Default Ace Embassy 50

Hi all,

I have recently been given an Ace Embassy 50 radio. I can't find any specific service data for this set, but the chassis looks very similar to the circuit for the 357S or 3561S diagram that I purchased from Paul's site. The image "Model" shows the set details attached to the chassis.

I have removed the chassis to have a look at the condition of the components underneath. As a result I have a couple of questions, if anyone can help me please.

Firstly after removing the chassis, a black wire has parted company with its original connection point. It clearly wasn't well soldered, but I'm unsure where it connects, you can see it on the left in "Image 1". It appears to go to the on/off tone switch. It originates at a junction between UU12 valve and the 32+32+8uF electrolytic, which can be seen in "Image 2", it goes through the rubber grommet. Can anyone help me to understand where it should connect please, and what it's purpose is?

Secondly, I noticed that one of the caps is deeply cracked and needs to be changed, see image "Cap". The brand appears to be "WIMA"? This particular 3300pF cap connects to the EABC80. However, there are several others of the same type. These show surface crazing of the brown glaze, but no cracks. Should I replace them all?

Many thanks in advance.

Regards,

Gary
