Tracing The PeeCeeBee

[crosstalk]

Thanks! I like designing classy stuff.

V4H experiments helped PeeCeeBee's Class-AB performance and sonics at 100mA bias cross an important milestone - near zero crossover distortion, usually predominantly attributed to P-P Class-A amplifiers.

As a result, now it sounds classy too.

I intend to drop by in your place very soon with a prior appointment.

You're most welcome! It's always a pleasure to have a listening with company!

So are the V4H PCBs ready to be shipped?

 

[shaan]

They will be once they are home. Details are in V4H GB thread.

A proper PeeCeeBee V4H stereo amplifier is initiated. Probably going to be very non-portable after assembling. Welp, as they say a heavy amplifier is a better amplifier.

The important stuff also arrived this afternoon!

And the lovely smoke grenades.

Seeing those caps for the first time Shaan, what are those named "Punsuma"?

PUNSUMI - and you answered your own question

PUNSUMI - and you answered your own question

There site is pretty bad and slow and does not showup the aluminium electrolytic caps link is broken. Any idea how is the quality and its made in India

I've been using Punsumi caps for many years and these are very good for PSU.

 

[manniraj]

You get them directly as I could not find any online site selling them.

 

[shaan]

AFAIK, these are and were never available online. I always get them from my local market.

 

[shaan]

Nice, eh?

 

[shaan]

A very special PSU is undergoing tests!

At-last. The Amplifier is completed. Too Good to describe just by words, One of my friend said after listening "I am not missing my Class A Amplifier". I can say it is one of the greatest comment on the sound stage of this Amplifier. Very good Shaan. As usual i will not start a new thread for the built journey because if someone wants help on this amplifier he will not have to go through various threads. so will post the images here itself.

I have made this amplifier as a total integrated amplifier. It has Pre Amp with tone control, Source selector & Speaker protection. I would really like to thank you Shaan for this Master Piece.

Being a DIY'er I will be selling this Amplifier to raise funds for another project. I will post it in "FOR SALE" section.

Aha!

Thanks for the kind and encouraging review Sadik. After Rev2 mod I did believe that PeeCeeBee V4 evolved into a DIY amplifier that one can proudly keep besides any other well-regarded Class-AB amplifier and be assured of great musical sessions everyday. Happy to see that all the sleepless nights were worth it. My hearty thanks and congrats to the person who buys the amplifer from you.

Now I wait for comments from someone who used the Rev2 mod on V4 as you did or already have Rev2 V4 PCBs, AND biased it into 1A Class-A. Because during listenings I felt like that configuration has a sonic signature with a special class of its own.

My PeeCeeBee Rev 2 V4 is getting there.
This is how it looks after wiring is completed. Waiting for the front and back panels.
