Description Technical Specs
 
NOTE: After spending $$$$ on tooling and various prototypes, we have fitted Special Grade Flying Leads tubes with Custom Bakelite Bases developed in-house. It is a multi-step, labor intensive process. Each lead is straightened and cleaned to ensure perfect fusion with the base pins in the soldering bath. Process is painstakingly slow, so we will be adding a few tubes at a time to the inventory.

Tubes are Plug & Play, Ready to Use, fitted with our Custom made Bakelite Bases (INTL Patent Application in Process).

Brand New MINT NOS Rare 1964 Mullard CV4109 Military Production with Old Shield Logo. CV4109 Flying Lead is Premium Grade, High Reliability Long Life version of E188CC CV4108 7308 valves. (Click Here to read about Flying Leads Valves).

TUBE BASE ON THESE IS SLIMMER, SO THAT IT WOULD WORK WITH SOCKETS WITH COLLARS IN ADDITION TO ALL REGULAR SOCKETS.

Etched SJ0 R4I1
1964 Mitcham Plant Date Codes. Made in Gt. Britain. In generic white boxes from bulk.

This 1960s Halo Getter Mullard E188CC variant is more desirable than the dimple disk getter tubes from the 70s. In our experience, these are probably the best E188CC/CV4108/7308 type tube made by Mullard.

These tubes are one of a kind. No refunds, exchanges or tube rolling at our expense as it says in the Terms and Conditions on the web site.


Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester. New E188CC tests in the 10,500 - 11000 mmhos range.

Single Tube = $175. Select 2 for a Matched Pair or 4 for a Matched Quad. Odd number of tubes will also be matched.

5 of 5 Dead quiet, transparent sound, yet extremely music May 9, 2014
Reviewer: Mute Bonger from Virgina  
Used as the input tubes in my homegrown OTL Aikido 5687-out headphone amp, the CV4109s are the quietest tubes from the 6DJ8 family I have ever tried.  They’re the only tubes that when I insert my Fostex TH-900 (the most sensitive full size headphones I own), I can’t tell if the amp is powered on.  Virtually no microphonics to boot.

They have a very detailed, articulate sound, yet they make music extremely easy to listen to.  The CV4109 are among my top three favorites of the 6DJ8 family, along with the Holland E188CC and Mullard CV2493.  The other two tubes are both warmer than the CV4109, but just a bit less refined.

Price is a bit steep, but remember that these tubes were built so well, that they were meant to be soldered in place.  One set should last you many years, possibly a lifetime if your gear is easy on them.  I tried the 1964 and 1967 versions and found both to sound about identical.  The 1964 may be a touch warmer, but they are so close, I can’t really tell.
