40 – 0 – 40 5A transformer Circuit diagram

40 – 0 – 40 5A transformer Circuit diagram The power supply should be capable of supplying the maximum current required with good stabilization. I used commercially available 40 – 0 – 40 5A transformer. The transformer have 6V, 9V, 12V and 22V windings also. The transformer cost me around Rs: 370. Power supply provides […]

Making VCO for MF-HF-VHF

It is a simple Colpits oscillator, but it has a 78L05 5v regulator (not shown) as the supply feed. The 22K and 33K resistors bias TR1 emitter to about 3v DC, which means that TR1 emitter can feed the CD4040 counter input directly when the synth is fed from a 10 volt supply. This is […]
