Hi there new to these forums. I'm Arri and I like to tinker with things now and then and hopefully I'll be able to make myself useful at some point
I've been wanting to do this for a while...
I read a few posts on here about people who've replaced the OT in their rocker 30s
I was look at the classic tone 50w plexi ot and decided against it once I saw the shipping cost to UK then I went and found one from modulus right here in Scotland and another from a company based in Italy. They're both meant for 50w plexis but there's a slight difference in the primary impedance. Classic Tone is 3.6k Modulus 3.3k and the one from Italy is 3.2k.
So I was wondering is this a huge issue? Is either fine for my amp?

Not a huge issue, don’t go too far out of that range. Will present different characteristics. I’ve done transformer swaps on the rocker. The stock one is pretty good. Really no reason to swap unless it’s fried. I currently have mine set up for 6V6’s.

That's within range. I've seen tube data sheets listing optimal primary Z for 2 x EL-34 (Class AB PP) at 3,400 ohms. It depends on operating conditions (B+), but those OTs seem fine.
