Mullard CV 2492 E88CC Gold Pin Nos audio Tube 1960s R7B3- Mitcham

The CV 2492 IS a high performance valve that have passed rigorous military specification tests regarding ruggedness, heat and shock resistence, and heater longevity. They have the four moulded seams on the top, heavily plated gold pins, a halo top getter with a sputter shield below (with slight raised indentations at the 3 and 9 o'clock positions on the shield) which give rigidity and lower microphonics.

The ECC88 and the special quality gold pinned variants find use in many pre amplifiers and a surprising range of exotica. Tubes tested on tv7u the Military standards were tubes needed to meet 60% (minimum value). Tv7 testing is tedious and I have spent 12-13 hours a day testing tubes and double testing tubes - if you notice a mistake(like a picture doesn't match the title) please be gracious and let me know. Thousands of tubes to be listed within the coming weeks!

We have over the last 20 years amassed a huge collection of vintage amps/ parts / tubes and are downsizing businesses my husband is owner of VintageBlissAmplification and his work is highly sought after in the music industry. Every tube has been marked for tracking and security purposes - these marks wipe off easily and without the mark no return will be accepted.
