1 pair E188CC 7308 Mullard/UK --- NOS/NIB --- Never Used

Type VR1

Made by Mullard in their Mitcham plant in UK

The E188CC is a low noise, long life tube.
It offers a higher resolution compared to the E88CC.

Suited for preamplifiers or phono stages or CD players.
Can be used as substtute for the E88CC.

But: It draws 330mA on the heater. The E88CC draws 300mA.
So make sure the PS of your amplifier can handle this.

"Minimum Good" on my Hickok 539B is 7'000.

Specification for new E188CCs is 12'500.
Readings: 17'000/17'500 (36.0/36.0) - 17'000/17'500 (36.0/37.0  --- (mA/V*1000 and mA plate current)

Date codes for the 2 tubes are: R2E3 and R2E2.
That is: Mullard Mitchham - 1972 May. Week 3 and Week 2
