PPL and myself have been listening to the PPA proto on any 9-32 volt AC wall wart we could find without any audible problems. The battery board is simply for those people who enjoy good tunes at the park, mountain, relatives, etc.

I assure you a battery board is not needed but it will be a very nice accessory.

Ok, I don't think I'll need one. thanks!

Thanks Tangent. 30 to 40 hours of battery life in an awesome sounding amp that has the capability to be a transportable is totally awesome. That's all I wanted to hear. It wouldn't matter for some people to use the maximum amount of cells the board can take if they'd be travelling and want to bring the best sound they can grab on to.

Two thumbs up!!!

Fair disclosure: you'd have to go with AAs to get that kind of lifetime, or an external battery pack. Going with AAA's lets things lay out better inside the amp, and lets you get a higher supply voltage at the expense of run time. With a simple AAA battery setup inside the amp, lifetime is more like 7 to 15 hours.

still enough for a full days usage even with AAA batteries, awesome!

Any updates?

 

[tangent]

Soon, yes. Patience.

 

[Whitebread]

Sweet!

hey, is there space on the board for a shunt resistor after the pot so people could use a linear pot with potentially better tracking?? just a thought...

Hi Guzzler. Sorry, we are not going to add onboard shunt resistors. Shunting a linear pot presents a variable impedance to the source. The Alps Blue is a good pot. If you want better, use a stepped attenuator.

Sometime later today I will start a new thread to announce the PPA final candidate and issue a last call for comments, suggestions, and requests.
