SF fender champ question, where should i post it?

I'm new to the forum, and not sure where to ask this question, but I have been researching using external speaker cabinets for my SF champ. But where are these guys finding an RCA to 1/4" speaker cables? The champs and vibro champs that I've seen and owned have the RCA type connectors for speaker??? I can't seem to find a speaker cable thats RCA to 1/4". Am I missing something obvious?

Post in Amp Central Station for the best responses.

Look for an 1/4" to RCA adaptor, not an entire cable.

This will do it:

Just have the RCA jack replaced with a 1/4" Switchcraft jack. It's an easy mod and can be put back to stock if you want, but you likely won't want to. The problem with the adaptor strategy mentioned above is that if the adaptor falls out while you are cranking the amp the output transformer will likely be toast.

I'd go with Dr Bill on this one.

Thanks for input. Changing jack next week. Appreciate you guys!!!
