BrianH	Re: Here's an idea for Randall and R.G. re: variable B+ Can you connect two different FWB's to the same two HiVAC leads from a PT? I've been wanting to build a "stereo side" for a rackmount mono amp that I built. Is it better to have a separate PT for each side or can they both share the same PT, if it is beefy enough? The Marshall stereo amps that I've seen have two PT's but I think the Mesa stereo beasties share the PT. Also, doesn't TUT2 cover a method of variable B+ of power reduction like what you have described? I'm wondering though, if several switches would be all anyone would need, i.e. one switch for normal operation, a second for half power, all the way down to playing at 3 AM in the morning levels.. Maybe a rotary switch!
