Default Primrose(SumR Audio) Toroid GB

In an attempt to fill the hole left by Antek, I have contacted Primrose of SumR about a GB for Toroids. While they are more expensive, in theory they should be of higher quality and more suited for HiFi. In an effort to get largest possible discount, We need to try to limit the VA rating of the toroids to two, maybe 3 different power levels. I was thinking 400 and 800 VA. At a quantity of 25, we get about a 12% discount, with qty of 50 bringing about a 25% discount. This is supposed to be per VA rating, but i think he make an exception if we can get the numbers up. He is willing to drop ship to locations, so there will be no added shpping cost over what is normal.
I think the best idea is to post your name and desired values and lets see where this goes.

Thanks for your effort Buzz

What is the cost of 400VA and 800VA transformers without discount?

They will be shipping from Canada?

Is there any chance that the shipment will be from USA?

The canadian overseas shipping cost is very high...

Thnk you again!

Rating - qty(25) - qty(50)
400VA - $73 - $65
800VA - $117 - $100

AS for shipping, they are Canada based, I can have some folks shipped to me and then ship them out, but i don't know if that will hurt or help.

What about 600VA for F6 and upcoming new Aleph J builds?
If not, will 400VA 2x18v be enough for F6 AJ stereo amp, or better go with 800?

I'm thinking 1000VA, and that's for A F-5 Turbo V2. Perhaps I am thinking too big. If this is for F-5 turbo V2 and V3, what is the plan...is a single 400 VA enough for F-5 Turbo V2? I think I put 2 of those in my standard F-5. Is 800 enough for a stereo F-5 Turbo V2? 2 800VA for V3?

Somewhere I got the notion to use 1000VA on a STEREO F-5Turbo V2....
Seems like 800 and 1000 VA may be the best two? single 1000 VA for V2, use 2 800 VA (or 2 1000 VA) for V3? Maybe I'm over estimating the VA needed here?

Thanks, I'm in for something here transformer wise!

I think 600VA is minimum for V2. I have 400VA and it hums a small bit with ear to cone. You can tell it is working. I would feel fine with 600VA, but would probably choose 800VA. I am getting 600VA because i am doing dual mono.



Rating - qty(25) - qty(50)
400VA - $73 - $65
600VA - $99 - $91
800VA - $117 - $100
1000VA - $139 - $120

List you name and exactly what you want. We might have to narrow things later, but will see how it goes. As long as you understand that things may change, we will be OK. Final price will be determined at closeout.

List names and choices like this:
Justin - 2 x 600VA
gmant123 - 2x400VA
ra7 - 2x400VA
