Frequently Asked Questions
Can I connect my powered/active speakers?
Yes, through the stereo line out (on the first prototype, it was a mono out but the final version has a stereo line out). This will let you control the volume and source with the Billie controls. Sound will be processed by the tube preamp and DAC, however the amplification will be handled by your active speakers.
Does the Billie have a USB input?
No. No USB input was a hard decision to make. But the reality is that slapping on a USB DAC is easy, making a good USB DAC can be rather tricky.
As we saw this product as being used mainly as a living room system, where SPDIF is more prevalent than USB, we went with SPDIF. We’d rather do less well than try to please everyone with a bloated inferior product.If you still want to use USB there are definite jitter and noise isolation advantages to using a usb to optical converter cable.
How long do the tubes last?
Tube lifespan is variable. Under normal wear, the tubes should last you between 10,000 – 15,000 hours. If you listen to your amp for 6 hours every day (without skipping a day), the tubes will last you between 4 – 6 years. Tubes are fragile when hot. Do not knock them about and avoid handling them when hot.
Tubes will give you ample warning before dying: you will notice that one channel plays louder, slight distortion, or some strange sparking inside the tube when you turn on the amp.This is not dangerous but their end is near.
Are tubes difficult to install?
Changing tubes is only slightly more challenging than changing a lightbulb. The tubes on the Billie are easily accessed from the top, there’s no disassembly required.
Do the tubes need biasing?
No. The Billie uses preamp tubes. Only power amp tubes need biasing.
Do the tubes get hot?
Yes, they do -think 25w light bulb. Not enough to cause serious burn but tubes are not meant to be handled when hot. Keep them out of reach of ‘little hands’.
Where do I buy tubes?
The tubes used in the Billie (ECC99 or 12BH7) are very common and easy to find. You can buy them locally at hifi and music stores. Online, they are available on our website (soon), Amazon, and Ebay. We recommend getting a ‘matched pair’.
What’s the difference between regular & gold pin JJ tubes? Can I install gold pin tubes on the non-SE amps?
The JJ ECC99 Gold Pin is based on the same construction as the original ECC99. The internal components go through additional selection and processing during assembly. These tubes do test more consistently and have a lush and open character with an extended frequency response. You can install these gold pin tubes on any of our amps.
