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).

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

Brand Spanking New, MINT NOS NIB BRIMAR CV4001 Rare 1956 3-MICA Military Black Plate Square Getter tubes. In white military boxes. STC Footscray Plant Etched Date Codes. Made in England.

CV4001 premium grade version of the CV4005/6X4WA/6063 is one of the best from Brimar.

Tested and matched on Hickok 752, just recently calibrated and modified by Hickok expert to all Solid State to eliminate drift.

Single Tube = $50.

5 of 5 Holy cow! October 19, 2018
Reviewer: Anonymous Person from NYC  
It really blows my mind how much improvement this tube is over what I thought was an already great sounding 1955 Tung-sol 6X4W. Everything the previous reviewer said about the sound I also found to be true. This tube is amazing.

5 of 5 Top recommendation for this rectifier October 2, 2014
Reviewer: M Sawyer from London UK  
Using the Brimar CV4001 in an EE Minimax preamp with Creek Destiny SS amp. I have used many Mullard/Philips EZ90 and Marconi/Osram U78 rectifiers and this one tops them all. It has an open 3D soundstage with a lot of air around instruments and voices and reproduces their tone in a vivid and realistic manner. Brushes moving over drum heads, cymbals, hand claps, plucking of strings, vibraphone pings, etc. sound clear and crisp.  Also a lot better bass, PRAT and dynamic punch that sounds really musical and synergizes well with the great midrange of early NOS Mullard 12au7s. Will mention the great service as Tubemonger provided a replacement tube for free when my first order got delayed in the mail - no questions asked.
