    Newbie needs help fixing CV LS 10 crossovers

    I got a pair of Cerwin Vega LS10 speakers from a friend when he moved away. The tweeter on one speaker, however, has stopped working. I've checked the diaphragm and it doesn't seemed blown so my understanding is the next part to replace is the appropriate capacitor in the crossover. The...

    Just recapped a pair of Sansui SP2000 speakers

    I am sure this has been posted many times. But... I bought the speakers at a flea market a while back. I noticed they were buzzy playing some music off Youtube and the buzz was somewhat inconsistent. So, I bought the crossover capacitors and just replaced them all. $7.00 for the parts, $6.95...

    Schematic Tuner PS Capacitor Rating Different Than What Was Found

    Just wondering why on a service schematic a capacitor in the power supply section of a tuner is rated 1000uF/16 Volt and I found a 2200uF/16 Volt Cap in the unit. Somebody said thats what was probably handy on the day of manufacture. Safe to go with what's on the schematic?

    Need Suggestions for Capacitors

    I have a Kenwood KA-2500 Integrated Amp with some bulging capacitors and need some suggestions for replacements.

    Recommend a DC blocking cap?

    My preamp puts out just a tad too much DC and is setting off the DC protection in my amp. Only occasionally. Generally only when inductive or large loads are turned on in the house. Yep, I've tried different outlets and power conditioners, to no avail. The (tube) preamp maker tells me that I...

    Discharging capacitors that are soldered into place

    There are plenty of videos on YouTube showing how to discharge capacitors, but none of them (at least the ones that I have found) show how to discharge a capacitor that is soldered into place. Can anyone share the proper way to discharge a capacitor that has been soldered into place? Or is this...

    MARANTZ 2230 LOW FILTER SWITCH CAUSING LOUD POP

    Engaging/disengaging Low Filter switch causes loud popping noise through the speakers. Regardless of the position of the volume dial the popping noise is audible and unaffected by attenuation. I have verified that this is an isolated issue with the low filter switch and only the low filter...

    Can't find these components...

    So I've become sort of infatuated with old record consoles and portable record players and now have 5 project pieces; 2 Sears Silvertone portables and 3 consoles. I'm starting with what seems like the easiest (the smaller Silvertone) and would like to replace the 2 caps and transistor, but after...
