Head-Fi - Bijou All Tube Futterman Headphone Amplifier

I hate turning off my Bijou because I can never predict when I will want to listen to it and don't like waiting for the warm up. This is expensive when using Aperex 6DJ8 tubes. Is there an easy way to wire the standard transformer to power the 12V heated Aperex 8416's ?

pabbi, just wait till you hear the Stacker 2. Mine died but the brief time I had it going it was like taking the best parts of the B22 and the Bijou in combination.

Where did you find a case big enough to house the balanced Bijou ?

The only measuring device for ranking capacitors are the ears.

Today a replaced the eletrolytic coupling caps with 80 uF Sprague oil filled can capacitors. It is amazings how much clarity comes thru now. What are the opinions of the Bijou with no NFB powering a pair of 300 ohm Sennheisers? My current headphones are 600 ohm and they definetaly sound better without the NFB. Would the ouput impedance be too high sans NFB to work…

The Nabu isn't really tall enough.

Yes I recently built a Jfet discrete DAC, the first Jfets I used gave a noise very similiar to tube noise, at first I thought it was the 6DJ8's in my Bijou. So yes solid state devices can hbe just as noisey as tubes
