Yeah, my understanding is they have better trannies now. Still ....I think the Mojo kits are better, due mainly to some small things, like the IEC socket does't fit firmly in the chassis cutout and pops out or is loose etc. for the Weber. The caps/resistors look real cheap also. But if the savings was enough I could go for a Weber kit.I bought two of the imported Weber transformers years ago to use on experimental/prototype amp builds. Both failed.
I love Weber speakers to death but I don’t use any of their amp building supplies. There’s no reason not to use Hammond or Heyboer when they’re both reasonable priced.
If you wanna slurge, I agree with Tavo. Spend it on the output transformer.
