Just resurrecting this nice thread Sharing this review / objective measured performance of the Denon PM-90.By today's state of the art, said vintage gear can still stand toe-to-toe!https://www.audiosciencereview.com/forum/index.php?threads/marantz-pm-90-review-vintage-amplifier.26724/
^ang suggestion ko pag ganyan, at lest 24 hours straight na nakapower on lang, zero volume...
hindi ba delikado sir? sabagay hindi naman siguro mag iinit masyado kasi hindi naman sa tumutunog....thanks sir
depende sa amp, class A amps kahit walang sound umiinit
Meron pa kayang bilihan ng surplus amps? Saan lugar kaya meron? Baka meron kayong mga updates dyan.
Sa pier, halos wala na, if meron, yung mga di magandang brand. Check FB marketplace, maraming sellers doon....
Last time I've checked beginning of the pandemic wala na sir. Sa mga probinsiya meron pa like a 1950's heathkit mono amp na nakuha ko sa Ilocos Sur
I have a PM90, natengga ng 3++ years, yesterday sept 29,, sinet-up ko sya, ampangit na ng sound, parang muffled sya, I tried on 2 sets of speakers, Sansui LM330 and mission MX5...pareho ang tunog...I will try cleaning baka sakaling umayos pa ang tunog nya...sayang pag nagkataon, ganda pala ng review
