Sorry if I am asking a noob question here but I do not know much about tubes let alone rolling them. I recently picked up an old used Little Dot II. I have been trying to find information about it, specifically the tube types that go with it. The unit that I picked up has very old tubes on it. It even looks like some of the pins inside of the tubes are snapped/disconnected.
I am now living in Hong Kong, so if I can find some cheap tubes here to use on the Little Dot II, I will give it a shot. Otherwise I will be going back for the summer in Toronto this year.
The sound that I would like to change from the current, I assume stock tubes, is less warm, more transparent, and more bass would be good.
Whenever I do a search, most of the information that pops up is for Little Dot MKII, which I believe is newer and better. I did come across this information from an ebay website. Is it the right information?
The Little Dot II has sharp, dynamic range. Low sounds are really low and highs are really loud. Bass and sound stage wasn't good at first but after 100 hrs the warm bass came through beautifully and sound stage widened incredibly. Voice is super realistic, with more body. I'm using this amp with my PC tower, DAC and Sennheiser HD 650.
