Hello folks ,and thanks again for adding me. I am in the beginning stages of trying to revive a 40-180 for an old friend. His grandparents bought it new  ,and I'm really hoping I can get it working for him. I have just started replacing ,caps , resistors. I was told I could use larger value electrolytics ,so I'm using 22uf. 
I have a couple of questions here in the early stages.
#1: How can I safely remove the pushbutton ,and coil assemblies so I can access the components underneath?
#2: The OT on this unit really confuses me. I'm used to OTs on guitar amps. This one has primary wires ,but no secondary wires to the speaker. How does that work if I need a replacement? 

Thanks in advance ! Tom
