Output transformer/speaker load and active biamping

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I am new to tube power amps. I understand that you always want to have speakers connected to provide a load to the tube amp output transformer.

I am actively biamping my Magnepan 1.6 speakers. (ie. the crossover function occurs prior to the power amp). So my power amps are directly connected to my tweeter and woofer elements of my speakers. The speaker drivers themselves present about a 4 ohm load (even without the crossover elements that would otherwise be there). This works fine with my SS amps today.

Moving to tube power amps, will the amps directly connected to the tweeter/woofer panels be ok and present the proper speaker load to protect the tubes and output transformer?

Currently I have a 63uF capacitor in line (on the + terminal) of the tweeter connection to my amp. The purpose of the capacitor is to protect the tweeter from DC/startup/shutdown thumps from my SS amps. Will having this capacitor which blocks DC cause any problems with proper operation once I switch to a tube amp?
