GU-50 100W output and power transformers - Page 3

Wavebourn · 20th April 2007, 09:06 PM

Ok, I am ordering output transformers from Edcor USA (they gave the best price/performance ratio until now).
They will cost me $77.80 each when I buy a certain party. Northern Californian DIYers may pick up, otherwise please calculate actual shipment costs from Walnut Creek, California (94597) +$5 packing/ handling per parcel.

If you want to pay using PayPal please also remember that they charge a money for a butter on their bread. Since I don't do business on transformers it means they charge you.

100 Watt 10,000 ohms Plate to 4, 8, & 16
ohms
40% Screen Voltage 20Hz~20KHz
Classic Push Pull Transformer

Weight for each transformer is 11 pound (they are the same size, power and output transformers).

Power transformers (one per pair of output transformers, but you may order more for monoblocks) will cost $84.50 each for me.

Dual 120V primaries, secondaries 265-0-265 500mA, 12.6V 2.5A, 12.6V 2.5A, 60V 50mA (four secondaries) For a total 331 VA total power.

Please email me to arrange payments/shipments.

Hi Cobra2!

Let's calculate some details...

If you want, say, 6 trafos for example, it will be 66 pound unpacked.

USPS wants $374.25 for Global Express Guaranteed® Non-Document Service
I don't know why USPS calculator did not give other shipment options, I think some slow shipment should be available, no?

UPS wants:

UPS Worldwide Saver
584.25 USD*

UPS Worldwide ExpeditedSM
466.55 USD*

I.e. they will cost you almost twice.

Also, I'm negotiating with some Russian manufacturers. They quickly go, but slowly harness.

Well, still need to cover a shipment.

Last news: I paid now, they've charged a little bit more, so cost per OPT is $80.78 now.

They promised to ship output transformers tomorrow. Now, I have another problem: where to find right power trannies?

Antek sells toroids much cheaper than Edcor wants for E-core trannies, but when I ask Antek about slightly redesigned transformers they don't answer...

Which another sources to try?

Ok, ordering from Edcor USA:
Dual 120V primaries, secondaries 270-0-270 500mA, 12.6V 2.5A, 12.6V 2.5A, 60V 50mA (four secondaries) For a total 331 VA total power.
PLUS 6.3V 1A secondary winding for magic eyes
