Hi, all.

Can someone help me with a clear scan of the KEF Celeste IV (SP1108) circuit diagram (.pdf file), please? Willing to pay reasonable sum via PayPal if necessary.

Many TX.

I saw a couple of crossover boards sold on ebay. It appears to be a pretty simple and straightforward crossover that you can trace even from the PCB.

Is it the values of the inductors that you really need? If so, you need access to one of these and an inductor/capacitance meter.

Unfortunately I don't have any SP1108 available so can't help with tracing and measurements.

I can't see anyone having this somehow.

If this is super important to you and you're willing to be without the crossovers for a while, PM me to arrange a way for me to trace the circuit and measure components (all in the interests of increasing the knowledge base).

Many thanks, SaSi. The original caps were replaced some years ago so I just wanted to confirm the original MFD and voltage values.

Many thanks for your kind offer, Speakerguru. As explained earlier, I just need to confirm the MFD and voltage values of the original capacitors. While I am at it, I want to change the spring-loaded speaker cable input terminals. If anybody did this and has any recommendations, I would be very grateful.
