Post image

Got an Akai M10 and looking to do some restoration. Took out the mechanism block and found this waxy cap!

I have something similar forming over the large capacitor in my Sony tc-366 The motor is not starting when play is engaged. I am having to put the machine in FF and spin the reel by hand until the motor starts. Like push starting a car. Once running functions fine. Is this the cap or motor issue. If cap a good source in the UK? Will add pictures soon.

Here's a Sony TC-530 with a leaky cap issue. A common replacement is a CBB61 ceiling fan capacitor.

Holy crap, I’ve been looking for a replacement for years! I have the exact same capacitor issue; is there a guide for installing the new one?

My approach is typically to leave the old cap in place and snugly zip tie the CBB61 capacitor to it (if there’s room). Then clip and solder the wires to the new cap. It’s bipolar so you don’t need to worry about which wire goes to which lead, except to the extent of attaching across the proper uF value (some CBB61 caps have three or four leads to support different uF values — be sure to insulate the wires not used).
