QUICKLINK :
SIEMENS TYPE AVR
SIEMENS 6GA-2491 COMP. AVR

This is the replacement of SIEMENS 6GA-2491.
Note that the inner design is completely different
from the original and has overcome all the
problems of original design. Overall its much
improved in every aspect. The build quality is
first class and practically it will never malfunction.

 

This is a subtractive regulator connected to a
compound circuit. This set up is adjusted to
provide a voltage higher than the rated voltage.
The purpose of this regulator is to shunt the
excess exciting current in order to maintain the
voltage at its rated value.

QUICKLINK :
Hyundai HDEC1000 AVR
HYUNDAI HDEC 1000 COMP. AVR

This is the replacement of HYUNDAI HDEC 1000
 

This AVR has no need for any kind of modifications.
This goes for the cables as well as the mounting.
Its all the same except one thing, its better.


This is a special analog and digital hybrid design
that combines the best of both world.

 

As for the main operation, the AVR is pure analog.
No operation temperature can change it behavior.
No hangs, no restart. Never. It will just work.

 

As for the digital potentiometer, the AVR is also
digital -as the original- so you have the same
functionality and absolute compatibility.

 

Note that (as with every other compatible AVR

we make) the inner design is completely different from the original and much improved in every aspect.
