Thanks Soumya for the invite, sure will come to your place soonest possible. Also my invite is open too. Dear it is very heartening to note that your father still pursues his academics. Wish him all the best. AND NOW the PORN PICS hyeah:

Please excuse the amateurish pictures clicked with a cellphone.

very nice indeed

Where is the supply board from ?
Link please

 

[lifewater]

Soumya Power Supply board is from our very own Om Mishra @ omishra. Donation from him actually.

 

[saheb11123]

the board looks sweet

the board looks sweet

Thanks, Actually I made batch of 20 PCBs during Pearl-2 phono build GB. There were some leftover. I used few for my own non class-A power Amps. Looking at his remote place and enthusiasm I could stop helping him out from my side.

 

[saheb11123]

you should actually think about selling the boards @omishra


@lifewater waiting to meet you

 

[omishra]

Lifewater, what are those yellow components and circuit for?

My DIY LM3886 kit seems different than yours.

Those are relays on source selector circuit board. Your kit looks like from eBay.

Thanks Om. I have always said that you have such a big heart.

Hi yogi, very smart looking kit you have got. As rightly pointed out by Om, these are relays of the input selector board.

Link of the board is Input Selector

Thanks for suggestion, I will find out how many are remaining. If worth of selling amount I will put into classified section.

What was the specification of the boards?

What was the specification of the boards?

I have to remember all details now! You see here in pictures of lifewater.

These are simple unregulated PS boards on single sided PCB.
- CRC based filter for 4 caps (10mm lead space X 35mm dia, 1/0.1 ohm R)
- 4 on board MUR8xx Fast diode as full wave rectifier. Provision of heatsink.
- 4 switching noise caps for diodes
- 2 x 2.2K bleeder resistances
- 2 X 0.1uF HF filters on rail
Size ~5.25" X 3.5"

Thats all! IMO it should give clean dual PS for amp of these kind which has low quotient current <100mA.
It worked well for Pearl-2 Phono pre amps and my class AB amp build. Now I am planning to use one for my class T 2022 based amp.

You are correct about the config / layout Om.
If Om puts this PCB for sale, grab it. It is top notch.

I can also see it can handle chipamps well..

If it comes to sale I may grab one for myself

 

[lifewater]

Please give your comments on mine. Thanks.

Hi Yogi, as I mentioned earlier, a very stylish kit. From the angle of photograph, power supply looks OK, but the amp kit I think requires some improvement. I dont see the LC network in the output. Also the input caps...... Can you please post close up pictures of YOUR kit in hand ?? not the ones from the website.

Regards,

Lifewater

 

[saheb11123]

There is .1 resistor at output (white cube like thing) and the pink one is the input wima cap, better to substitute it with some good caps or bypass it with some elna cerafine or nichicon muse .....

Yup agreed. Post pics please ..... maybe some caps for you too
