>>PRICE REDUCED
I am selling a pair of genuine framegrid goldpin Telefunken ECC803S tubes.
Both tubes have the same ULM factory codes U1206300P.
Both tubes were also briefly checked for correct balance in high end preamp - both channels are equally loud. They are guaranteed to have as little noise and microphonics as it gets given their used condition.
I tested these tubes very carefully on the calibrated tube tester Elpo P508. Test environment and correct settings confirmed by external digital meter’s readouts are shown on the pictures. Mind that this meter on its outs shows half of the actual current flowing through the system meaning 0,27mA shown on the digital meter gives the actual value of 2x 0,27=0,54mA of the system. This value is also shown on the analogue mA meter on the tester (lower scale) - check the pictures.
Additionally for the peace of mind of a buyer, after measurement under correct datasheet conditions for this tube I lowered measured test results by 5% so as you can see the lowest section of the “lesser” tube shows 0,52mA. Both tubes were measured at the same point of time under exact same conditions.
Test settings:
Va=252V
Vf=6,3V
-Vg=2,01V
Test results ( after lowering them by 5%):
#1
Ia1=0,70mA
Ia2=0,65mA
#2
Ia1=0,52mA
Ia2=0,67mA
Price for one PAIR of tubes as described.
Shipping within EU with priority registered mail = 8EUR. Other shipping options on request.
No original packaging but I know how to pack these tubes using sturdy plastic pipes filled with buble-wrap so that nothing can happen during transit. You don’t need to worry about preserving prints - they will arrive intact.
