PeeCeeBee V4 GB!

100mA MOSFET bias will be fine.

I built a couple of ESP P101 in past with Exicon mosfets.
I'm really happy with them. They are not cheap but i think it could value the extra cost, they are especially designed for audio applications in more modern times to replace the sk1058/sj162.

I built a couple of ESP P101 in past with Exicon mosfets.

I have read somewhere that the Exicons perform better than the SJ/SK in the lower audio spectrum.
Would anybody comment ?

I HAVE 2 PAIRS OF J200/K1529 , ARE THOSE OK AS REPLACEMENT FOR THE 2SK1058/
2SJ162?

That depends to a great deal on the topology. In this amplifier I believe the ECX won't cause a noticeable sonic improvement in the LF spectrum. However, I must admit I have not used them so don't take my word for it.

These are vertical MOSFETs with G-D-S pinout. So unfortunately these won't work. We need MOSFETs with G-S-D pinouts.

Thank you Shaan!

Hi
I would like to order 2 PCB's too. Still possible ?

Thanks for your work and best regards
Christoph

Hello cgraf.

Unfortunately all PCBs in this GB are booked/confirmed. I have received requests through PM as well for more PCBs and after the PCBs of the current GB start shipping I am thinking of launching a second GB. So stay tuned.

Thanks.

 

[shaan]

Hello Everybody!

Just received an email mentioning that the PCBs have been shipped yesterday! Expecting them to be home on Monday. (Can't wait )

 

[Nisbeth]

/U.

 

[shaan]

And they're home!

 

[jacques antoine]

Wow nice stack !

 

[Rick G]

Looking GOOD!

 

[shaan]

UPDATE!!!

Assembled one channel and powered it up. A few minutes of trimming and that's it. Flawless operation with pure music and no ill effects. These "black-beauties" are ready to fly!!!

Using KSE340/350 at VAS, Panasonic M and Nippon Chemi-con SXE electrolytics and everything else pretty much same as before.

Cheers!
shaan

Attention!

Second invoices will be sent to GB members starting from June 1. Shipping will follow.

 

[Nisbeth]

Looks really good! Very much looking forward to getting my boards

/U.

 

[franziscko]

And they're home!

Congratulations my friend!!
.....how much???

Hello franziscko.

All of these boards have been pre-ordered in first GB. Second GB will launch in June. So keep an eye on the thread.

All price, order and payment details are in Post 1.

Thank you for your interest.

Hi, is there a BoM for this build please?

The black colour looks very smart indeed.
