Thank you Tom , as always your knowledge and advice helps steer me in the right direction .
The series feed which is now comprised of a 15uF PP and the 1uF yellow bypass is on the mid range , also the 1uf is a Clarity cap the was " Made for Thiel " and happens to be the exact same size as the ESA 630v cap ( that was used on one of my boards . Also as of now Clarity does not make a 16uf in the Purity series and the ESA , MR and CMR are very large in diameter I believe that a 15uf 400v Purity with a 1uf 800v-s Purity cap would be the perfect solution which now you've got me thinking about replacing the ERSR 15uf 400v .
While the schematic says ERSE inductors , Rob and the tags that are still on them say they are from Jantzen . When researching I discovered that ERSE does not make the values for the 2.7 . How much difference would one expect by using a 0.68mH 20 awg .569 DCR verse the 18 awg .440 DCR as used , or even using a 21 awg. .700 DCR or 22 awg .870 DCR ? The 0.60mH is used on both the tweeter and the mid .
I did it again , I installed the crossovers with the new Purity 800v cap before taking a picture ! But I posted pictures of the board on the virtual systems before showing the original (replacement by new Thiel) 1uf ESA cap . They show the 4 x 100uf electrolytics replacing the 1 x 400uf .
