My "Bad Boy" had good bass quantity when paired with a tung sol 5998. The detail and holographic soundstage were the best part of it to me. I liked it so much that even though I sold my 336i a year ago I wont sell my Bad Boy just in case I need it later.

95 pages is a lot to go through!
Is there a specific tube number for the front and for the back for the darkvoice 336i? There are a tonne of tubes for auction on ebay and apart from 6080 6snt etc I have no clue.

what happens if I buy a wrong tube? will it not fir or poke a whole in the universe?

well there are a lot so I don't really know what I should be looking at. What I am doing is finding one, copy the number and then search this thread to see if it is mentioned.

I figured if there was a specific number or numbers it would be easier.

for example there is a FS right now here where the seller's wife is going to throw out his tubes...sounds like an opportunity but no clue which ones would work with the DVi

thanks!

Stick to the basics:

Front tube is a 6SN7: 6SN7GT, 6SN6GTB, 6SN7GTA, 6SN7WGT, 5692, VT231.

Back tube is 6AS7: 6AS7G, 6AS7GA, 6080 - and acceptable subs are 5998 and 7236, although those are much harder to find.

Start with an RCA pair - 6SN7GT and 6AS7G. These are easy to get, and relatively cheap. Then you can upgrade from there is you are so inclined.

I bought these yesterday and now realize some may not work on the DV

VTG Electron tube _ 6080 (T_262)
VTG Radiocoin vacuum tube _ 6SA7 (488)
VTG Radiocoin vacuum tube _ 6SD7 GT (497)
VTG Raytheon vacuum tube _ 6SA7 (446)
VTG TRAV-LER tube _ 6SN7 GTA (T_060)
VTG electron tube _ 6AS7 (T_145)

so much to learn! (first thing I learned, don't go on ebay while under the influence of neo-citran and cough syrup!)

p.s. thanks skylab sorry to be a pest!

6SA7 (S first, then A) will definitely NOT work. totally different tube from 6AS7 (A first, then S).

6SD7 - also not usable.

The first one and the last two on your list seem to be good, although it doesn't say what brand they are (no clue what "TRAV-LER" is - maybe some kind of rebrander - there were a lot of rebranders back in the day - in the USA, almost all tubes were made by GE, RCA, Sylvania, Raytheon, Tung-Sol, Western Electric, and Ken-Rad. Even "big names" like Westinghouse were 100% rebranders of the others' tubes.

I think they are all Raytheon
are the non usable ones for me good for any other headphone amp? I would give them to anyone who could use them as they are no good for me!

I have never seen an amp that uses a 6SA7 - it's said to be a "Pentagrid Converter" type - I don't even really know what that means - but it isn't a dual-triode like the 6AS7, or even a pentode, or rectifier tube...

The 6SD7 is a pentode, slightly (but not usably) similar to the 6SJ7 used in the DV337 - but again, not possible to use in the 337.

So no - I would say those tubes are headed for the trash heap.

The 6SN7 and 6080 should be fine - you CANNOT use the 12SN7. 12SN7 is a 12-volt version of the 6SN7 (which is 6-volt - that's what the first digit in the tube type indicates).
