Title: Vox AC30 transformer specifications please
Post by: arielfx on July 16, 2004, 04:02:37 AM
I thought to build an AC30 for my next amp project (ya I know I should finish the current one first, but's the way I am).
It seems that the schemes and layouts are just about everywhere online but I don't see any transformer specifications and I don't want to spend around $200 per one if I can get a hammond transformer with the same ratings or if they don't make a model that is 100% compatible - I know a local guy who build great transformers and would do it for less.

So... if anyone got a good source for the PT,OT & choke please post it here and it will help me out!

Mercury Magnetics seems to be a favorite source among the experts.

I checked with them man but as I said, I want the specifications and not some link to someone who makes them because there are tons of those and I don't want to buy from these places because that would very expensive and shipping here (Israel) is not that cheap either and import taxes would be high so I rather get a Hammond model which is pretty close is spec. or pay a local guy to build it for me.
