Hi!
I'm working on some sources for power transformers.
In quantity one (1), we can get a *DUAL TAPPED PRIMARY* (to make adjustments for line voltage, etc), dual-48V 8.5A secondaries for
approximately $90. This is a $20 savings over Torroid of Maryland, and it's a better transformer due to the taps on the primary.
In quantity 50, the price drops to about $80 each, if we do a combined order.
I am also negotiating for transformers with the same specs from another transformer maker. I told them I wanted a price of under $60 each, and they are going to meet it! However, this would involve probably 200 units to get that price. Quantity one (1) from this source would be $100.
So, that's what's brewing in the transformer world.
I think with this pricing, the power supply costs are not going to be too high.
Oh, I am also negotiating with various suppliers of electrolytic capacitors. My goal is to do the whole capacitor bank for under $50 for all of them! I might even be able to do better than that. I did my bank for $32 - new parts.
Regards,
Steve
