frown.gif too many tubes to buy!

Also, about 100 posts back on this thread you thought about making a adapter that up regulates heater voltage (6.3 to 12v) to allow use of 12sn7 s in 6sn7 amps. Did you ever do this? It would likely sell like hot cakes!!!!

Not sure what the mystery is here. This is a CBS 6SN7GTB. Nice little tube.
