it was an very large can, and was ac electrolytic , 3uf and I think 275v or 375v
I fitted an 2uf 630v Polyester or other plastic film Capacitor and a 18 year old 2uf motor run capacitor! I payed for a 1uf 630v capacitor to go with the 2uf to make up 3uf but I am still waiting for it to arrive!!!
I think the hum cancellation circuit is very strange, but as it wants 3uf I can have 4uf or 2uf? which is better?
