*Bei diesem Verstärker wären das die zwei 3300µF/63V Siebelkos inklusive der Spannungen, die Kontakte des STK-Hybriden und dessen Wärmeleitpaste.
 
*Die alte Leitpaste ist nach der langen Zeit kaum mehr als eine Kruste.
 
*Diese lässt sich mit Alkohol leicht entfernen und danach wieder dünn auftragen.
 
*Man sollte es wirklich dünn auftragen, da diese nur die Unebenheiten zwischen Bauteil und Kühlkörper überbrücken muss. 
 
** Gesamt ein gut klingender, kompakter Kleinverstärker, der bei Zimmerlautstärke immer noch seinen Dienst verrichten kann.

  • The small amplifier uses a STK4141II hybrid as power amplifier.
  • On my unit, one channel kept dropping out.
  • Because of this, the previous owner had probably already put a dent in the lid
  • After cleaning and re-soldering the circuit board the amplifier was intact again
  • It is advisable to check the old hifi equipment briefly before shouting at it, shaking it and banging on it
  • With this amplifier that would be the two 3300µF/63V screen electrolytic capacitors including the voltages, the contacts of the STK hybrid and its thermal paste.
  • The old conductive paste is after the long time hardly more than a crust
  • This can be easily removed with alcohol and then applied again thinly
  • One should apply it really thinly, since this must bridge only the unevenness between component and heat sink
    • Overall a good sounding, compact small amplifier that can still do its job at room volume
