I just picked up an older Little Dot 2, not the plus version. So far I'm really enjoying it! It's even managed to tame the high end on my Grado 325 E's Being completely new to tubes I was wondering if anyone had any recommendations for tube rolling. Thanks!

I have a Little-Dot II+ which uses the same power tubes.

I assume that your amp came with Chinese 4P1S/4P1S-J power tubes (the bigger tubes in the rear)? The only other power tube that I know of that will fit is the Russian 4P1L tube (Spelled 4П1Л in Russian). On my Little-Dot II+ it made the unit run hotter but they sounded great.

The driver tubes (smaller tubes in the front) of the Little-Dot II should be either Chinese 1B2 or 1K2 tubes, cheap Chinese tubes for which there are not many substitutes. It wasn't until the II+ model that they started using EF92 tubes for the driver tubes, which have many more substitutes. If your model comes with 1K2 tubes, supposedly you can swap in 1T4 tubes, but I cannot verify this.
