Hi Shaan,
Very Nice work on the V2. I am planning also to make the double barrel VSSA with ±56 to ±60V, but I was thinking since we are running this on higher voltages and higher power, stability on the input pair would be beneficial. any thoughts?
Thanks

Hello rawbas.
The default transistors are stable at upto 56V supplies. I haven't tested the amp at 60V so can't comment on it. I guess the same transistors will work but the 27K resistors might need to be increased to 33K-39K.

Very Nice.. did you already make a thorough listening test?
I would like to hear your impression on the V2 soundwise 😉
A lot of people here are doing it with CCS. PeeCeeBee will remain free of CCS, as always. 🙂

I did a day long listening of the V2. Easy as it was to set it up within a couple minutes of powering up, its sound is just as effortless. A 250W amp with Big vocals, clean highs and tight bass. That's it! 🙂
I know your stand on CCS hehe..
I am now excited to build a version of the double barrel VSSA. 🙂
But it will have to wait until the wedding hehe
Thanks Shaan.

Thanks for all the support. 🙂
One more info, the V2 is real silent. With only 15000uF per rail at +/-56V linear supply there is absolutely no noise/hum audible. As thimios pointed, the split ground pays well.

Sorry I am too lazy to back read, hehe. I think I miss that part where thimios pointed the split ground.
How would you do that? 😀
Which PeeCeeBee? Can hardly see the boards. 🙁
Solid DIY job btw!!!
p.s. Yes a separate wire from input+feedback to PSU ground.

Thanks Shaan,
The circuit is from the first post but a different track layout.. 😀
Unfortunately I lost the file. 🙁
I have finished this late last year and had a busy work, this time back to the DiyAudio community.
That's why it is a late upload. 🙂

Well,
Its clean.. very transparent to the music it plays.
the vocals.. clear
I've noticed that this amp loves the percussion
No fatigue on hours of listening, you seems to want more
When you play a live band recording.. its like you are near the band.
