Now I’ve replaced the capacitors in another one very similar, a DE LUXE. It’s not quite as complete and in as good a shape as the Encore.<\/p>

What surprised me was that some of the electrolytic capacitors were bad (measured open) and the symptom was no sound whatsoever – not even a click when turned on – as if the speaker wasn’t connected. After replacing the capacitors, everything was normal. 🤔🤔  I could see this happening if the speaker was driven by an OTL pair with an open coupling capacitor.  But this is a regular push-pull transformer output stage.  <\/p>

Thanks, Joe Haupt
