Re: Sound improvement on LV1020: Capacitors a.o.

Tip 3. Speakers with no interconnect cable catch hum noise. Such noise is like a wire without a screen or ground. I accidentally found a problem, connect interconnect wire a signal immediately to the board from my DAC. Connectors DIN better than RCA, I soldered the wire directly to the connector on ...

Re: Sound improvement on LV1020: Capacitors a.o.

When I wrote that I would change the scheme today by connecting between the emitter of T605 and R615, at that moment I thought that it would change and improve the bass, because what I now have sounds like the ultimate dream. It turned out that I did not carefully read the text of the error only in ...

Then I bypass T501 T502 Sound from one speakers started sounding r...

Re: Sound improvement on LV1020: Capacitors a.o.

Hi Pashka, thank you for your tips. At first, I would like to draw attention to a bad mistake in the circuit diagram. Of course, the connection between the emitter of T605 and R615, bridging R618, must not exist. This is doubtless a drawing error, which was overlooked by the 'lector'. Heinrich than...

Cut off feedback to amp in LV1020

Tip 2 Improving the sound by 40% up, Тurning off the feedback in the LF . Take off one leg of resistor R614 on LF amplifier. 1.8 Kohm Feedback resistor is not worth on the other two amplifiers MF and HF. What does the feedback do? Sends the output back to the input of the amplifier. The sound is com...

Re: LV1020 Capacitors

Audio grade capacitor (Elna, Black Gate) sounds better than all over. Theses devices are designed for high end audio. They have particular internal structure, which seem to be very important for audio render. While, very low ESR doesn’t seem to be quality argument. Elna gives detail and pictures abo...

Re: Raschel-Geräusche auf LV720 Mitteltonkanal im Leerlauf

Ich spreche Deutsch nicht. Aber was ich verstanden habe, wird das Problem eines Rauschens des MT nicht behoben.

Das Mausrauschen im MT-Kalotte. wird wegen des schlechten Kontakts fues Halter geschaffen. Es ist für Lotbeine eines fues Halters notwendig.
