Most probably yes. Just send us a message and we will add it to the list.
Sorry, we cannot ship to Russia.Last updated:
The Billie amp is covered by a 5 year warranty against manufacturer’s defects from the date of purchase. This warranty only covers defects in materials and workmanship. The warranty does not cover normal wear and tear, excessive abuse or misuse by misuse, cosmetic issues or modifications you made. Opening the amp voids the warrantee. The warranty is only applicable to the original purchaser and is void if your product was purchased from another person or an unauthorized dealer.Last updated:
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.Last updated:
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 so we went with SPDIF. We’d rather do less well than try to please everyone with a bloated inferior product. Many macs have optical built in to their headphone out and if you still want to use USB there are definite jitter and noise isolation advantages to using a usb to optical converter cable.
I have yet to try these but FYI, here are some USB to S/PDIF Converters available on Amazon:
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 however 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 (not dangerous). This means it’s time to change them.Last updated:
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.
No. The Billie uses preamp tubes. Only power amp tubes need biasing.Last updated:
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’. (Someone asked us if the tubes would burn his underwear if he left them on his amp. Ok, first question is why would you wanna do that? We cannot condone such use, but no, your house won’t burn down.)Last updated:
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 Amazon, Ebay and on our website. We recommend getting a ‘matched pair’.Last updated:
What’s the difference between regular & gold pin JJ tubes? Can I install gold pin tubes on the non-custom 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.Last updated:
