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.
The purpose of this work here share the Mikes separate both lamps are curious buddies, visitors will see latest road show, to help them in the future, add Ricky as an amateur production in Turkey, who was fond of that tube amp and toplamakdır to increase interest.
About a year and a half ago and here I share the single end EL84 amfimin then and now is more powerful and good for a successful EL84 push-pull amplifier operation.

13.8V 10A Power Supply Circuit L4970A
L4970A Switching Regulator IC, bjt transistor mosfet output alone, i.e. without connecting to the 10 amp power can give. Accordingly, in case the other regulator according to the larger entegrelerine (multiwatt15v) L4970A 13.8 Volt 10 amp power supply, the output voltage can be adjusted between 5 k potentiometer as the author out of the 13.8 v 9.14 v and used. Inner diameter of 23.6 mm, the width of the toroidal took off 14.4 mm, height 9 mm diameter L4970A DCDC converter circuit diagram, pcb layout, and Bill of materials.
