So, we know a new BeePre is coming. What else do we know? Only this much:
A universal power transformer is indeed part of what's up.
Note the phrase "
part of what's up". So there's more. So let's speculate what it'll be!
In the thread from which PB's above quote is taken, someone expressed hope that the filament regulator will be immune to mains voltage sag -- b/c when the reg drops out you get a lot of hum/buzz. I think the new universal power trafo with different primary winding configurations will take care of this in most cases -- but perhaps the voltage of the LV secondary will get bumped a bit? And maybe permit a bit of smoothing before being sent to the reg? I doubt this last bit b/c that would be overkill (which, of course, is why I included a CLC filter before the fil reg in my Beepre rebuild
)
My biggest question is whether the attenuator will be moved from the input to the output to increase SNR, as in the Moreplay. If yes, I really hope there's a mod to make this work with existing Beepre's. IIRC, PB mentioned in another thread in the last year that to do this other circuit changes are needed to maintain the output impedance of the amp. I'm not sure if moving the attentuator would make much difference for those who keep the Beepre attentuators turned up pretty high -- but I'm guerssing it might make an audible difference for those who only use the first two (highest dB reduction) positions of the coarse attenuator.
What else? Let the wild guessing begin!
cheers, Derek
