Managed to salvage a pair of B9A tubes from an old Rogers Console.
 
Rogers 12AX7 - I65 & r3L4 code which is Phillips Ontario.
Phillips MiniWatt ECC85 - tU3 & a "Right Angle Triangle symbol"4C3 code which is Philips Heerlen.
(Filament current possibly a little to high on the ECC85.)

 

 
Now I can play, I have a salvaged B9A socket and I'll make up some plugs for the LD's B7G sockets in the next few days.

  Hi I love music 2,
 
There is much less of a selection of power tubes than driver tubes. The best are the 6H30Pi-DR/6N30-DR  tubes that today run in the $200-$250 range/pair. An excellent and much less expensive alternative is the 6N6P-IR that cost under $35/pair. Don't bother to look for anything else.
 
All these tubes are made in Russia. With the fall of communism the quality went down. It is best to look for older tubes made before 1990 and preferably from the 70's and 80's. Count on a month to receive them (sometimes faster).

Thanks  6N6P-IR is good enough i just need a spare just incase the one i have would give up.again THANK YOU.

Hi I Love Music 2,
 
My suggestion is to save the first pair as a spare and use the IR tubes instead - they are that much better than the stock 6N6Pi tubes.
 
Good Luck!

CRAP you said 6N6P-IR i just purchased 6N6P-i you know what  for $39 shipped i guess it's better than having no Spare at all.

Just test fitting a new design for the B9A adapter. I still need to wire up and epoxy the socket, make the pins and solder the unit together.
A little spit, polish, buffing and it will look good, even though it is a little too tall.

All hail the chosen tube! Nice work sir!

That looks so cool, very nice work. But how does it sound?

 

[TrollDragon]

Thanks guys, it doesn't sound yet as there is still the hookup to do and that tube I just plugged in for looks. I think it is a heptode & triode combined and I just liked the screen on it.

I made an adapter only for octals. Two 6N8S (6SN7GT) as power and one 6N9S (6SL7GT) to drive them. I think this is my cutest adapter and sound is so good that i can highly recommend this kind of thing to anyone. No any kind of hum or additional noise. Even cheapest Russian tubes seem to sound flawless.

I'm so jealous!
 
Would you be willing to make one for my MK IV, if so PM me.
 
You pretty much turned it into the MK 9 http://littledot.net/forum/viewtopic.php?f=9&t=2537&sid=26e07a6b5e4b72fccb7c2aae7f5df775

Hi.

I recently got my Little Dot MkIII and found this nice guide. I'm new to tube amps but I already have few pairs of tubes to replace the mismatch stock pair of 5654's I got. I was wondering how 6N6P compares to 6N6P-IR soundwise? Saw them at 28$ pair so I might upgrade. Also there is these 6E6P-DRY/DRU tubes.. I presume they can't be used on little dot?

Thanks
