Holmz Posted January 5 Share Posted January 5 (edited) It looks like all the dip switches need to be off for 100k input impedance of the amp, but the used M5-HPFs are old, and I noticed a 9V battery inside.Should I be rocking the PCB back to get to it, or just desolder the old battery at the posts and solder the new battery at the posts? It looks like it should be easier to desolder the old batter at the PCB, and then solder to the posts of the new battery… and then solder the jumpers to the PCB as the second step. Almost tempted to attach a 9V regular battery plug in harness, but I suppose it is a better connection with the solder. Another question, which I assume is “Doesn’t matter” is:Does it matter whether I put these near the preamp? Or near the amp(s)? I guess the third question is…Do the teflon caps do much for the sound? I’ll be running these on the 2C speakers for now. I’ll likely “move on” the 2W and the RCA HPF from them. Edited January 5 by Holmz 1 Link to comment Share on other sites More sharing options...
