I need help identifying these speakers, they were on my grandpas basement since a long time ago, they work fantastically well but I don’t know the make or what kind of speakers these are. Also, if you have any suggestions for the two speakers missing on them would be much help. Thanks btw! Daniel.

I got this amplifier a while ago and I noticed that the fuse on one of the channels was blown (I think it's the right one). I measured the output transistors and the ones for the defective channel where shorted. I ordered some new ones and installed them (for both channels since I read online...

Apologies if this has been covered already, I tried searching but it's a tricky query. I've been looking at some older / vintage Yamaha amps from Japan, which are 100V / 50-60 Hz. I live in the US, so I understand that to power them here I'd need a 120V > 100V stepdown transformer. Which...

I am currently working on a se-9200 power amp that really does not need that much work. I adjusted the dc offset on the speaker leads to 0.00 volts however I also wanted to adjust the bias but I couldn't really find anything about this in the service manual. I was expecting maybe a target...

See title. Is this normal ? And if not is it easy to solve? I would prefer keeping it as is as it was completely overhauled a few years ago. But since it's not mine I don't know if this has always been the case.

Hey all, I was able to procure a Diatone DS-2000HR set while serving overseas in Japan. I decided to put together some light reading on the subject, seeing as though it's a mostly unknown brand stateside. Inside can be found the original Diatone publicity release article, the speaker specs, an...

I am working on a yamaha p520 and it doesn't spin at all. Any clue what it could be ? I tried to measure the output of power transformer but I couldn't get any voltage reading. One other thing I noticed is that the strobe light doesn't turn off if the arm is in the off position but it does start...

Hi there, new to the forum, just starting to build up a new system and trying to decide on an amp and speakers at this point! Currently just picked up the preamp, Technics SU-9070, and looking at likely more Japanese components. Wondering if anyone could give me any pointers in terms of hooking...

I'm looking for replacement screws for my Japanese-made Philips 22AH180 tuner. These are self-tapping Phillips pan head screws with 2.9 mm diameter and 1.1 mm thread pitch. They are similar to #3 screws but have narrower thread pitch because they are intended for use in metal. The manual lists...

Hi Everyone, I have recently moved to Japan and wanted to put together a distinctly "Japanese" system. On the speakers side I am leaning towards the Yamaha NS-1000M. On the amp side, although I have been a solid state guy up until now, I have come across the Luxman MQ series tube amps and am...

When I first bought my Realistic SAF-40D integrated amp , I had thought maybe Trio-Kenwood had built my amp after looking through threads on here and other sites. Although Radio Shack kept their amp supplier a mystery, some compared the amp's topology to that of contemporary Kenwood amps. But...

Hi. I have a real passion about sound quality that has manifested itself into an SQ car project and also an SQ home cinema system project. My dad recently asked me if I could find him a nice CD player with the emphasis being sound quality and ideally from the timeline of 1980 - 1994. At the...

I recently picked up a Sansui 3000 from an Estate Sale and only the right side is functioning. I opened it up and wow is it gorgeous inside! It appears as if one of the 2 or 2.5 fuses keeps blowing. I replaced it and it worked for a moment and then blew again. Any ideas from those who are...

Bought this amp marked as an AEL CX-747 recently out of curiosity as much as anything and was pleased to find it actually runs in completely original condition, with surprising sound quality, despite being close to 50 years old... Further research into components and build suggests it's a high...

Hey all; I’m starting this thread to catolog the restoration of my SP-5500s. I just picked up 4 of these massive bad boys for $40 today. I’ll inspect them closer tomorrow or this weekend but right now it appears they’re in pretty good cosmetic shape. I just popped a grill cover off for the...

Hi, I'm about to purchase a Japanese SA-CD player which requires 100 volts. I don't want to belabor a topic that has been discussed a fair amount, but my question is fairly specific. Correct me if I'm wrong. A transformer is a fairly 'dumb' device that may not deliver the exact specified...

Last week, on my birthday, I found a really nice pair of vintage speakers. They have everything I like in a vintage speaker. Heavy real wood veneer cabinets, acoustic suspension, wood slat grills, and in very nice condition! Only problem was that one of them made a banging noice when I moved...

This Kenwood turntable has a story... but I can't make it work. About a year ago I was heading up north to see my family and attend a funeral, and I thought I'd check the local Craigslist to see what was for sale. Lo and behold, this Kenwood KD-500 with SME Series III shows up for $200. I reach...

Good evening folks! Its been a while since I have posted here. Very recently I acquired an Accuphase E-204 Integrated Amplifier. Cosmetically its in a very good shape but electronically its a bit of a mess. The unit switches on and plays audio but with certain conditions. Only when the TONE...

Please help. I just bought these 2 pieces: SANSUI amplifier A-E77D and SASUI EQualizer G-E77D and unfortunately it does't come with any instruction(S). Anyone have any ideas how to connect it together? I already checked and both pieces work ok, but I have no idea how to connect the equalizer to...
