Have you tried different interconnects and some other source? It could also be a loose connection on the pot that is shorting into the case.

Very cool!!!

The plug fits into a Stax socket on this one so that's an improvement...

Ahh... that puts a small snag on the whole thing. You could just replace the diodes and check the input voltage into the bias circuit to see if it is up to spec.

Is it mil-spec?

Very nice!!!

It is. They've also come up with larger diameter now so they can also be used for the power wiring.

That must cost extra then...

No way dude!!!??!!

If it is the Jupiter wire then it is very good indeed.

Blah... find the Stax F-81 with the amp busting sensitivity of 78dB/W/1m. The stators were also uninsulated so the diaphragm just arced if you drove them too hard.

There is definitely something wrong with the bias circuit so I'd send the amp back.

Sound Lab?? Stunning speakers to say the least...

It's the standard Headamp "Hybrid PSU" board used in both the old BH and the KGSS. The amp board is also from Headamp so I'm guessing Justin sold them to him.

With the amp set to RCA the - side of the amp is grounded.

Me too by a huge margin. A lot of them yes...

The circuit board is held by two screws on each side but there are lots of things that could have been done better. Sound is good but I don't have any bass now for some peculiar reason as it was there initially... \

If it is the unit that was on HF then it's one of mine. You can't go wrong with the normal bias Lambda and the Signature. Another, more obscure version, is the Lambda Spirit (aka Pro Classic in the West) which was the first "budget" Lambda. It's basically the sound of the Lambda Pro with none of the drawbacks.

Nice!! One of my old ones I presume...?

The bass deficiency is mostly gone now thanks to some running in on those massive output transformers and... ehhh... my mistake. It seems that the RCA/XLR switch doesn't work by turning one off in favor of the other so XLR cable was causing some trouble even with the BH turned off. This is what you get for not including an instructions manual which I wouldn't have read anyway...

Sorry, fresh out of Pro's or any Lambdas for that matter. I own a few in Japan but the scene has been so quiet over there lately that saving up for a shipment isn't going too well. Very cool!!

I just wanted to post a quick update. After about 10 hours of use there is very little bass and the whole sound is rather thin. I knew it was going to be a bumpy ride for the first few days but I hate running in new gear!!! I'm going to let it cook overnight feeding one of my Stax amps and see if it is better in the morning.

I feel a bit ripped off when I buy the 100$ Stax replacement cables but 1500$ is simply insane. I especially like the no warranty bit so it is basically a good old fashioned scam.

Why anybody would pay 1500$ for a recable is beyond me. That's the normal retail price of the 4070...

The nasty people at HC which don't like the demigods at ALO and Jena. It's all a gigantic plot you see, involving fairies and pixie dust but not in the normal, magical Jena labs way. It's a bit like the Lord of the Rings but without the rings and the quest is for audio goodness...
