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 649349443_thumb_3915b6e93117f6dbddc53e4e4f70da49.jpg 649349443_thumb_6156bf9a74d719ed51da0117dba2ca11.jpg 649349443_thumb_b34ed0d1fb7f836eec6c814315fe9ee1.jpg 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.
