Recommended Posts

Item: Grant Fidelity (Shuguang) KT120 X 3 tubes
Location: Perth
Price: $150 plus delivery
Item Condition: Very Good - Recently tested but never used
Reason for selling: KT150
Payment Method: Pickup - Cash, Paypal, COD Only
Extra Info:

I purchased a quad set of these for my Audio Research after reading great reviews but one of the tubes died when I first installed. I had the bias setting on high at installation for that tube. Since then I have moved onto the Tung-Sol KT150. Only last week I had the opportunity to test each of them to identify which of the tube is faulty with the help of one of my new audiophile friends who has a tube tester. His results are shown next to each tube in the photos below. As I have learned, you must always set the bias to minimum on an AR amp when installing new tubes.

 

As you can see, all three have very closely matched electrical readings and would suit amplifiers that uses matched pair plus you have one to spare. The faulty tube had a reading of 30MA, which I am not selling but can throw it in for free if you would like to have that too. All three have had less than one hour of use - or in brand new condition if you can still call it that way.
