No, it's the same. 448v from the OT to the power tubes.

Not tried myself, but interested! Any idea how much shipping and customs would be to Europe? I mean, they are in the US, so....

i was ordering many times from US, it is like 150usd for trafo, 60-100 usd for shipping, and on all it is minimum 25%
250x1.25=312 usd, yo pay double, too expensive, and for unknown result :idea:

sure bet is only original fender transformer, SF, BF, but usually are only 4 ohms.. nothing to be worried about because they are good also for 8 ohms..

the sound is in lamination and wax/impregnation :wink:

Some 15 years ago I did my last order from Brian Wallace. Can't remember it being this expensive. Hell, I imported a complete Metro JTM45 kit in 2007 for $168 shipping and less than 10% customs. Still expensive, but 100 bucks shipping on a transformer is outrageous in comparison...

It's the "unknown result" that begins to worry me. I actually never thouyght PT's would mean a big difference, but this time it was huge, meaning, to me, useless.
