Well actually, a long, long, long, time ago, I read somewhere that David Berning did a design for a tube based Dolby B for his own personal use (never offered as a product). I've never seen any other mention of it, That would point to actual confirmation of its existence. IF it really existed I guess we could try doing a collective Group Beg & Grovel of David on the very off-chance that a) it existed; b) he still has the design; c) he would be crazy enough to want to share it and suffer the endless questions that could engender; d) he has time these days, as he appears to be offering fewer and fewer products these days, suggesting he has found better ways to earn a living; e) any of us would have the skills and/or the time to fabricate such a design (BIG HUGE ASSUMPTION GUYS). Still, if anyone knows David, as he does seem to be a really great guy and clearly an exceptional design engineer (who loves bicycles too). Or anyone live nearby in MD? I'm too chicken, I think we should leave him alone. Well, maybe ONE phone call, by ONE of us?

While I've always been curious as to the above, honestly my gut tells me that the best genuine real avenue approach in-the-here-and-now to explore, is to try modding the Advent 100 Dolby B. Why? Because it's all discrete devices with relatively simple circuit topography. Some basic standard mod approaches (pwr supply improvements and coupling & eq. cap upgrades) should easily provide some immediate improvements. Plus a couple of us appear to have one. Wether that would be enough to be worth it is the mystery.
I have a scan of the 100A schematic if anyone can guide me as to how I insert it here. (Or even wants it)
