Merry Christmas! So.... Just wondering if anyone other than me has built their 1000VA Dready yet?Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

I finally picked mine up from the post office. The box was a wreak but the tranny was flawless. Can't believe how big and heavy this thing is!

Merry Christmas to all!!
My hesitation is (in part) to the wiring. Is it the same as the 800? I cannot find any mention of different wiring. PLEASE confirm

I cut and pasted the information below from one or more of the threads about construction of the 1000VA AI-1 transformer and saved it for my notes. This is how I built mine, and it works superbly.
The wires on the AV-047528 use the same color scheme and parallel connections as the Y236906:
For the Y236906 800KVA transformer, the Avel-Lindberg website has a chart for parallel connection of Y23 series transformers showing the primary positive terminal attached to the gray & brown wires and the ground terminal attached to the blue & violet wires. The dots indicate the corresponding + or - terminals on the primary and secondary sides to maintain correct polarity and phase.
The red and yellow wires on the secondary side should be attached to the positive terminal and the black and orange wires to the negative terminal.
My connections at the speakers are:
Right Pin (+): Red and Yellow wires.
Right Blade (-): Black and Orange wires.
Left Pin (+): Grey and Brown wires.
Left Blade (-): Blue and Violet wires
In other words, to parallel, put 0 to 0V negative (blue & violet) and 115 to 115V positive ( grey & brown) on the primary side and 0 to 0V negative (orange & black) and 115 to 115 positive (yellow & red) on the secondary side."Science is suppose to explain observations not dismiss them as impossible" - Norm on AA; 2.3TL's w/sonicaps/mills/jantzen inductors, Gimpod's boards, Lg Solen SDA inductors, RD-0198's, MW's dynamatted, Armaflex speaker gaskets, H-nuts, brass spikes, Cardas CCGR BP's, upgraded IC Cable, Black Hole Damping Sheet strips, interior of cabinets sealed with Loctite Power Grab, AI-1 interface with 1000VA A-L transformer -
Correct, exactly the same as the 800. I just used my 800 as a guide and it worked perfectly.Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

Sorry. No, there are none left, and it's not possible to just purchase a single unit. Avel Lindberg will only do a run of these with a minimum purchase of 10 units, that's why I organized this group-buy. I was soliciting people to join the group for over a month. Your only option is either to purchase a smaller transformer, or put together a group-buy of your own.Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

Michael, I've built Dreadnoughts with both the 800VA and 1000VA trannys from A-L. The performance of the DN using the former is probably 80-85% of the DN using the latter. IOW, the smaller tranny still makes a very good AI-1, and produces easy to hear improvements in clarity and soundstage.
The 800VA is available off the shelf, and is considerably cheaper."Science is suppose to explain observations not dismiss them as impossible" - Norm on AA; 2.3TL's w/sonicaps/mills/jantzen inductors, Gimpod's boards, Lg Solen SDA inductors, RD-0198's, MW's dynamatted, Armaflex speaker gaskets, H-nuts, brass spikes, Cardas CCGR BP's, upgraded IC Cable, Black Hole Damping Sheet strips, interior of cabinets sealed with Loctite Power Grab, AI-1 interface with 1000VA A-L transformer -
