    Installing Crossover for Pioneer S-HF21-LR

    I'll put my question up front and backstory is below the schematic. Do you think I'd get an improvement if I were to install a proper crossover into all eight of these speakers? (not really asking about is it "worth it" since I think I know the answer to that based on the cost and labor) There...

    Hello all, I’m exploring a possible repair on a Pioneer SA-1490 receiver I got from a friend who insists it was working for him before giving to me. I’d like to save it from the recycle pile but it’s not working now. Two sentences about me. Although trained as a EE, I’ve leaned on more of the...

    Requesting guidance on Systemdek IIX restoration

    I recently was able to buy a Sytemdek IIX that appears to be an early model (steel bottom, teardrop armboard). When the power switch was clicked on nothing would happen. I researched a bit and thought it would be the capacitor but ultimately turned out to be the switch that was faulty. I've...

    Leaking cap or glue?

    What I find odd is why would only 2 caps be glued. Glue is typically clear or tan. But look at the bumps of crud around the one picture. Seems odd to glue these down since 1 is 6.3V and the other is 35V.

    Electro-Voice 1182 capacitor confusion

    A neighbor gave me an electro voice 1182 a few years back. Right channel works, however left channel is very faint. I’ve identified the problem as a damaged, leaking 50mfd cap in the power amplifier board. This brings me down to the question, is mfd the same as uF? If not, please let me know the...

    Help ID'ing Capacitors in Beomaster 3000-2 (2402)?

    I am pretty sure these are tantalum capacitors ... but this is my first rodeo with caps in this packaging with this coloring so I wanted to make sure. They are not marked with either values or polarity. (I can find both via the schematic, but that's not my question here.) (I replaced little...

    Sonicap Capacitor Cost

    Why have Sonicap capacitors gone up in price? I'm not talking double, but about 5x the cost of what they used to be a couple of years ago. Just puzzled by the price increase. Is there any places other thank sonicaft, they can be purchased from?
