Although I'm very fond of the power aand pre amp, I could do without the lexicon, in my opinion digital reverb is not very good for guitar. One of these days I will replace it with a rack mountable spring reverb device.

Both of your Mesa amps probably have what we call "heavy iron" power supplies. That means big transformers, and linear regulation (if any!).

The Lexicon is a likely candidate for a swichmode PS. That is not necessarily a bad thing. Living next door to someone who parties a lot is only a problem if they're making noise when you really want some quiet! :)
