I hv sony viao laptop. It works on mains but not working on battery. The battery is not detected & charged.
Battery is ok.
I tried with 2 people but they failed.
Many times people don't hv software. But still they want the user manual. This is because they might be using it on some other computer(friend, college) with limited time. Then they might want to get prepared first.
Many times people learn from user manuals.
don't plug to any power source now.
First check the burnt components.
Normally first the fuses & rectifiers r burnt. Then there is possiblity of condensors in power supply being blown.
Check the output devices of ur power amplifer.
Check whether power supply if based on mains transformer(...
Re: 20dB VHF amplifier
to make it simple:
Every transistor has max output level. The transistor used in ur preamp r very low power devices. Hence u get low output.
To get more power u must high power devices. If u r designing any amplifier, understand the power required by the amplifier. If...
Re: homemade speaker
yes, by increasing the weight of the cone, low frequency response improves but high frequency reduces. Further u hv to check the linearity of frequency response. To check frequency response requires acoustical room & test equipments.
Hope this clarifies what i mean.
Re: 20dB VHF amplifier
This is very low output circuit.
It won't work for ur purpose.
Don't try the way u think. Better go for full tried & tested circuit available on net. Just google & u will find many. In RF matching/return loss is very important.
