Which opt

[Trapperbob]

I have a kalamazoo two that needs a new opt, which one from Hoffman should I get? The champ replacement? I would like to match the original as close as possible. Thanks

I believe the K2 uses an 8 ohm speaker so you would need the part number Mojo771. However, Hoffman is out of stock and I don't think he will be restocking that transformer. But you can get it direct from Mojo...
