The famous names made the magazine covers, but these filled real living rooms. Fourteen amplifiers, each with what it is worth today and the one thing to check. You will learn why number one is two amplifiers, since the Dynaco Stereo 70 sold by some estimates close to half a million by 1977 and the NAD 3020 sold well over a million while delivering roughly double its rating on short peaks, why the McIntosh MC275 is the one worth four figures and then some, and how the Sansui AU-717 earns the personal pick, as long as the corrosive factory glue has been removed. The video covers the Heathkit AA-100, the Fisher X-100 and its original iron, the Pioneer SA-9500 voltage check, the Carver M400 at two hundred one watts, the Crown DC-300A, the Phase Linear 700 nicknamed Flame Linear, the Kenwood KA-7100 sleeper, the Yamaha CA-1000 Class A switch, the Hafler DH-220, the Adcom GFA-555, the Marantz 1060 and its walnut cabinet, and the NAD benign error. Vintage Watts breaks down the vintage hi-fi market so you can listen smarter and buy with confidence. #VintageAmplifiers #hifi #vintageaudio #vintagehifi Chapters and key moments: 00:00 Fourteen amplifiers, is yours on the list 00:09 Heathkit AA-100, the amp you built yourself 00:49 The iron is where the money is 01:00 Check who built it 01:31 Fisher X-100, the tube amp that looked the part 02:08 Original iron or just an old amplifier 03:35 Pioneer SA-9500, the Silver Face tank 04:14 The voltage check on Japanese imports 04:59 Carver M400, two hundred watts in one hand 05:32 Figure out who will service it 06:10 Crown DC-300A, honest muscle 06:58 The fuse advice from Stereophile 07:26 Phase Linear 700, the amp nicknamed Flame Linear 08:12 Why the nickname stuck 08:29 Which version, and who serviced it 08:56 Kenwood KA-7100, the sleeper that measured best 09:33 The stepped attenuator and the relay 10:28 Yamaha CA-1000 and the Class A switch 11:20 The micro switches that fail 11:53 Hafler DH-220, the next Stereo 70 12:45 The rare Hitachi MOSFETs 13:18 Adcom GFA-555, the giant killer 14:04 Mark I or Mark II, and the fuse warning 14:37 Sansui AU-717, the enthusiast's darling 15:19 The corrosive glue question 15:40 Measure the fuse resistors, do not assume 16:06 Marantz 1060, the one that was everywhere 16:53 The walnut cabinet worth hunting down 17:31 McIntosh MC275, the real money 18:30 Original or reissue, and the transformers 19:02 Number one is two amplifiers 19:17 Dynaco Stereo 70, the poor man's McIntosh 20:09 Check the output transformers 20:20 NAD 3020 and the benign error 21:23 Which version you have 21:44 My pick, and what this list really shows Contact: vintagewattscontact@gmail.com Social media: https://www.skool.com/vintagewatts/about Facebook:   / vintagewatts   Instagram:   / vintage_watts   TikTok:   / vintagewatts   Pinterest:   / vintagewatts   X: https://x.com/vintagewatts Medium:   / vintagewatts   Disclaimer: The content on Vintage Watts is for educational and informational purposes only and is not financial, investment, purchasing, or professional advice.
