Default Antek toroids recommadation

I need toroids for my aleph j and f3 project. I'm no sure wich of the Antek toroids to purchase. They have a new line of audio toroids but the max Va is 400. So I'm in a dilemma, Should I buy the AS-4218 or the AN-5218. The AS-4218 have static shield between primary and secondary, but it is 100va less. What the tradeoffs between those 2 toroids ?

Thanks

I have a 600VA AS-6218. Nice transformer, and not very much more $$ than the 400 or 500va models. Big enough for a later project if I ever want to cannibalize my F5. (which I doubt I would do...)

I just got the 500VA model for my latest F-5 build, it should do nicely.

I didn't see a AS-6218 listed on their site. I only see an AN-6218. If they have a 600VA with static shield that would be nice. What was the cost?

I used an AN-4218 on my F3 and can't complain about it, it works grea and is quiet.

The same for my F5, works fine, and I've had no power supply issues.

Sorry, I misquoted, it's an "AN" .

Still, it's a nice transformer.

Are you going with one per channel, or one to drive both channels

Both Channel.

By the way, I use an-4218 for my f5, but I think my ac line got a lot of dc, that's why the transfo make a lot of mechanical hum. I install in the f5 som big caps with bridge rectifier to get rid of the dc. It help, but the hum is still there. So, does static shield help to reduce mechanical hum ?

Thanks

I've had a half dozen Anteks. They are great. While I don't really notice a difference, I like the shielded versions for the few extra dollars. I tend to buy one size bigger than I need for freedom in the future.

Remember, they are spec'ed for an extra 20% VA over what they're marked for. So a 400VA can deliver 480VA.

I've had a 50VA, few 400VA, 500VA and even an 800VA- all great.

Perhaps most importantly, Jon at Antek is very responsive and helpful.
