rtaylor Posted August 31, 2003 Share Posted August 31, 2003 My 86 Lascala's have the AL crossovers and I'm looking to build a set of type A's. Can or should I use any of the parts that are in these already? In the future I also intend to build a set of Al K's crossover but would like to hear what all the raves about the simple A's are about. The price isn't a concern here. Does anyone have a list of components and maybe a location of where they are available? Thanks, Randy Quote Link to comment Share on other sites More sharing options...
Randy Bey Posted August 31, 2003 Share Posted August 31, 2003 yes sure use the existing parts. I basically rewired my AAs to make As. Left the unused parts still there, easy to go back if someone ever chooses. Quote Link to comment Share on other sites More sharing options...
JohnA Posted September 1, 2003 Share Posted September 1, 2003 Here are the schematics in 2 messages. I can't remember how to paste 2 in to one message. Some of the parts are reusable. The autoformers should be the same. If not, you can substitute the 3916 Al uses. Quote Link to comment Share on other sites More sharing options...

JohnA Posted September 1, 2003 Share Posted September 1, 2003 Also consider this. It has better tweeter protection than the Type A, with many of its attributes and premium parts. Quote Link to comment Share on other sites More sharing options...
rtaylor Posted September 1, 2003 Author Share Posted September 1, 2003 Thanks John, I'm printing the files now. The DHA looks good. On the type A it looks like the AL can be changed by adding two new parts? The 13uF cap and the T2A. Or will the T3A that's in there and the 8uF cap work? There are some blurry parts on the AL schematic. Thanks, Randy Quote Link to comment Share on other sites More sharing options...
rtaylor Posted September 1, 2003 Author Share Posted September 1, 2003 Not to forget you Randy, did you change the transformer and cap in yours????? What did you think of yours? Randy Quote Link to comment Share on other sites More sharing options...
Randy Bey Posted September 1, 2003 Share Posted September 1, 2003 The AA uses the same autoformer and basically all I did was rewire from the 13uf to the 2uf cap and not use the remaining 2uf cap. Sounds exceptional, better than one could expect from a crossover change. Quote Link to comment Share on other sites More sharing options...
rtaylor Posted September 1, 2003 Author Share Posted September 1, 2003 John, do you have a type AA schematic? TRying to see if RB's conversion is compatable with mmine,going from AL to A. Quote Link to comment Share on other sites More sharing options...

rtaylor Posted September 1, 2003 Author Share Posted September 1, 2003 Thanks Randy,guessing that I'll need to change a few components to acheive a type a out of an al. Do you agree? Randy Quote Link to comment Share on other sites More sharing options...
Randy Bey Posted September 2, 2003 Share Posted September 2, 2003 yup, you need a 13uf cap or some caps to wire in parallel to get 13uf. Call Universal Transformer in Wylie Texas and ask for their 3619 transformer. Tell 'em Randy sent ya ;-) Quote Link to comment Share on other sites More sharing options...
JohnA Posted September 3, 2003 Share Posted September 3, 2003 The Type AL has a 2nd order high pass on the squawker and maybe some EQ; the Type A & AA have a first order. You must change to the values of the A/AA if you want that type of configuration. I believe you can reuse the T3 autoformer. I'd try before I'd buy another autoformer. Both the Type A & AA sound good IF you take out the zener diodes the AA has on the tweeter. If you use premium components either the A or AA will sound great. The Type A has little to protect the tweeter from too much power, though. That's why I offered the DHA design. It will also attenuate the tweeter 1 dB to recreate the Type AA voicing.

rtaylor Posted September 4, 2003 Author Share Posted September 4, 2003 Hey John, thanks for the response. Decided to do the type A first(maybe that will be it!) You wouldn't have a list of your recomended upgrade parts for this crossover that you'd like to share? Any direction you could give would be appreciated.Randy Quote Link to comment Share on other sites More sharing options...
Guy Landau Posted September 4, 2003 Share Posted September 4, 2003 Hey Randy, I have used Solen hepta-litz, 2.4 mH, 10AWG inductors and stock oil capacitors. I've tried Multicaps and Hovlands as well, but went back to the oils. Quote Link to comment Share on other sites More sharing options...

rtaylor Posted September 6, 2003 Author Share Posted September 6, 2003 Better yet, does anyone here have some parts left over or old crossovers they'd like to sell?? Thanks, Randy Quote Link to comment Share on other sites More sharing options...
