PRE-AMPLIFIER TUBES

Mullard CV4024

NOS 1984 Mullard Blackburn UK made CV4024 made for the RAF. These tubes are the best NOS production available for replacing ECC81 or 12AT7. With the famous 'copper anode'. Price is for a matched pair of 2 tubes. The Mullard ECC81-CV4024 has the CV4024 markings which were the UK Government designation that indicated this is special quality RAF valve that was specially designed to work in the most difficult operating conditions. This valve was specially designed for long life and be shock resistant up to 500g and with a high temperature rating.

 

The CV4024 has the famous double ribbed ladder plate anode structure and feature large wide ribbed plates with special copper plate supports that suppress microphonics which makes these valves very low in noise as well as microphonics. They were supplied to NATO forces across the world and therefore used the highest quality components and underwent strict quality controls. They are simply made better; they last longer, have less noise and have conformity to the high specification design parameters. So when you compare this to modern ECC81 and you will understand why we do not stock any of modern made ECC81. When you listen to these you instantly get that classic Mullard sound in audio application.When used to drop the gain in a guitar amplifier or pedal you get that dynamic Mullard tone.. Sonically the valves are warm and clean with excellent top end extension.

This is certainly the best Mullard ECC81 ever made and a great valve to use in guitar amplifier as well as high end audio due to its outstanding performance.

CK 5755 Western Electric WE420A

Matched RARE Western Electric CK-5755 tubes in pairs. One of the best replacement tubes for a 12AX7, ECC83, 5751. Longlife 10.000 hours. Tested en matched on Amplitrex AT1000. Matching ADAPTERS from 12AX7 ECC83 to 5755 available! Price = for a pair of 2 tubes! This CK-5755 is a double-triode made by Western Electric (USA) for Raytheon. It has same specs as 12AX7A / ECC83 / 7025 but with different pinout for Pin 2+3 and 6-8 (see data sheet). For use as 12AX7 an adaptor or an adjusted socket wiring for pin 2+3 and 6-8 is required. Western Electric marked this tube WE 420A for their own brand. The CK-5755 "features special cathode springs which reduce microphonic response. This characteristic is controlled by a "microphonic stability" test for balance in which the tube is tapped at shock levels of 400 - 600G."

 

One of my customers bought this tube with an adapter for his 12AX7 based amplifier. He reported back to me: 'best I ever had' even NOS stuff like Mullard is nowhere near the performance of this tube.....
