There are many amps available with variable input attenuators. Achieves the same desired effect with a single pre.
Can I use two preamps?
OK, weird question here that someone might know the answer to. I want a Quicksilver tubed pre that does not have a balance control. The problem is I have to have balance because of hearing loss. If I get two of these puppies, will it do any damage to the output stages to run only one channel of each? Also, could I simply install one tube per amp? I know that I could consider the dual mono versions of the QS pres, but the new one is $$ and the old ones are hard to snag. Thanks for your advice.
