6080

If anyone is a headphone fan and wants a good inexpensive Tube Amp...may I suggest the Little Dot MK9. It uses 6SL7 as the driver and 6080 as power tubes. The amp is unique in that it is OTC (output transformer coupled) but, employs an advanced power supply so that it can also be OCL (output...

A couple of years ago, @kward started this thread: https://audiokarma.org/forums/index.php?threads/thinking-of-building-a-low-gain-preamp.783332/ In response to that thread, I ran a couple of experiments with a 6080 that showed some promise, and then promptly put the idea at the tail of the...

So, I'm about to dive into building a low-gain 6AS7 / 6080-based stereo pre-amp, and was talking to a buddy about it and he expressed interest in it, but he wants tone controls and a phono stage. "Ok, sure!", I said. I need ~160V for the 6AS7 gain/output stage (that will be loaded with a CCS)...

I recently picked up a pair of output transformers from a H/K TA-260... 4K CT, with 4, 8 and 16 ohm secondaries. This model used 7355s and was probably in the 30W/ch ballpark. One option would be to make an EL34 amp out of them. But I also have a bunch of 6080s, and was thinking that since...

Anyone tried this? I was given a suggestion that 2x 6BL7 tubes could sound better than a 6AS7G when the drivers were the 6SN7 / 7N7 family. So I contacted my friendly Chinese adapter maker, and had her fabricate the adapter. And bought 4 of the 6BL7's, which are inexpensive and plentiful. Low...
