Vacuum Tube FU-811 Shuguang Replace 811A High Reliability Precise HIFI Audio

 

Model No: FU-811

 

Vacuum tube 811A is a typical direct-heating triode, the cathode material is thorium carbide, similar to a famous tube 805, only the maximum screen consumption is smaller.

 

811A is another extraordinary one among them. It makes a sound without pretentiousness, "the words are round and round". It can be described by a “plain” word. This may be the original flavor that HI-FI fans often talk about!

 

805 is still widely used in cable broadcasting equipment, while 811A is almost never used in audio equipment. The attractive sound effect of the direct-heating transistor has inspired a group of vacuum tube fans to discover some dust-covered old "tube" to make their own 811A tube amplifier.

 

FU-811 is similar to 811A and can be used interchangeably.
