This is very simple unless you have an expensive system $10k and need an (Elec. xover). To relieve some low bass from your amp and speakers try a .05uf 50v or higher uf, high quality cap, i.e. film and foil, in series with a 10k 1/2w resistor. (This value is a guess since we do not know the impedance of your amps.)Then put this in series with your hot imput, one on each channel. I put them on the RCA imput jack. Just get right in there disconnect the hot from the center of the jack and solder the cap/resistor in between the hot and the jack. One on each channel. This sounds great on my ST-70 triode amp! I use a .022uf and a 470k resistor(20hz). For futher info and formulas see the AVA site: http://www.avahifi.com/70rebuild.htm Good luck, and happy tweaking. Greg
