Interesting exchange here. When I was reading about amps with rectifier tubes vs solid state, I was a little confused. A while back, I got really lucky on ebay and bought a "blackfaced" 1974 Fender Super Reverb for $800. My amp tech told me I got a good deal. He checked the amp over, changed out the speakers and called me to talk about a rectifier tube. I'm an electronics idiot so was looking for advice. He said that whoever had this amp prior to me had installed a solid state rectifier and he wanted to change that to a tube rectifier. It wasn't very expensive, something like $25, so i said go ahead. What a difference that made! I vote for all of the power components being tube. No expertise here, just know what sounds good. I also bought a Heritage Patriot - Yep, tube rectifier in there. No matter what anyone says, guitars will have their best, most pure sound with tubes. Go to guitar center sometime and play through a Cybertwin - all solid state excet for one preamp tube. They are aweful!
