My nearly perfectly restored Yamaha A-1 still randomly cuts out! Power stays on and no fuse blown or magic smoke and amp runs relatively cool. All caps have been replaced. Brand new Omron speaker relay replaced. Offset, idling, all very stable and correct from the service manual. Most of the...

I'm working on a yamaha CR-1020. this is the first one of these i've ever opened up. but I have restored many sansui, marantz and HK units. i notice a light to medium buzz that increases with time from the phono input. another clue is the two small caps furthest to the right on the board, if i...

Hello all. The Yamaha A-1 has an aesthetically beautiful stereo volume knob. But, the flat disc section that controls the …. channel has worn lose in the centre. What’s the best cure? Blob of glue? Some substance to ‘pack’ the interior so that it’s a tighter fit? (Both of the above seem like...

Hi everyone a couple of weeks ago I got a Yamaha A-6a (Japan version of the A-760II) and it has no power! I opened it up and replaced all the capacitors on the main board, the B supply voltage was only 1.4v all the voltage readings coming off of the power supply board are fine. Except the...

This is the rear RCA Panel for a CA-1000, I would like to upgrade the RCA connectors to Gold. I am seeking ideas for custom PCB design to accommodate this.

Hello.. Does anyone have a list (BOM?) for replacement of capacitor types ('low ESR,' or 'good for power supply' designations is what I'm really after) on the Yamaha C-4’s main board? (The ‘Function C Board NA 07149.’) Could probably buy all Nichicon FG or Panasonic FC but would be grateful...

Hi, Can anyone shed some light or have an opinion on the quality of the DAC within this machine, the Yamaha CDR-HD1300? I presume that since the machine offered very high quality HDD analogue recording from CDs that it would have employed some very good Yamaha electronics. But rather than...

Hi all, I'm having a bit of a problem with a YP-D4 direct drive turntable from Yamaha. Though I set it up like in the service manual the speed wobbles a bit, it is more obvious on the strobe that moves bit left and right. I've also made a speed test with an app, maybe someone could give an...

I know that there is some worry that sound wave diffraction from the edges of drivers can be of concern. To reduce that on my NS-1000's I cut some wool panels to place over the mid and high drivers. The material is 1/2" natural wool felt and I have attached the laser cut file here if anyone...

Hello. I have the NS-1000M (90dB) and the FX-3 (92dB). I assume that with the same amp at the same volume settings position of the knob, the volume of the FX-3 should be higher due to higher sensitivity. This doesn't happen with my speakers. The NS-1000M play slightly louder than the FX-3 at...

Just got a Yamaha CA 810 off of eBay. It's visually beautiful, nicely cleaned up by the seller. However, even with the volume all the way down, and the tuner not selected, despite there being no tuner attached anyway, I can hear the radio. It's pretty unsettling. It doesn't matter what input or...

Hello! I've recently recapped my m70 and changed trimpots and some other parts. I was going to adjust everything today and things worked out great but wen I was setting the meter lights i encountered a problem. I used a 8ohm 300w resistor as a load starting with the right chanel, I'm putting in...

Hi all, I feel kind of silly asking this but where comparing pictures the amp output assemblies and parts look identical. I have not been able to compare parts lists for these two and thought I would ask since a lot of parts are interchangeable on these.

Hello all, just finished a rather lengthy restoration on an M-2 and wanted to document the process. This unit was quite easy to work on due to excellent service information and disassembly procedures in the service manual; Strongly recommend following Yamaha's instructions for disassembly. I've...

Gentlemen, knowing that certain receivers match better with certain speakers and that notation aside, to whom would you give the nod either through experience with some or all of these speakers in each group OR what you have ascertained over the years by rote memory Group A Fried Beta V Mirage...

Hello guys, Want to get a new amp, would you help me understanding the difference between this two models? Difference between A-S801 and R-N803 Thank you guys!

Yamaha Squad - Here's the story: CR-620 powers up with lights on, no sound, no relay click Replaced C816, no change Replaced TR809 with KSA1013, no change Replaced TR808 with KSC1845, now relay is clicking immediately (I'm used to waiting a couple seconds before these engage but this one now...

I bought a discounted Yamaha TC-520 cassette deck from Ebay. It has a bent Stop/Eject button. Can this button be detached independently and replaced? Appreciate any leads you can steer me to.

I have an old Yamaha P2250 having protection issue, after long troubleshooting, I found that there are DC voltages coming out from PA(A) output TP205 Base +/- 23 vDC and Emmitor +/- 23 vDC Protection mode turned off when I disconnect +/- 15v that power up OP AMP or remove output jack from...

Hello Audiokarma folks! I hope that someone here has owned or still owns Falcon Acoustics Q7 or Ascend Acoustics Sierra 2EX speakers and can share their thoughts on those speakers and how they compare to each other, strengths and weaknesses, etc. I currently have 2 integrated amps and 3 sets of...

I'm looking to replace a cheap amp I'm currently using for my setup. From my research, I've narrowed it down to the Denon PMA-600NE and the Yamaha A-S501. Out of these two, it seems the Yamaha would be the better choice. However, I've just recently acquired a Rotel RB-850 for $15 dollars, and it...

Issue: At start up the relay would click on and off sporadically without any manipulation Troubleshooting Steps: Checked to see if pressing on/manipulating the protect circuit relay would help, it did not Checked voltage at TR-801 and got roughly 57V DC on ECB. In different, similar thread, I...

Hello everyone. I sold a bass guitar to this guy and he offered me "an old hi-fi amp" for free. I was reluctant to take someone's rubbish at first, until I saw it. It turns out it's a Yamaha CA-810 and in almost perfect condition. It all works and sounds fantastic, but the only thing missing...

My P200 has started crackling when I first turn it on. After a while it stops making noise and sounds clean for hours. I think this must be a capacitor, possibly in the signal path. Has anyone seen this symptom before? Any ideas that can point me in the right direction to repair it? I'm not...
