Hopstretch Posted August 11, 2008 Report Share Posted August 11, 2008 I know they don't get many (any?) mentions over here and this will probably mark me as irretrievably jejeune -- but, for the money, I've been pretty happy with the Little Dot MkIVse I picked up used on HF. Anyway, their new balanced tube amp is apparently now available at a fairly tempting $724 shipped to the U.S. and I wondered if anyone had any thoughts on the basic design? Haven't been able to locate any specs, though they explicitly say it was designed to be able to drive K1000s. Any idea what the driver tubes might be? Pity about the gold tube sockets, but what are you gonna do? Quote Link to comment Share on other sites More sharing options...

Hopstretch Posted August 11, 2008 Author Report Share Posted August 11, 2008 If so, I apologize but I couldn't find it. Or any other mention of Little Dot, hence my groveling intro. Edit: Aaaand ... here it is of course. Off to do some reading. Please feel free to delete this. Quote Link to comment Share on other sites More sharing options...
n_maher Posted August 11, 2008 Report Share Posted August 11, 2008 No worries, I can't find it either but I know there was some information posted at some point. I have several questions/concerns about the design of that thing and the chassis that they have it shoe horned into. At first blush it's pretty similar to the Menace but with double the output tubes which means that they've got a lot of heat to deal with in a really small space. As it is just the heaters for the output tubes are dissipating 60W. And if they were trying to get the specs similar to Pete's HA-2 there's a ton of heat generated by the cathode resistors and I don't see anything near big enough to deal with that. Hell, on the Menace I had to use 50W power resistors and external heatsinks to keep things in line. Quote Link to comment Share on other sites More sharing options...

Hopstretch Posted August 11, 2008 Author Report Share Posted August 11, 2008 Thanks Nate. If I do take a chance on one, I'll be happy to send it up your way so you can have a listen and a poke around inside, should you care to. Quote Link to comment Share on other sites More sharing options...
Hopstretch Posted August 21, 2008 Author Report Share Posted August 21, 2008 Looks like you were right about the heat issue. The first ones have started to arrive and, according to the HF thread, they now have (loud and crappy) cooling fans shoehorned into the case.

spritzer Posted August 21, 2008 Report Share Posted August 21, 2008 Guess it was far too much work to redesign the PCB with a lot of ventilation slots and a new chassis design... Quote Link to comment Share on other sites More sharing options...

Smeggy Posted August 21, 2008 Report Share Posted August 21, 2008 Hey, that's a pretty good idea. I wonder if I could put fans in my headphone cups to keep my ears cool. shouldn't interfere with the sound too much. Hmmm, I see a patent with my name on it... *strokes chin* Quote Link to comment Share on other sites More sharing options...
Voltron Posted August 21, 2008 Report Share Posted August 21, 2008 I'm going to be laughing about those fans for fucking ever. Classic. Quote Link to comment Share on other sites More sharing options...

Hopstretch Posted August 21, 2008 Author Report Share Posted August 21, 2008 New. Custom. Title. I do feel bad for them. Their US agent is as nice a guy as you could hope to meet and they were really, really good about a resistor issue with the MkIVse that affected me and a few other owners on HF. No fuss, took it straight back and sent me a new one -- and I was the third owner of that particular unit and said so. This looks like last-minute panic after a few early-production models went up in smoke. The designer was saying on their forum quite recently that it would be passive-cooled only.

JimP Posted August 22, 2008 Report Share Posted August 22, 2008 phhhttt! I'm going to get one anyway. I don't use headphones that much these days, but the few phones I've kept are terminated in 4-pin XLR, and I have balanced source. For US$700, I'm willing to give balanced a try.
