I use a custom made 8 ohm attenuator for home playing with the same amp. For me having one is a must since you can't really hear how good the lead channel is if the master volume is below 4 (or even 5). And in my room and with my cab that's way too loud! However, with all attenuators I've tried...

Well, there seem to be conflicting opinions on that particular topic and unfortunately I am not an engineer myself to be able to confirm or deny any of them. At least everyone agrees that matching impedance is the way to go.

Actually I was asking something else. Let's say I have two absolutely identical cabs with the same type of speakers, the only difference being that in the one cab they are 2 x 16 ohm running at 8 ohm parallel and in other other one 2 x 8 ohm running at 4 ohm parallel. Would there be a difference...

Hi guys, I have a question about the output options on my Mesa Caliber+ 50 head. I'm using it with a Framus CR212 cab that originally had two chinese Celestion Vintage 30 speakers which I didn't like. They were 16 ohm and wired in parallel for 8 ohm. I sold them to a friend and as part of the...

Thanks anyway, I will get some TAD Highgrade and NOS tubes and experiment :)

Thanks, I was thinking of something similar. What about the phase inverter (V5 I guess). I know many people consider the PI the most important part of the preamp after V1 but I don't have a clue whether I should be using 12AX7, 5751, 12AT7 or even 12AU7 there?

Hi Guys, New Mesa user from Bulgaria here! I just bought my first one a week ago. It is a Mesa Boogie .50 Caliber+ head made in April, 1989. :) I have to say I was quite disappointed when I turned it on for the first time. It sounded quite lifeless on both channels with the lead channel...

I also have a .50 Caliber+ and the signature says 89/4. P.S. New to the board, I got this amp a week ago and it is my first Mesa :)
