Erik Mandaville Posted October 15, 2006 Share Posted October 15, 2006 These are for our Heresies. I wasn't doing anything else this morning, so I thought I would make a new pair of crossovers. I installed a piece of veneer over the old boards to cover the old holes and make them look nice; gave a quick shot of clear, and then wired them up. The old air cores measured slightly above and slightly below 1 ohm (that's for the two coils), and I wanted to improve the DCR and save a little money at the same time. Time to put them in and listen to some music. Erik Quote Link to comment Share on other sites More sharing options...

sfogg Posted October 15, 2006 Share Posted October 15, 2006 Erik, Looks good, the veneer over the old board is a nice trick assuming it sticks well. Which pair of Heresy are these for? Shawn Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted October 15, 2006 Share Posted October 15, 2006 Mahogany? boards...... wowee, or is that Oak veneer? why the double-up caps? to get the requisite values in the brand you selected? And are those iron core inductors far superior to the ones used originally? Those are to filter the highs from the woofer, so seems like you'd want that BIG WIRE in there.

3dzapper Posted October 15, 2006 Share Posted October 15, 2006 Erik, Love the red/silver, black/white and earthtone motiff. That yellow has to go!!![] Yeah, your right they might work better with a ground. Rick Quote Link to comment Share on other sites More sharing options...
Erik Mandaville Posted October 16, 2006 Author Share Posted October 16, 2006 Shawn: I bought the veneer to repair old clock cases, and it is tough stuff. It is the iron on type, with a very strong adhesive. It is on there to stay. I was going to paint it flat black to keep it more original looking, but thought the contrast was kind of neat. These are for Heresy Is. Caps are just paralleled for the additive value -- easier to do with less expensive but decent capacitors. Rick: I grabbed them off my workbench for the photo before we went out. Rushing stuff is never good. The networks are back in the cabinets, and I just have to finish the new leads to the drivers. I wanted to get them finished yesterday, but had too many other things to do. Erik Quote Link to comment Share on other sites More sharing options...
Erik Mandaville Posted October 16, 2006 Author Share Posted October 16, 2006 I wanted to mention that the autoformers are from Bob. C. They are very well made, too! I found that the solder lugs for the different taps also had a thin coating of lacquer that I wanted to remove before making and soldering connections to them. For those who might be interested in a pair for a crossover project, you might want to check that, and remove the clear coat with an emery board or careful use of an x-acto knife.

Kudret Posted October 16, 2006 Share Posted October 16, 2006 Erik, I was planning to do exactly the same thing to my Type As before I replace the caps with soon to arrive v-caps. Kudret Quote Link to comment Share on other sites More sharing options...
Erik Mandaville Posted October 16, 2006 Author Share Posted October 16, 2006 Kudret: You're going to use veneer over the old boards? Is that what you were mentioning? I think the type A is a good network, as well. Erik Quote Link to comment Share on other sites More sharing options...
Kudret Posted October 16, 2006 Share Posted October 16, 2006 Erik, I have some leftover walnut veneer that I was planning to use over the old boards. As for Type As, I like them the most among the other networks I tried. Kudret Quote Link to comment Share on other sites More sharing options...
