Curious what bolt you members used to secure your transformer to one of Larry's cases?
I'll be putting mine together soon.
Also, is there mention somewhere regarding how to properly wire the transformer?
Thanks

the schematic is on DKs page, let me take a look.\

Use non-magnetic hardware, I used stainless steel.
Yellow/Red - right pin
Black/Orange - right blade
Grey/Brown - left pin
Blue/Violet - left blade
I have a question. My SDA 1C's were originally pin/blade and the IC has been modified by using a banana plug and a Vampire input jack so the blade side is no longer hooked up. Can I just run the appropriate connection from each side of the transformer to the negative speaker terminal? That achieves the same effect as changing the IC connector and re-wiring internally, correct?

Thanks for that link. I did look on there but may have missed it. Evidently again as I just checked. That's what semi prompted my post.Quote:

Correct!!
If I understand correctly, that is what I did as i had went to cardas BP for my IC cable.Quote:

Re: connecting the "blade" part of the SDA cable to the negative speaker terminal, that's what I did too. Works great!
Marine? Boats? Woah... I was just going to go to my local Home Depot/lumber store to find something.Quote:

Home Depot doesn't have stainless steel bolts. I got mine at the local Ace Hardware. The size I used was 5/16-18 x 3.5 inches.
Don't recall the size, I just matched the size of the bolt that came with the 800va transformer. Got stainless steel from the local hardware store.

Do I need to change them out ASAP?
I can access SS hardware from Jamestown Distributors on the Internet, if it isn't available in a local hardware or marine supply store.
The magnetic field would most likely be affected by steel hardware.
Also not all Stainless is non-magnetic so check with a magnet. Most stainless made overseas IS magnetic. so double check.Quote:

Aluminum bolts 3/8-16
I drilled out the center hub of the transformer. Not going to hurt it any..
Different selection in our stores. However, there are lots of places to go for hardware.Quote:

Just ordered stainless steel (18/8) bolts, nuts and washers from <www.boltdepot.com>.
They have a great selection of all sorts of fasteners, and its less expensive than driving 15 miles to the nearest REAL hardware store.
