Solder Sniffin Time

The Eagle landed with my Parts Express Care Package. Gonna recap Bozak B302-As with Pat Tobin's 101T Crossover recipe. Basic Dayton Polys and 2% Resisters.

I'm a picture posting virgin, but I'll try to get something up when I'm finished.

You can upload pix to the AK server if the largest dimension is 640 pixels. Use the "Attach" button, locate the pic on your PC and hit Upload. It'll show a thumbnail, which will expand when clicked. Most photo programs have an option to resize photos for email; that should work just fine.
 
If you're going to be sniffing the molten solder, I highly recommend the lead free, high silver content variants...(lol)
 
what am I missing?

I got the software loaded, took the pictures, got them on my computer, but they are still too big to upload.
 
Almost every photo-editing software has some facility for resizing photos. If you're having a problem with it, let me know what software you have & I'll try to help.
 
Pictures finally, maybe

Here are a picture of the crossover before, and a distant shot of after. The two open back photos show the damping curtain up and down. The black crossover top is in the down picture just to hold the curtain back. I'll attach a better after shot of the crossover when I get it shrunk to size. Thanks to Paratima for help shrinking the pictures for me.

Alan

New Crossover and Speaker Fronts

The new crossover picture is (should finally be) attached. There is also a picure of the front in Italian Provincial. Original listening impressions sound real good. Image is better, mids seem stronger and highs are noticably smoother.

The original crossover had the midrange wired out of phase. I have read reports of others finding the same thing and there seems to be some uncertainty as to whether or not it was a factory mistake.

Another interesting fact that I learned in my Bozak Group research was that all of the larger Bozaks came with the curtain hung from the top. Thanks to Pat Tobin, and the people from Bozak Group that helped me keep my act together.:thmbsp:

maybe that lead thing had something to due with the fact that it took me about 7 years to figure out how to post picture.

watershed day,

i couldnta did it without your help. i never had me no avi tar before. been hanging out on web boards for over 10 years. It is nice to make a contribution, as opposed to picking brains.

After more listening, it really cleans up the highs and mids. After hanging out here and dialing in some decent vinyl rigs, CDs were almost nasty through these speakers and SS ampage. I really noticed the difference while zoning out on some CD Pink Floyd. That really helped me put my finger on the differece that the reworked crossovers made.

A differant thread but similar results to the recent tubes (my first) that I plugged into some Crites worked Heresy IIs. Haven't put the tubes to the Bozaks. Limiting experimentation to better evaluate the mods


Redone network looks mighty clean. Even became your new avatar, I see. Nice work!
