    RT-701

    I'm recapping the servo amplifier. There are 4 Sanyo 25v 0.1uf electrolytics. Are 25v 0.1 uf multilayer Ceramic Caps an acceptable replacement? If not what would you suggest? Thanks.

    LEDs for lighting

    I've seen a number of posts regarding the use of LEDs as replacements for the old incandescent bulbs. Many times people are not satisfied with the color of the light or the dispersion. Both of these are subject to the individual's personal taste. On the color side, warm white will be a closer...

    PC5002M

    A while back I found a PC5002M for a fair price on the auction site. From the pictures, it was in great cosmetic condition, which was important to me. The seller strapped it to a pallet with the only protection being a piece of foam tapped to the face and shipped it via common carrier truck...

    Help Identify Parts

    These are parts from the meter driver board of a Yamaha PC2002M. On the schematic, they are listed as 10 ohm resistors. I can't say that I've seen resistors that look like this before. They look like capacitors to me. Both are toast, so I need to replace them, but want to make sure I use the...

    PC5002M

    Can't find VR301 on the board diagram. Should be on the driver board. Found an interesting arrow down towards the left-hand bottom between C303 and C304 and right above R317. Think that is it?

    PC2002M LED Conversion for Meter Lights

    I recently acquired a non-working PC2002M. One of the problems was the meter lights were all burned out. Rather than replacing them with regular light bulbs, I installed LEDS. It was relatively simple. The bulbs are feed with 12 v DC. I used a Linear Regulator to convert that to 3.3 v...

    Need Help with PC2002M

    I need some help trouble shooting a PC2002M. It won't come out of protection. Prior to this it was fine and took about 3 sec to come out of protection. So far, I found that it lost the +80 v DC. The-80 v DC is OK. All the fuses are OK. Thanks

    Using LED's for replacement lamps

    This topic comes up from time to time. Here are pictures of LED arrays I've used to replace incandescent lights in Pioneer equipment. In all cases, I've used "flat top" LED's. You can use any color you like, but the color will determine the dropping resistor value needed. "Warm White" is...

    SX 828 Need voltage reading from SM

    I have a service manual that's very hard to read. From what I can tell the voltage on pin 4 of the power supply should be 45v. Mine reads 4v. The question is am I reading the SM correctly. Should the voltage be 45v? If so, where should I look to correct the problem? The other voltages...

    I bought a SX 1250 from the auction site that wasn't quite as advertised. Imagine that. The unit had several blown fuses. Replaced the fuses and started it up with a DBT. Obvious short some where. After an inspection, the problem was missing insulators on Q1 and Q5 on the stabilizer...

    How is the protective screen on the 035 TiA tweeter removed and then replaced? I recently acquired two, but the screens are bent. They could be easily put back into shape if removed from the actual speaker. Thanks
