I actually bought a soha II board as well so I guess I will configure the bijou for high-z phones.  gives me an excuse to get some hd600s just ordered almost all my parts; can't wait to build these amps.

Iv´e found some nos tessla and tungsram ez81 pretty cheap. Would there be any benefits them instead of new JJ or EH?
 
Thanks!

here are some pics I just started populating; waiting for my partsconnexion order to add the caps and stuff.    still trying to figure out what I'm going to use to case this.

I recently bought the balanced version originally built by pabbi. I replaced the two stereo potentiometers with a balanced stepped attenuator(which is working out great). The nfb pot wasn't originally installed. I would like to install it so it could better match my low z cans. I'm trying to decide what pots I could use. I would like to limit it to one pot but I can't find a 4 pole 250k pot. Could I use a balanced 250k stepped attenuator?

Sure - you could even use a 4-gang switch with only a few positions, if you knew what value sounded good with your low Z cans.

 

[moodyrn]

Cool, how do you wire it. I'm a little confused by the diagram on the website.

 

[moodyrn]

nevermind, i just figured it out.

 

[pabbi1]

Ok, I am curious - all figured out - and, if so, how does it sound with the HE-5?
 
Sorry, with the forum change I can't post from work, which really cuts down when I can... 

 

[moodyrn]

Right now I'm only able to get low to medium volume out of the HE-5s. When I crank the volume up, it distorts. The nfb pot suppose to solve that problem(from what I've read). I have to wait about 10 days before I receive my pot to really test it out. But the sound I'm getting at the lower volumes is outstanding. I did a mod to reduce the sibilance on them, but with this amp, I was able to undo the mod. The sound is clean, transparent, and lush. I'm really looking forward to installing the nfb pot. This amp reminds me of what they sounded like out of a WA22 I listened to at a meet recently. It was on that amp when I noticed that I didn't need to mod them to reduce the sibilance. So I'm please that this amp matches the HE-5s sonically.

Pabbi 1 I have to say you did a great job on this amp. I think it's still the only balanced bijou that's out there. This amp is completely silent, even with my low impedance cans. That's a great feat for an OTL amp. One day I may recase it to show off the tubes outside the amp(the glow of 10 tubes at night with the top off is a wonderful sight), but I'm really happy with it. It makes my sextetts sound unlike any sextett I've ever listened to.

hey guys just finished populating my bijou psu and had a quick question.  Do I need the 100k resistor in order to test the power supply? or can I just plug in my dmm and configure the voltage?    I don't have a 100k 1 watt resistor on hand so just wanted to see if I can get by without it. could I string some resistors together? does it have to be 100k?  if so its another order from mouser!

You could string together 4 25k 1/4 watt  resistors in series which would be much easier to find in a parts box.

Has anybody here tried pairing HE-5 or HE-5LE with bijou??
 
I heard HE5/5LE is pretty power hungry. =)
 
Sam.

 

[pabbi1]

I heard it with a balanced Bijou, which had plenty of power for the HE-5, Moodyrn has the unit now, and I know momomo was using it with his HE-5. No idea about SE, unfortunately.
 
Oh, and it sounded really good BTW.

 

[SBoy]

Great! that was the reply i was hoping for =)
