headphone amp for Senns HD600

[merlin el mago]

I'm looking for a good sound & simple tube schematic to do an headphone amp for my Senns HD600, I would like to avoid output trasnformers also with not rare valves or very high voltage for B+, suggestions will welcome.

Hi,
I built one after Andrea Ciuffoli schematic for my HD540.
It work very fine (very great dynamic) but pay attention with humm.
I recomend you to elevate the potential of upper tube heater.

Wich is the impedance of your HD540?

 

[ruben alstad]

300 ohm headset you say?
simple tube circuit you say?
inexpensive tubes you say?
might be do able without OT's.

watching this thread.

OK you are looking for a tube headphone amp like my requeriments.

 

[marl0w3]

600 Ohm.
using the indicated schematic you'll can fit with headphones between 600 and even 32 ohms by adjusting the negative feedback.

Try the schematic below.

An externally hosted image should be here but it was not working when we last tested it.

6n6 version has about 200mW output power.

Or his little brother.

An externally hosted image should be here but it was not working when we last tested it.

6n16 version has about 30mW output power.
The photo's and PCB design are for the 6n16 version.

Thanks to share your schematics, really appreciate but I don't have this tube on hand, BTW congratulations very neat & beautiful work.

Could you link me or post the definitive schematic?

There is always John Broskie's Aikido Headphone Amplifier Also check out this and this. Nice thick circuit boards and user manuals available from John.
