for jonyoung...

Hey I have 2 ART Pro MPA's just like you and I had read your post a long time ago about how you swapped out the tubes. I have tried to locate either some westinghouse 12df7 or raytheon 12df7's but to no avail. Any other suggestions as to what kind of tubes I could try. I'm looking for one with possible a warm sound and kind of on the darker side. Thanks for your help.

simple technical question about resistors?

...so: I have a cheapo set of computer speakers that use a subwoofer that is a bit too loud. There is no volume control for the sub, but I imagine I could add a couple of resistors to the line that feeds it to lower the level.

Will this work? If so, what value might you smart people suggest to lower the level, say, 3db? 5db?

thanks!
