CECAA850 Posted January 8, 2017 Author Share Posted January 8, 2017 Ok I think I've got it now. I'll start to deconstruct after I find out what time Miami plays Pittsburgh. Bob's coils should be here this week. 1 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted January 12, 2017 Author Share Posted January 12, 2017 Got my coils yesterday but may be a week or 2 before I get to play with this. I'll be out of town the next couple weekends and have very little time in the evenings. 1 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted January 19, 2017 Author Share Posted January 19, 2017 There are no labels on my T3A. Did I labelieve the connection called 1,2 and 3 correctly in the 2 schematics? Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted January 19, 2017 Author Share Posted January 19, 2017 @Deang if I lay the bus wire down as is my squawker will be miss wired. Shouldn't I tie all the negatives together? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted January 20, 2017 Author Share Posted January 20, 2017 I just read the disclaimer in step 13. This might be a deal breaker. Anyone have any thoughts on my questions? Quote Link to comment Share on other sites More sharing options...

jwgorman Posted January 21, 2017 Share Posted January 21, 2017 Rev 1.4 of my rebuild. It's fairly straight forward. I am not building it exactly like you are btw. Step 11 is easy to overlook but important. Your autoformer is -6db, I replaced mine with the 3636 so I could see how much attenuation I wanted. I don't think there is a "right" answer, but after moving to the A55Gs, -3db sounded best to me in my room. Good Luck! Quote Link to comment Share on other sites More sharing options...
Harleywood Posted January 21, 2017 Share Posted January 21, 2017 I've always found these work wok pretty good in most modestly priced units. Quote Link to comment Share on other sites More sharing options...

Deang Posted January 22, 2017 Share Posted January 22, 2017 I'm not going to be out here much anymore. I made a mistake. The polarity of the midrange is reversed, so yes, you are going to have to straighten out the buss wire, and ensure that it's negative/positive all of the way across. To figure out the leads for the TA3, I was going to tell you to trace out the circuit - I don't know how else to do it. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted January 22, 2017 Author Share Posted January 22, 2017 I've got it figured out. I hope the lay out is ok. It's the only way I could fit everything and keep the existing holes used to mount the crossover to the speaker. Quote Link to comment Share on other sites More sharing options...
BEC Posted January 22, 2017 Share Posted January 22, 2017 I think the air core inductor may be too close to the steel frame of the autotransformer. I would place it well away from the autotransformer. Bob Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted January 22, 2017 Author Share Posted January 22, 2017 Well crap. I have one half way wired up already. Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted January 22, 2017 Share Posted January 22, 2017 Carl, don't know if this has been addressed in this wonderful thread....but how/why did you decide on those caps? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted January 22, 2017 Author Share Posted January 22, 2017 I wanted the same style cap that they came with originally. Quote Link to comment Share on other sites More sharing options...
BEC Posted January 22, 2017 Share Posted January 22, 2017 How about swapping places with the air core inductor and the zener diodes? Quote Link to comment Share on other sites More sharing options...
