Удивляюсь, в хорошем смысле, двум вещам: Людям которые это изобрели и чуваку который даёт технике вторую жизнь! От куда он всё это знает, что и как должно работать! Уважение таким мастерам!!!

I love how there's a front sticker with 1500W PMPO while the actual amplifier is a 2x 70W and likely even shared among 4 speakers. Good old 90's.

It was less than that, if you see how they count. However, sensitive speakers meant 105db (measured) from this system. AIWA had their own, it measured less than 2x30 watts, maybe even half and they advertised it like 2x100. And it still went up to 105db with their own speakers. Lived it firsthand. 105db and it had bass still thumping...Amazing for what it was.

its not, its 100 Watt RMS per channel as per service manual.

@@Shamsithaca It is way less than that. They announce 100 watt RMS per channel if you accept great distortion in the signal and for 1khz signal only. If you measure for two channels, 20hz-20khz and for less than 1% distortion it may even be 15-30 watts per channel tops. Which is still pretty good. IF the speakers are somewhat sensitive, it will get loud. It will need around 30ish watt to hit 100-103 db. If you ...ok not many people care about harmonic distortion, just volume so yeah it will get louder and louder and it has an active preamp as well so that helps too. It can outmatch smaller "hi-fi" systems in a party. Aiwa's systems did too.

@@81giorikas I think you are highly underestimating the competition between SONY, AWIA and Pioneer, also a bit from Panasonic between 1994-1999. This particular model was sold as RX90 in Europe and (for the dolby system100 RX in N.American markets, as the GR8 in Asia (not sure if this was ever sold in Japan however). There is no way on Earth they would be selling these with incorrect specs in their manuals and service manuals and ads as 100 watt RMS per channel, 20-25 watts RMS for the surrounds. There is not a single case of consumer fraud against these brands, nor any recorded sues over that period from consumers for these hifi systems. THD was correctly stated, as was distortion. if you are simply referring to bass distortion alone, at high volumes, SONY had the ingenious system of VACS (Variable attenuation control system) chips (you can find clips of it working on you tube with proper scientific, spectrographic analysis). Pioneer had edgeless woofers with 30-35 mm lateral excursion that was developed by the TAD scientists. The competition was fierce and so were the products that came out during that era. If you were testing and analyzing the sound data yourself there is without shadow of a doubt using a faulty amplifier, or malfunctioning system, speakers etc. If you want a sample size, try it the scientific way and get a few unopened box RX90 or those that were kept in pristine condition. the STKS can deteriorate from decades of use. I recently got an unopened MHC 3600 Made in Japan (1993), the sound was divine, you cant get that these days.

Я тоже свою разобрал. Отремонтировал подкассетники. Заменил тактовые кнопки, пасики. Поменял смазку. Вымыл всё от пвли. Ничего страшного в ремонте не оказалось. Энкодер тоже почистил и он за работал как надо. Шестерни там еще лопаются на моторе выбора режимов.

Thanks for showing me I'll have to replace all the buttons 😅 but at least the potentiometer fix is quick 😊 Great video and it will be very useful for me to fix mine. I have been postponing it but now that I've seen the process I might do it soon 😊 Only difference is I know I'll have to replace some tape section parts bc I know they're broken.

Bende 2 eski model entegre amfi var (Pioneer ve Rotel) İkisinde de separasyon sorunu var. Ses tek kanaldan geliyor. Bazen sağ hoparlorden bazen sol. Açıp kanal düğmesinin arkasına contact cleaner sıktım, bir işe yaramadı. Sizce tamiri mümkün mü? Bunu gibi midi Sony Set var. CD çalar sürgüsü kapanmıyor. İtip yerine koyuyorum, ardından hemen geri çıkıyor. Tamiri mümkün müdür?
