LM3914 LED driver with integrated LEDs are able to follow the volume amp circuit I’ve used a few of these and many similar to the output of the integrated circuit by adding additional control elements able to control high power loads
CAUTION Be careful is working with high voltage capacitor circuit connections Beware + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles
Circuit 47k potentiometer with a high low audio signal by the lamps burning range can adjust the L1 coil supply voltage for the filter not use happens on but I suggest to use has many benefits known to our network situation in the grave lamp instead 230v ac working with different loads can connect the application lamp cabin plexiglass with a little expensive materials prepared

Tube Amplifier Project Fisher X100A
The next time I started the work and almost six months before the active paper, I finished my amp based on the Fisher working x100a.I need to do on paper for a long time, both in the supply circuit designs amp 2-3aylık at the end of the test phase of an application and a trunk and a very good result.
Many of you have heard the name of the brand, many of you have heard of American-made, maybe Fisher is one of the best konfigirasyonlarından almost serisiA class employee X100A El84 lamps and can produce about revised portions of the power amp, 18w, and did a very nice amp.
