Need help re Quad 909 Binding Posts

I too own the 909, and had the same frustration. I went a much cheaper (and lazier) way: the side hole made for bare wire fits one of the prongs of my spade cables. The other prong stradles the side mount, away from the other output post for the respective channel. In fact, the geometry of the back of the amp also serves to hold it snug in place. I covered the other ("free") prong with some insulating caps, and it seems to work OK. Not ideal, I know, but a whole lot easier than changing the binding posts. You will leave a mark on the spade prong that goes in from the fastener, but if that's OK for you it may at least be a temporary solution.
Of course, if I set my house on fire doing this I will give you an update...

Though they are not intended for the purpose , this item from Parts express works great using bananas .

Ozzy: I must be missing something. The problem is for the 909 the fact that it does not take spades, not the reverse. What is needed is the revers conversion.

The plugs are out, so in theory the binding posts will take banana plugs. But I am finding that Vampire's SB bananas, which lock on to my Premier 11A binding posts just fine, do not lock on to the 909 very well. Maybe I need to try the BFA style or Nordost Z or Audioquest plugs.

Thanks for all the suggestions!
