GemTune GS-02 KT88 Hi-Fi Tube Amplifier, Tubes:KT88*2, 6N8P*2, 5Z3P*1, Hi-end Tube Amplifier, Single-end, Integrated Amplifier, 100% Handmade

only used for about 20 hours so far,UPDATE NOW USED FOR 9 MONTHS NOW SOUNDS EVEN BETTER NOW ITS BURNED IN, WELL WORTH THE MONEY YOU WONT BE DISAPOINTED ( NOT A CHINESE FIREWORK) when i installed the amp i noticed that one channel was running at 85ma and the other was 70ma. so i turned it down to 70ma this is done by the bias adjuster on the top of the amp as in the picture.The sound seemed a little flat to me due to it not being burnt in yet, to get over this while it is being burnt in i downloaded a free equalizer called peters equalizer .wow what a deference that has made running it through the computer with a preamp inline for the record deck and using spotify for other music it now sound fantastic. i am running it into 2X 8ohm celestion DL10'S. THIS IS A BIG IMPROVEMENT TO THE GS-01 THAT LET ME DOWN IN THE FIRST 6 WEEKS I HAD TO RETURN IT FOR A REFUND AS THE RECTIFIER VALVE PACKED UP, AMAZON DIDN'T OFFER A NEW VALVE THEY JUST SAID RETURN THE WHOLE AMP, SO I DID AND GOT A FULL REFUND THEN PAID AN EXTRA £200 AND BOUGHT THIS ONE GS-O2 WITH KT88 OUTPUT VALVES.

Using the G-02 KT88 to drive my Klipsch RP-260F these speakers have an efficiency of 97db so work well.The unit came well packed and is easy to set up.The overall sound is excellent and if you like tubes the G-02 KT88 is great value for the money.

GREAT LOOKS AND GOOD SOUND LEVEL.PETE.
