PEECEEBEE V5 GB

...what is the maximum DC voltage allowed? +- 50V is the absolute maximum?
The amp can sustain higher voltages as all the transistors are at least 160V rated.
But we have PCB real-estate for only two pairs of the power trannies. Using higher voltages may put them on the border of their safe operating area in case load impedance takes a dip, unless more pairs are used.

So yes. For this amp I would say +/-50V is absolute max.

Can't wait any longer. I added HRDSTL also

Not in this one.
Three reasons.
No space. No space. No space.

Actually, unlike pure EF OPS this one's drivers can't be mounted on main HS due to it being CFP/sziklai. Two OPs are apparently the max load the driver can manage, and that with local small heatsinks which got pretty hot during sustained 100W sine into 5R (more on that coming in the setup guide).

Maybe in V6.

Arrrgh, Agonizing, so many amps, so many DAC's, so many pre's, so many speakers, so much to learn, and so little time to build as we age:ROFLMAO:. It's never about the money, always about the time. Will have to think about this one, as I need to build the V4H also. Shouldn't have to think to long;)

Sent from Mexico (winter get away).

I couldn't agree more. :) Too much fun to have and too little time!

Wait!

V5 has gone through a revision in the last couple days. 10KHz 50W harmonics (primarily h2 and h3) went down from -82dB to -92dB. :yes:

I am gathering spectrum data as I type. Will update the details in a few hours.

Thanks everyone for your interest. After the latest update I hope more people will be interested in the V5.
