상품 설명
Philips / ECC83
This listing is for a Philips ECC83 - 12AX7 tube, either NOS or lightly used, and it comes with its original box. This is a vintage SUPER RARE tube with the code mC5 𝛥8D, a dual triode preamp valve made in Holland. It features long plates and a D-getter.
The tube has been tested and shows VERY STRONG performance with BALANCED triode sections as follows:
Ia1 = 1.2 mA | S1 = 1.6 mA/V | Ri1 = 48.7 | μ1 = 77.9
Ia2 = 1.2 mA | S2 = 1.7 mA/V | Ri2 = 48.7 | μ2 = 82.8
Testing was conducted at: Uf = 12.6V | Ua = 250V | Ug1 = -2.0V
Good performance begins at: Ia = 0.7mA, and 100% is Ia = 1.2mA.
This is a SUPER RARE TUBE, especially one that tests perfectly like this!
