I recently upgraded to v0.9.5.3, and starting to get file path exception when I point fb2k to a folder with multiple single track flac files. I remember it worked with lower version of fb2k. And the new one is still working with single track ape files. Any one has the similar experience?

I had the Wooaudio 3 before, and did not like the flat sounding. I sold the amp, but still have quite a few 6dj8 and 6as7 tubes left. Being wanting to put the tubes to good use, I built this DIY headphone amp. After two weeks tweak and listening, I'm glad that it sounds better than the Woo 3...

Greeting. I am trying to mod/fix Bada Ph12 amp. The Mosfet is dead, and I am not going get rid them totally. Before the Mosfet is a cap coupling 6sn7 cathode follower. I have tried connection HT600 phone directly to the CF and I get loud enough sound out of it. I have two 4K-8 output...

I am going to buy a power choke - 10H and about 150mA. Where is the place to look?

Looking to build one tube headphone amp. Most of the schematics I see use 220uf/400v electrolytic capacitor in PSU. I find in ebay some 2200uf/400v for sale. Is 2200uf a overkill for phone amp? How big is too big for the application? Yeah, 2200uf/400v capacitors are big - 50mm x 155mm!

The power transformer in my 708B amp is wired for 220v. It looks like that there are two 110v primaries connected in series. I want to convert it to 110v. Should I just connect the two primaries as parallel?

A friend of mine gave me a Samsung MP3 player that has some MP3 songs already loaded. It is tiny. It is convenient. But the sound from the earbug is so bad that I could not put up with it. I like my RCD951->MF A300->BW DM305 so much better. But I don't get to play with my Hi-Fi that often...
