High μdouble three
pole small 9 GT enlarges the voltage and driving power when working in
magnify circuit. 12AX7A,7025 is the same with 12AX7 and ECC83 in function,
electric parameter, and it is the super of low yawp, and is adapt to use
in plus amplifier as first grade.
Beam power
tube 6L6G, 6L6GA, 6L6GB, the anticathode limit dissipation power of which
is 19W, can be used in the amplifying of A1、AB1 and AB2. They can also
be used in regulating-voltage circuit. They are similar to 5881 and 6L6GC,
and can be replaced by them.
EL34 high
capacity audio frequency output pentode tube's anticathode limit dissipation
power is 25W. In audio frequency amplifier, if single tube is used to
amplify the power of A1, the output power is larger than 10W; if two tubes
are used to amplify the power of AB1 series, the output power will be
larger than 35W. EL34 is the same with 6CA7, and can be exchanged each
other.
