ya don't have 'nuff brain food with these 3 legged fuses ..... ?

ya'll have it chewed , but later ........... I'm not in so big rush ....... about Brunhilde

I asked because I want to purchase the correct tube--some can be purchased balanced, some not. Balanced is more expensive, but maybe necessary?

Well, in that case, I'm screwed....


BTW, I'm in no hurry, either. Still working on the JfetBOZ--which is one reason I love your schematic!!

This seems like an interesting tube. I like the sturdy base!

For what it's worth, I think the 6SN7 is one of the best tubes going.

Coming from you, Grey, that's an excellent endorsement!

I've been studying some of the internet sites for tube newbies, like me, and it doesn't seem so tough.

I could probably put some values to a tube-converted balanced jfetboz and make it work.

For some reason, tubes seem better explained, more approachable from a novice point of view. The higher voltages do spook me a bit. Still, I think I can do this. The cost of these little tubes seems reasonable enough.

Well John, for what it's worth, tubes were the first active electronic thing I learned Not necessarily showing my age to much though it would have benn mid 70s. It was a school(High School, Vocational) project. I beleive a 12AX7 and a 50C5/ch. I've developed a reasonable RF background also. Thing is though, I got caugt up in the trend and all the hoopla of transistors and digital ras-ma-taz like everyone else. I had a 2ch digital recorder sitting next to my reel-reel in 1979(CDs nor DATs were available yet)...
Yea. Also, for what it's worth, the 6SN7 is a great tube. One, if not the, first dual triode. A lot of old tubes are really good performers for audio. Most are a little difficult to use being direct heaters. I'm using 6FQ7/6CG8 on the input of my Aikido and 5687 on the output. I have a handful of 76s and a couple 45s I want to try sometime too...
Try reading some of Lynn Olsen's stuff http://www.nutshellhifi.com/triode1.html
Very enlighting
Anyway, studying JFETs and Triodes in close proximity is good, they are very very similar if you can get by the huge resistances and voltages
Boy, was that OT

you need mu of 33 to accomplish some SUSY with darn toobz ;

6SN7 is good for another things , but not this


go to my www , find "various" page - download my bookmarks.rar and look for few educational links ........ regarding toobz
