Natural Sound 6CA7-T
Shuguang also uses their new "Super Alloy" technology. Originally applied to aviation, aerospace, and military applications, this technology has been successfully used by Shuguang to accomplish directional solidification and single crystallization. This greatly improves the ability of electron emission and electron current stability.
The Shuguang Natural Sound tubes require additional parts selection (Including thoriated tungsten filament imported from Japan), high-density carbon anode metal from Germany, high-purity high-density graphite, and gold plated pins). Manufacturing quality control processes, improved vacuum techniques and additional burn-in time and testing.
The 6CA7 tube is compatible with any EL34 tube amplifier.
These Shuguang Natural Sound tubes are their premium export grade and purchased direct from Shuguang in China. Beware of sellers selling for drastically lower prices on Amazon, eBay, etc as they will not be the same export grade tubes.
These tubes are packaged in boxed sets of two (matched pair). You need to order "2" tubes to receive this boxed set. If you order "4" tubes we will send a Matched Quartet whenever possible.
If you need one tube select "Single - White Boxed". When this option is selected we will send an un-matched tube in the quantity ordered.
