DIY Super Simple Preamp

[vin_eme]

Om, Sachin,

did an analysis and found out that 2 things were wrong
1. 100k and 100 ohms were interchanged

2. Volume pot was bad. Short between 2legs on one channel and second channel was open/broken.

Fixed it and tested with spare NE5532, sounds fantastic....Will be handing over the kit to Santhosh in the coming week.

cheers,
Vincent.

Om,

Sachin infact shipped a replacement opamp as well. But same symptoms. Santosh is planning to visit my place this weekend. We will try to sort it out and update.

I would like to thank Vincent from bottom of my heart for the help which he offered. He spent around 5 hours of his specially on weekend to fix the issue. Next time I will be extra careful with my DIY project.

Regards,

Santosh

ignore the color code and measure the resistors before soldering

Santhosh,

sad that you couldnt be here. You could have learnt the tricks of the trade. Just follow the tips i gave. Will surely help you on the long run.
DIY's are meant to be learning exercises. some times costly ones

I can do that if few more members are interested.I have already got inquires from 3 more members.One full power supply kit would cost you Rs 800(Approx)+ you will need a R-core Amp for this.

Hey all.
I just got the pre amp mode done on my Norge 4242. sounds very natural and pleasing. No scratching highs or bumpy lows. Its worth a try for all into CD music.

My thanks to Murali (murali_n)and other in the form for starting up with this tread.

Hi Sri,

What is CNC phonostage is doing in the SSP thread?

I took back the SSP preamp from FM Mathew Syriac just half an hour back and that's why remembered the circuit vividly.

BTW, I don't need the SSP as I'm going the all B1 way. If anyone wants a fully assembled SSP can ping me. I even have an assembled LDR to spare.
