Lowe's (my only choice around here in Murphy) is scaling back their bulk wire so I will see what they still have available.

Thank you Dean, I found the price difference between the Litz vs non was about $6 total for the four coils so I went ahead and got them. Wow, those AudioCap PPT Thetas are way out of my present price range. But the way the layout is setup it would be very easy to change out the caps at a later date.

I stand corrected, I could not find any mention on their site about any exchange. I went forward in placing an order and it wasn't until we were in Papal did the exchange rate was shown. It is currently at 1.30 which works out to .77us per $1 can. Thanks, I did order everything I could from them.

film & tin foil caps? Could you give me a few venders that offer them? Also are we saying that the DCR of the 1.6, .20 & .30mh coils are not a factor to be concerned then? I believe the #18 2.0 steel laminate was below .4 ohm but will confirm this. Just checked, it is .26 ohms

Great idea, I will get a few feet of 3/12 or 3/10 wire and cut out the ground. Thanks

Already have a spare set of T7A's, would love to get everything from one place but Solen doesn't have everything needed. Besides all the ancillary fees add up quickly, as simply as adding eight resistors adds over $4 to shipping

As I understand it they were late 1989 as the II's were released in 1990 through 1995 or 6

Thanks, I could have follows the schematic but this will make things much easier for these old eyes Haven't decided on what to use as a common ground, like the braid but just can't find any without getting a crazy amount/price. Also thought of buss wire but again the same deal with the braid, money is very much an issue so I will most likely make the spine out of 14 or 16 gauge wire from my junk box. Any more thoughts of using smaller gauge inductors? Looking at #18 2.0 iron & #20 (18?) air for the 1.6,.20 and .30. As thorough as ALK seems to be using a smaller gauge can and will change (increase) the DC resistance values so it raises the question if this would be a factor in the design enough to require other changes.

I did find ALK's board layout and will follow it for my project.

Having spoken with him directly I can easily see where all of you are coming from with ALK. Being I came on here well after the fact it was my nature to give him the benefit of a doubt when I read his comments on his web site. Luckily I was able to find his design for the Forte II. As on the coils, I will look at the cost difference and if it amounts to a sizable dollar savings I would go down to "regular" parts. Aside from cost and possible size is there any reason not to replace an iron core with an air coil inductor?

Sure did, I started a new thread sbout it.

LeeW, looking at the few values I can read this is for a Forte I, did you replace your k25k with a k23k driver? Some of those components are out of my price range ;) . Thanks for the pic.

Oh, OK I priced out all components and between Meniscus and Solen the price is 2 x $73.xx + shipping. This price is with Solen caps & air coils, the iron core will be from Meniscus. I could put up part numbers & prices if there is an interest. for them

Curious CECAA850 as to why you asked if I were to be building these, is there something I might need to know or consider?

That makes sense, thank you.

could anyone tell me what the .66mh/6.8ohm "add-on" is for? As we know the Forte II has a k-25-k driver so what determines when the extra components are needed?

I want to thank opusk2k9 for sending me a pm that Klipsch still had these available a year ago.

I am considering it, looking at cost of parts. At a quick glance it would be $170+ in the components. I had called him and attempted to purchase a kit but was informed he no longer offers them. Sad that the actions of a few people ruin things for the rest of us.

Would litz wire truly be necessary at audio frequency's? I understand the theory behind it and question if one would really need it at these frequency levels. If yes a source?

I have started a new thread about this at

I wanted to move this to a new/fresh topic as it was so deeply nested in an other thread

Thanks, I believe I found it
