    Amplifier - bad sound when loud sound on bass
    by eduaqa
    I'n trying to fix a M&S SYSTEM DMC-1which have following problem:
    I'm using FM station to do this fix, I works perfect if volume below around 8 or if bass is set to zero, the sound can go to 20 without problem, but if I set bass to maximum and try to go over 10 the sound comes distorted ... I saw a video on YouTube the person saying about the main capacitors on the power portion, but I disconnect the main transformer and inject direct to the capacitors PINs my bench power supply -23v 0v +23v, but still distorted so I think the problem is not the capacitor neither the transformer...

    Telefunken L70 speakers, one has a nasal sound with less bass
    by Zonzi
    Hi everyone !


    Once again I have an issue with old stuff I found for cheap, guess I have a taste for these.


    I bought these two Telefunken L70 speakers for 20€ (https://www.radiomuseum.org/r/telefu...r_box_l_2.html), and they are in a superb state, component-wise. The box is scratched but I couldn't care less, I'm interested by whether it works or not.

    They do work, and have a really nice sound, but one of the two has a problem with its 8" woofer. It's got practically no bass, and the mids are really pushed...
