primecujem znacajnu slicnost izmedju Leak TL/12 i Quad II pojacavaca
barm u napajanju i izlaznom stepenu donekle...
.
ono gde je razlika je ulazni stepen i obrtac faze a to je jako vazan deo PP apova uopste
kod quiada to radi perfektno
.
Za Quad II je navedeno da je to ultralinear koncept izlaznog stepena, dok kod Leak TL/12
za tu opciju postoji mogucnost ugradnjom jednostavnog preklopnika,
posto ako je kao sto je naznaceno na shemi,
OT ima izvode za UL mod...

Glavna razlika izmedju Quad i Leak designa se sastoji u vrsti povratne sprege na izlazu. Walker je izmislio novi tip tzv. katodne povratne sprege, koja ima dosta prednosti narocito u odnosu na klasicnu globalnu povratnu spregu kakvu koristi Leak. Taj izum Walkera je usao u istoriju a vrlo brzo su usledile i McIntosh i Audio Research varijacije na temu. To se sve desavalo tamo negde sredinom pedesetih proslog veka...
