Seeking a schematic of the IG02580 chip used in the CR-3020

Hello, could anybody tell me what is the main difference between Yamaha AX-500 and AX-530? They both looks the same, the weight is almost the same and technical data look the same too.... There is even AX-630, which is almost the same, but there is added Yamaha YST slot. Thanx in advance. Michal

I recall somewhere i saw a statement that Yamaha incorporated a C2 into a integrated amp. Anyone know of this?

Hi group, I have a nice Yamaha C-70 preamp, in good condition, that has a cover with some scratches. I've wanted to get the top redone in a nice black powder coat. Have any of you used someone who does a good job with that? I'd be interested in sending them the cover and have it done. Thanks in...

I have a need for a 6 gang stepped volume/balance attenuator. 2 gangs are 53.38K and 2 gangs are 3K and 2 gangs are Balance 5KMN Ideas on how I may achieve this?

I guess I need some help with this. I have a YAMAHA AX-870 on the bench whose right channel was significantly quieter than the left. I have traced the fault back to a defective right-channel op-amp on the volume control board (NJM2068SD). As the component is rare, a Chinese import was the only...

Hello, The pot for the 'treble' knob doesn't seem to work. I tried spraying it with deoxit but it didn't have any effect. When I move the knob I can't hear any effect or even a crackling sound. My question is whether anyone knows the exact parameters of this potentiometer, the model or has a...

Greetings! Long time reader, short-time lurker, first-time caller. I have had a CX-600(R)for about 30 years, fronting a Kenwood Basic M1D. In the nineties to early oughts they drove a pair of floorstanding Infinitys from their low-sumer line that sounded just okay but could fill a sizeable...

After reading several threads about the Yamaha V-fet amplifiers I decided to get some myself. Always an exclusively Sansui man, I can still appreciate the efforts of other manufacturers in the late '70s. So this week two Yamaha B-3s arrived from Japan. And they did not disappoint! Great build...

I picked up a Yamaha YP-B4 at aution this summer and just got around to looking at it. Besides needing a new belt and cartridge, the START/CUT buttons were messed up, and the tonearm made a very unpleasnt grinding kinda noise when it was being moved by the start mechanism. I got all of that...

Hi All I Need Help have a Yamaha RX-V90 That lost sound on right channel started a service on it I found swollen main filter caps and scratchy controls I replaced all the caps on the main and standby power board with Cemi con from Digikey USA, also cleaned all controls with deoxit when I was...

Greetings! I picked this amp up cheap, however it was sitting in a storage unit in the hot Phoenix, AZ weather for "at least 10 years". The amped worked though and sounded pretty good considering. I decided to restore the old girl and bring her back to her former glory. I did this in steps...

Friends, I'm pleased to share this post with you all in what I hope fellow enthusiasts will find productive and useful. As the title suggests, included in this post are a set of cutsheets my girlfriend's father prepared for the content of this post: An as-correct-as-possible reproduction of...

Hello folks, my yamaha cr-820 had shorted output transistors on the left channel, due to a broken piece of plastic allowing a short to the heatsink. I fixed that by replacing both of the left channel transistors and now the 68ohm fusible resistor doesnt burn up on me anymore. But neither does...

Does anyone have experience with Yamaha’s Musicast system? I love the sound signature of my vintage Yamaha receiver and I read mixed but mostly positive reviews about their newer, higher-end receivers and integrated amps. I’m trying to build a system with analog, wired speakers and remote...

Hey folks, could someone with a VinylEngine.com account kindly share the service manual for the Yamaha YP-400 with me? I really wish I could access the PDF manuals on VinylEngine. Unfortunately, every time I try, it tells me I need an account, and it won’t let me create one...

This is not a request for belt flipping advice - not that issue. :) Since I have had this turntable, it never cued automatically and never had multiple advancement speeds in tonearm movement. I didn't care, I just used it manually and loved it. My issue is the tonearm moves to the right...

I picked up 2 Yamaha CR620 amplifiers a while ago, one worked and the other one the relay did not click. As an inexperienced noob, I accidentally swapped a transistor between the two amps after testing that one of the transistors were faulty. I ended up breaking 2 of the transistor because I...

Hello! I recently acquired this amplifier and there is an issue with the volume knob. When I turn the volume up and down there is a loud clicking noise that only goes through the left channel. I tested it on speaker B and the same thing happens. The right channel is fine on A and B. Its as if DC...

Hello Audiokarma friends. My Yamaha C4 has suddenly stopped outputting a signal through the right channel to my Yamaha P-2200 ( no signal whatsoever whether on Aux or Phono, and have tested the power amp with my DAC directly connected and both power amp channels worked fine.) Unfortunately I’m...

I recently acquired a Yamaha CR2020 and the am ferrite bar antenna is broken. I'm new to the forum and to this world, but really want to listen again in the way I used to when I was younger, to vinyl etc., and the radio. Questions 1. I looked on eBay, there are no replacement Yamaha antenna...

I've recently befriended a very old gentleman who has collected various electronics for what seems like half a century. He wants to sell some of his stuff and I'm interested in an M-80 amp as well as a Pioneer VSX-D1S. The obvious answer seems to be go ahead and pair the M-80 with my C-80 but I...

Hello everyone I have a pair of Yamaha NS-690 I, they have a decoloration in the shape of the front dust cover, I thought it was somethig related with the age and exposition to the light but I've been checking the same speakers on ebay and noticed they have the same issue than mine, does...

This thing is beastly! And gorgeous. Seller says that last he checked a few weeks ago it was fully functional (and I believe him). He bought off reverb around 2019 so hasn't been serviced at least since then. Has been serviced at some point because the VU meter lights are green (yuck) and the...

I have just bought a Yamaha RX-V870 amp and the left channel is very much quieter than the right. This is my first proper system (I’ve only had mini systems before) could I be doing something wrong or is there a problem with the amp and I should try to get a refund? I will add a video below
