12V DC Step Up converter old circuits

This are 12V DC step up converter circuit. They act Convert 12V DC voltage from a typical battery to boost voltage up. Two old circuits below can power output to dual voltage +37V GND -37V and +50V Gnd -50V at 2A to 3A output. Although these circuits are very old. But some friends still need it. As a way to repair.

12VDC to 37V DC converter by SG3524

Hello there!! How are you doing?
When my friend wants DC to DC converter circuit +37V GND -37V sizes use an automobile s have Voltage 12VDC. He takes this circuit goes to Power Supply with , Mosfet Power Amplifier 100W RMS. A hand sees 12VDC to 37V DC converter Circuit this. Will use prominent equipment interesting be IC SG3524 (Regulating Pulse-Width Modulators) Then be usable easy and convenient. Besides still power mosfet number BUZ11 6 amounts are perform drive a pot modifies the Secretariat of the Senate runs away to give electric tall many power. The detail is other see in circuit picture sir. Hope you guys had a great weekend.

12V to 50V dc converter for car by TL072 + 2N3055

I used a main part and 2N3055 Transister and IC TL072 for pulse oscillator generator.
The output have voltage +50V and -50V at 2A to 3A.
You must is used this circuit for audio sound automotive or motorcycle amplifier.
