Bijou All Tube Futterman Headphone Amplifier - Page 281

post #4201 of 4211

Yeah, it was a very fun build. A few issues, but there's lots of knowledge in this tread. Too bad it's not too active anymore.

 

I had it at my meet this weekend and it really was the HD800 killer. Lots of wonderful syrupy tube fun. :)

good to hear . Post a pic of the completed amp. I didn't check but did you include all the mods too?

It's actually listed for sale with pics there. Selling for parts costs of course.

Cavalli's website has been updated and most of the images for the bijou will not display anymore.

 

Does anyone have the schematic for amphead's mod?  And the drill templates would be nice also...  

 

thank you!

I second that.

 

I have a kit from glassjar/Jeff ready to go. I can determine most of the caps but not the resistors. I've searched this thread and with Google but no joy.

 

If anyone has the v2.0 BOMs for the amp boards and PSU board, parts designations, and schematics, I will be grateful and in your debt.

Google waybackmachine.
Type cavallaudio.com into search window.
Try various dates between 2007 and Feb 2016. Most of the information is there but I cannot find a saved page for PSU schematic and a few others. Better than nothing.

I have alerted Alex to this problem. He is at CanJam so it may take a little longer to get fixed.

Now would be a good time to dream up the amazing chassis to house the amp in wink.gif

Thanks dB, and thanks to Alex. 

 

Hmm, maybe a Bijou UFO Double Decker.

Yep, thanks!

Thinking Padauk wood and green tinted glass

I am a big fan of the 6n23p, and think they are a serious upgrade over the 6n1p, especially the -ev. I also liked them in my source far better than the stock EH 6922 (iirc), but not as well as the CCa (the eventual winner), which is teamed with some 1980 date code 6H30-DR, which might well be masking everything else. Sadly, the amp I targeted the 6n23 for (Raven) is now in other, more capable, hands. I was also wanting to hear some feedback on the 6n23 in the LF, and dedicated my remaining tubes for someone to roll these in, but haven't heard yet... but, didn't find the 6n23 until after I'd sold the Bijou.
 

 

@pabbi1 i know it's been a while since someone got the idea of hooking Bijou to speakers, can you or anyone share the word here - is it really worth the effort of doubling the Bijou circuitry just to run the speakers?

 

I have full range Audio Nirvana AN10, inside EZ-10 back-loaded horns enclosure. So far I was running them from my old restored sansui au-4900, and after todays trial (speakers connected via tiny cellphone-handsfree-cable) they sounded wider and deeper when fed from Bijou, but with higher volume the bass got distorted, I wonder whether this was due to high wire resistance, poor connection or i've simply hit amp limits.

 

So basically i'm deciding whether i'm starting new project or upgrading Bijou. But I like the idea of OTL

If upgrading - I should protect speakers with relay, right?

Do I need to change feedback, somehow?

What output power Bijou provides per channel?

 

As this is probably my first post here - I'd like to say *THANK YOU* to all of you who share it's knowledge - thanks to that I was able to stay unnoticed for years :)
