Little Dot Tube Amps: Vacuum Tube Rolling Guide
Jun 6, 2020 at 5:25 PM Post #12,032 of 13,432
I've currently been running a pair of Voskhod 6ZH1P-EV's for the past year which I swapped in immediately when I purchased my mk3. Have loved the sound but after reading more recent posts here I also ordered a pair of the Yugoslovia 6H5M which I am waiting for in the mail now to see if I'd enjoy them even more so.
Looking to move from the stock power tubes as well and I am torn between going for the simpler and cheaper option of ordering a pair of 6N6P-ir or going with adaptors to some 6SN7's which would be about ~$40 more of investment.

Both seem to have great reviews from everyones comments here and I am finding it hard to decide between the two. Any words of advice? Is the difference between these 2 tubes worth the extra money spent on the adaptors?

thanks!

You can still get tubes for them, I have one of them and I got a full set.
That's good to know, but there are still no options when it comes to rolling.

Can someone please help me buy some genuine Mullard m8100 tubes in the UK?
It is my first time buying tubes and I dont want to mess up
There are so many on ebay and a lot of them look different. Are any of the stores more trusted and known here?
Also how important is getting a matched pair?

nice one thanks!
I was worried about getting a rebranded one or something. I read about some being made in Sydney or something and them being inferior.
EDIT: wow they have been around for 50 years apparently,
this is exactly the type of people i like to order from, rather than some random seller on ebay.

Hello guys, I just registered to comment this:
Little Dot LD1+ seems to be very forgiving for tube rolling, and I've tried several cheap Chinese tubes in default setting:

Tubes that works out of the box:
6J1(of course, it's the default tube :p, sharp cut-off pentode)
6K4(6BA6 equivalent, remote cut-off pentode, I feel the sound is warmer, some crispness is lost but it's still quite enjoyable. I've tried 6K4 from multiple brands, the sonic characteristic is very similar)

Tubes that will work if put a staple on to connect 2-7 pin:
6J4(sharp cut-off pentode, sound similar to 6J1, bass seems to be a little bit more pronounced)
6J5(sharp cut-off beam tetrode, brighter, it's sound characteristic is some what not tubey)
6K5(remote cut-off pentode, almost identical to 6K4)

Tubes I think might work but haven't tried:
6A2
other tubes in 6J family: 6J2 6J3
other tubes in 6K family: 6K7

Hi, I'm finally thinking of getting some C3Gs for my LD MK2. Have seen some adaptors for them but was wondering what setting to put the jumper pins on to use them ( EF91/92 or EF95). Sorry if this has already been talked about, but I did a search for it and cannot find any info. Thanks

All the adapters I have seen are C3g to 6AK5. And therefore, you would use the EF95 setting.

Hi all,
I’ve just bought a lovely little dot mk iv.
I am super happy with the sound, it is well over what I was expecting.
I am currently on probably stock tubes, but I do have some around and I will be swapping them around,
Would I be able to use these ones as power tubes with the required adaptors?
