Thanks! Have you updated the lights on the CA-1010's to Leds?

Not recently. Plenty of threads here to aid you. If you choose to do so.

I’ve done it in mine. You need to rectify the AC from the power board, add a smoothening cap between the rectified + and - and add a resistor of the correct value in series with each LED. You can't put all 5 LED's in series with one resistor, because 5x voltage drop is more than the rectified DC.

Mr. Yamaha I read your post about the CA-2010...great pics great work...how did you get the boards so clean?...mine still have flux from the manufacturing process all over

So I ordered some trim-pots not sure if they are the right kind. http://canada.newark.com/bourns/338...22lf&ddkey=http:en-CA/Element14_Canada/search

Hoping the Yamaha experts are reading today. Recently acquired a R-2000. Very powerful clean power. I'm pleased. One issue... Ugly hum from the phono section. Even without a table plugged in. Before I open the hood. Any idea??

What I think is you need to start your own thread This is someone else's thread about a completely different amp

Flux cleaner, dish wash soap and an oven at 50 degrees celcius are your greatest friends

Hmm, I do like the multi turns better. These are single turn. But, they should be able to do the job just fine. Maybe a bit more touchy to adjust.

General question. I suppose I should

For the LED couldn't you just do a single wave rectifier on the 12vac?
