PeeCeeBee

[shaan]

I haven't better way copper protection....this is a diy pcb.

That's the true face of PeeCeeBee.

BTW The first PeeCeeBee absolutely hum free! The separate inp GND connection do the job well.

It was Pete's suggestion while I was drawing the first V2 a year ago, hope we'll see him again someday.

And Congrats man! Nice plots.

I will highly recommend this pcb for the one pair version also.

PeeCeeBee from Shaan, I'll complete it this weekend.

Thanks shaan for pcb, fets and parts.

O, is it possible to buy a couple of pcbs?

My pleasure.

Looking forward to your impression!

PM me with location details.

If i'm looking well your plan is to power this with +/-35v?

 

[shaan]

Kunal's PS for V2 is +/- 45V.

 

[thimios]

I see 15k emitter resistors?

 

[shaan]

That strip looks violet to me.

Post#1 updated with V1.1 and V2 info.

I am thinking of using passive volume ( assume input voltage is ~ 1Vrms) by using R input = 47K, and R feedback = 3.3K / 100 Ohm (to get gain x34).

Any concern on that? Thanks.

Black PeeCeeBee

Here my new PeeCeeBee, tested with 25vac. Now it sounding really nice. It's PeeCeeBee

Hi QQ!



Looks better than mine!

I can't see the input cap. Is it DC coupled now?

Yes.

My Peeceebee, tested with 30vdc, It sound beautifully. Is it true that it don't need input capacitor? Thank you Shaan.

If your source out is at 0v d.c you don't need an inp.capacitor.
Be careful,always check the source d.c out.
Can you share the schematic and pcb for this capacitance multiplier?

Hi thimios,

I see my name on the board. Check the thread on the CM supply:

Looks like a slightly different layout but similar to mine.

Ok i see this,nice pcb.
