Clark TK 24 Issue

Post by Ludwig von wigbearer »

Sounds like the audio amp has gone. There's a work around using a mini 5w external amp but it's a little fiddly. Alternatively you can return to Clark for repair. Details of how to do this are on the Clark web site.

Thank you Tom, There is a small resistor on the rear of the board (200 ohm) , I have tried bridging it without
any joy, being an older TK board I have used it with a 8ohm speaker and not at full volume, is the fault
a common problem, never had this with my other Clark boards.

:) Hello,
have you looked at the volume potentiometer? there was no unsoldered wire, or badly connected, or cut track?

the HP output impedance is 8 ohms, if on the other hand you use a 4 ohm speaker, there is a risk of destruction of the output stage? Also check that your HP works, on another device, for example !!! can the coil be cut?
