I have some original adcom equipment GFA-1A amp and a GFP-1 preamp. I have had some cold solder joints repaired several times and noticed that when the amp warmed up my left channel would come back. Call it foolish but I have had the amp and preamp on constantly for about 5 years. No problems.
Leaving Amps on
I am wondering, in the case of which is best for the speaker, is it best to leave the amps on all the time, or shut them off between use. I know that turning them on and off causes heat expansion in voice coils leading to stretching; The main reason that pro audio setups that are permanent stay powered up all the time. But, is it really best? Can I also cause long term damage to the speaker by leaving it powered up with no signal being sent? I just recently read an article that said too much continuous power can burn the parts in the coil. Can anyone help? Thanks in Advanced! Sam
