You are looking at a super affordable legend! This is the Project Starlight amplifier. Starlight is a Tube / Opamp hybrid capable of rolling opamps as well as 6 & 12V dual triode tubes. Stock output stage features quad 4562's and she sings like an angel. The amplifier has variable output resistance and a fully dedicated tube heater power supply. Both the kit and built amplifier will include a chassis, power supply, all parts + PCB and tube. Everything you need. Kit shown with optional stainless thumb screws available on our site.

Who we are and what Project Starlight is all about:

G1217 consists of two audio enthusiasts, Myself (Jeremy H) based here in the US and our electrical mad scientist (Frans G) across the pond in the Netherlands. The short story: Frans designs our gear electrically and somehow comes up with this stuff – absolutely a master at his craft. Myself, I handle the physical designs, builds and actual products you receive from G1217. We both really do 10x the work of that brief description, but it gets the basics across. We are all about getting the most for your money which is why we are factory direct only. This keeps prices low and value high. Offering excellent gear over the years, our customers have spread the word which has let us grow from a single amplifier offering to 6 designs with more products on the way!

Features of Starlight:

• Easy Set bias via LED indicators. No need to use a multimeter anymore when rolling tubes! Access from the side of the amp, no removal of top cover
• Easy access to bias trimmers. You can use a jewelers screwdriver to dial in the bias through the top cover, no need to remove the cover to set
• Access to the 6/12V jumper through the top cover, no need to remove the top
• 3 Output impedance settings
  
• Revised protection circuit protects your headphones and audio gear
• 1A dedicated heater power supply for current hungry tubes
• Ability to run a pair (one per channel) or quad opamps for increased output
• Ability to roll several opamps and see what you like
• Designed in the U.S. & Netherlands. Kitted or Built in the U.S. depending on how you order / 5 YEAR WARRANTY ON G1217 BUILT AMPS!
• All parts sourced in the U.S. From reputable distributors, NO FAKE COUNTERFEIT PARTS, CAPACITORS OR RESISTORS!
• Only top quality components used, such as Bourns pro audio potentiometer, Bourns trimmers, Low noise Vishay/Dale RN, CMF and CPF 1% resistors, Nichicon Roederstein capacitors, Neutric phono jack. Ruggedized PCB RCA jacks, Rugged 5a power switch ETC…
• Beautiful piano gloss black .096 thick double sided, PCB with top and bottom ground planes. Will not bend or flex while inserting a tube
• Turn on / off protection for your headphones and audio gear
• Reverse polarity protection
• Chassis is beautifully laser cut and serialized.
• Each factory built amplifier is meticulously hand built and tested prior to shipping. Solder work is outstanding and clean with no flux or fingerprints left on the board. Pride in workmanship is evident from every angle of this amp. What you see in photos is the quality of build you will get!

This amp is open, dynamic and plays with authority. In short, this is not a cheap toy with counterfeit parts on a cheap PCB. This is a beautifully designed & engineered amp you can truly own and enjoy for a lifetime.
