Thanks Brad, unfortunately i do not have the necessary skills or equipment to investigate the circuitry or establish the voltages and specification of an external supply so will buy the components indicated and give it a go and hope there are no bangs. Although these components are inexpensive...
Cannot see any printing on the board that relates to voltage levels, the caps have various voltages from 10 to275v,
was there a particular one I should look at?
when you say output devices are you referring to the speakers, if so how can these be tested?
Hi, thank you for the reply, here is a link to the circuit diagram which someone posted in a previous thread which may answer your question on which part of the circuit the triac is in.
**broken link removed**
I would not know where to start with an external power supply as the board has two...
I am trying to fix a fault on my Zeppelin air power supply which has blown a fuse and visibly a couple of components, namely one of the mosfets (T3), and an R500 resistor (R31).
initially I was just going to replace the fuse, resisitor, and both the mosfets T2 and T3 and see what happens but I...
