상품 설명
NOS Triotron Valvo ECC83 12AX7 mC1 D6B Long Plates D-getter Tube
Triotron / ECC83
NOS TRIOTRON
ECC83 - 12AX7
The price is for 1 NOS tube. This is a dual system triode preamp tube featuring long plates and a D-shaped getter. It was produced in the 1950s and is very rare, with etched codes from the Valvo plant in Hamburg - mC1 D6B - 1956, I believe.
Tested GOOD with the following values:
Ia1 = 1.1 mA | S1 = 1.6 mA/V | Ri1 = 54.0 | μ1 = 86.4
Ia2 = 0.9 mA | S2 = 1.3 mA/V | Ri2 = 58.8 | μ2 = 76.4
Testing conditions were: Uf = 12.6V | Ua = 250V | Ug1 = -2.0V
Good begins at: Ia = 0.7mA | S = 1.2mA/V
VERY RARE AND HIGHLY-SOUGHT AFTER TUBE!
Shipping via registered airmail with tracking number. Import fees for U.S. buyers are included in the shipping cost under the new tariff regulations. Other methods available upon request.
