I am using a Sowter 9335. Since my DDDAC really needs a transformer at its output, I figured I could combine the transformer with the volume control. Otherwise I would have use a normal volume pot + buffer.

Hi, are there experiences with HB and Quad esl?
I am planning to build a HB to be used with esl 63. Those speakers short the AMP output if a spark is detecteert by an antenne to protect the loudspeaker. An electronic lighter naar the speaker is sufficiŽnt to provoceren this.
There has to be some kind of current protection, I know that OS does’nt likes current limitting but properly designed it is like clipping. Nobody likes clipping but it protects.
An other option seems to use a switching powersupply, current limit build into the supply as well as softstart.
Any ideas about these?

Nico

Hello . I can ask you some beginner questions: I took up this project again, taking a long break, my idea and building a Honey Badger suitable for pushing 3-way boxes like my Ekta Grande (4 ohm). I intend to recycle psu components of Aleph 2 that I owned. I have 2 toroidal 600w 2x37, can I make a dual mono or e too 600w x channel? x PSU I have 16 cap Kemet from 47000uf 63v, a pair x channel okay? or better than more? ..x testing of H-B. and the next projects, a friend recommends me to buy a variac, and correct? thank you

Hi All,

I'm in the process of ordering parts for an HB build. I plan to use the SMPS that OStripper linked to a few months ago. (The SMPS500R from Connex Electronics +/- 60V version).
Questions:
Is there anything I need to change in the amp circuit when using that power supply?
The system will be: Source > Glass-ware's Aikido 12VAC preamp > Honey Badger > Magnepan LRS speakers (4 ohm)

Any advice would be greatly appreciated.

Regards,

Steve

You should be looking at the Honeybadger's big brother, the Slewmaster. A 5 output pair amp is better suited for the power range you are looking for.
