Hello fellow AKers, I was recently given the challenge to resurrect or at least diagnose what’s wrong with a Yamaha A-S2100 that’s stuck in protection. With the diag key command, it will enter limp mode and presents three flashes. According to the service manual, this indicates an abnormal...

Just checking with the larger community here... picked up and repaired a Yamaha TC-511S cassette deck (recapped the power board and changed the belts), and all functions are working (specifically F.FWD and REW), and it plays well. One issue I'm having is that the unit has trouble with longer...

Does anyone have service manual for Yamaha P-28 turntable? Google points to VE, but I can't get it from there, as I am not registered VE user. I need to resolve a problem with the stop button and wanted to consult the manual before disassembly. Otherwise I will open the device and inspect what...

Recently bought a CA-1000 off EBay. Listing stated: The unit has been repaired and serviced, and it is in good working condition with clear sound output. The block capacitors, deteriorated transistors, electrolytic capacitors, resistors, and lamps have been replaced. The switches and volume...

Hello Everyone, I purchased my RX-495 back in 1997. It has been flawless until 2024 when it would suddenly "click" and turn off, either at low or high volume. It is sensitive to vibration. Something as little as putting my coffee cup on the desk can trigger it to turn off. Sometimes the...

Hi all, hoping someone with A-550 experience can help me diagnose a left channel issue. I purchased a a A-550 off of FB marketplace relatively recently. The amp has been working fine, but recently the left channel volume dropped to about 10% of what it should be. Right channel is perfectly...

Hello Yamaha enthusiasts! I am in the process of repairing a Yamaha CA-2010 that I purchased DOA, upon inspection one of the filter caps had exploded, I proceeded with a full recap, clean up, new VD1212 diodes and all new transistors and diodes in the power supply, powering it up with a variac...

Hi there, I replaced all of the bulbs and they were working for a bit but now the whole left side seems to have gone out. It is a lose connection somewhere but I can't figure out where. Anyone know where I should look to find the loose connection? Any help would be greatly appreciated!!!

Hi, I'm trying to figure out what can cause the -85V supply to drop to -60V when the bias increases up to around 40mV. With no bias, I get the +85V and -85V voltages correct. Adjusting the bias on either channel makes the -85V drop down to -60V. I checked the transistors on the negative rail...

Hi, I'm fairly new to hifi, so apologies if this is rambly/unclear. My setup: - Polk SDA CRS+ - NAD 7155 or Yamaha RX-385 - Sony PS-2000 w/ Sony VC-8E - MacBook Pro M4 or JVC XL-V282 for digital My first amp was the Yamaha RX-385. I would describe the sound as clean, clear, but lacking...

Hi! For a loooong time I had a turntable now but no real amp to pair it with. My dad had a very old Samsung (Smasnug as I like to call it) compact hifi thing wich had an aux in wich I used to amplify the signal from my turntable (with a cheap phono between the two). To finally end this age of...

Have any current/previous owners of the Yamaha GT-2000 (or later ‘L’ and ‘X’ variants) ever mounted the 64s on it? This is a combo I’m interested in for my rig but wanted to know how easy/difficult the setup would be. Would it require an external base, arm elevation and spacers? Is there anyone...

Hello all I am new to fixing audio equipment and I have this c80 I just purchased for 200. So back story I just deoxit all switches and controls and everything went smooth it played and sounded great. The rear rca for the main pre out was slightly temperamental if you touched the rca cables so...

Hi all! I have a Yamaha R-900 that is not working. When plugged in and turned on, it starts burning a resistor (or more) on the left channel right in front of the STK Module. I am aware that the STK Modules are prone to failure and all of the issues that go with it. This unit uses the STK...

I have a Yamaha CR-820 receiver and looking for vintage Yamaha speakers with the dark teak veneer finish, even a vinyl finish. I believe the NS-35T exist in this dark color. Seems to be rare and I can't find any documentation on that dark finish to match the CR series receivers. Anyone have...

Hi everyone, I recently picked up a Yamaha CR-800 for $150 as a non-working unit. When I opened it up, I found two blown fuses. After replacing them and testing with a dim bulb tester, I discovered one of the output transistors was shorted. I decided to replace all four outputs with new ON...

Trying to find an IC for my Yamaha receiver. Anybody know any resources that might have them? The only ones I can find are in China.

Picked up a very cheap M-35 because it has volume controls. Therefore, I can hook a source directly to it and have variable output. So I thought, this Yamaha GE-40 EQ matches well, is there a way to hook it up? I’ve tried a few different combos basically trying to hook it in line with the...

Hey all! Ive been facing an issue with my audio system for the past while and I really can’t think of a solution/what exactly is causing my issue. I’m running a pair of Yamaha HS8W speakers through a Focusrite 4i4 My problem is that the bass on some songs sound super muddy, and others not so...

hi all first post here so please dont judge :) So im trying to convert a motherboard failed yamaha avr to a power amp just by using its transformer, amp boards and speaker terminal board ?( dont know the name of this board) all advise comes in handy . First question can i connect line in signal...

I got this YAMAHA R-V905 but it is not producing any sound, I can hear very little sound in headphone out at full volume but no sound in A-B speaker out. Where should I start ? Thanks

The two bulbs in the FM quality windows went out and I'd like to replace them. (FM radio has been shut off in my country, but I'm using the CT-710 as a decorative piece now) This is my beauty the bulbs in question: 4mm in diameter, fitting straight into those rubber rings above...

I recently rescued a Yamaha KX-W900 dual cassette deck from being sent to the big landfill in the sky. What a lovely machine. The reason it was about to be destroyed was that deck "A" would not play and had a stuck tape inside it. Removing the front panel and looking at the mechanism from below...

Saw this champagne gold & rosewood DSP-A1 on ShopGoodwill and immediately thought someone here would appreciate it. It's pickup-only in Las Vegas (why I can't get it myself) - but surely some AK'er with a fondness for really good stereo amps (or crazy bargains) lives near Vegas. No connection...

Reclaimed a Yamaha C-80, as I sold the first one without really understanding the potential of inverted pre out. Not a bad price, but not one that I'm singing into the hills on. Anyway, seller stipulated public meet-up. Fine by me! Only how to test? I brought over-ear headphones, RCA-to-3.5mm...
