Title: capacitor break in set up
Post by: kip.duff on March 07, 2017, 10:56:34 PM
Putting together my BeePre- then the Eros.  Want to break in my various caps before install if possible.  Pretty sure I saw burn-in info in these forums, but after extensive search, can't find now-

I have a $30 Yamaha receiver I bought on Craigslist that I used to burn in my Fostex speakers with "Irrational but Efficacious" break in CD.  I have the 10uf (may use 6.8uF?  better fit)  Russian K73-16 caps for now.  Connect in series with 5 Ohm resistor then run accross speaker outputs of the receiver at moderate/high gain levels?  Able to do more than one at a time?  If so, how configure?   

Thanks, Kip.......

BTW, Fostex/Madisound BK-16 Nagaoka speaker kit with Fostex FE168FE Sigma drivers very nice with my Paramount 1.1s.

Kinda spitballin' here but I think you could connect each cap/resister combination in parallel with the speaker outputs.

The Impedance of each parallel path should be equal - same resistance and same capacitance or capacitive reactance.

I think we do this when we connect speakers in parallel, combining the same resistance (wire) and inductive reactance (same speaker).

Put the caps in series with those Fostex speakers and run them for 100 hours.  With a 10uF cap in series with each driver, you aren't going to be stressing out the Fostex drivers much.
