Yep I did not many changes it might be something related to caps or diods or the voltage on the plates I will contact another Mesa tech to give it a look ;the circuits on those things are not easy cake,will keep you updated cheers!

Hi Danut, I got your point, I've plugged in different guitars from Ibanez, Fender, Ernie ball, but not much difference also when you set the output on 9 -11 it rises up the volume with more room but not many changes about saturation, it gets even worse. :(

Hi Mark V user, unfortunately it is an optical illusion, I might going to see a tech this weekend, the voltage has been set up at the right voltage 240/50hz I think when they sell Mesa amps new, they are already set up for that specs as the previous owner told me, he bought the amp new and...

Hello again, I was able to make a short clip to give you a better idea, I have used channel 2 and 3 with 90 w settings and equal on both; Channel 2 set on Mark 1 and channel 3 on extreme function, the Master volume was set at reasonable volumes and the output knob at 2 pm. It is a nice sound...

Thank you for your reply MarkV user, I will post soon a video link with a sample for both channel 2 and 3 I am just waiting to relocate at the moment and I got all my stuff packet but I surely will once I'll set up everything in my new place. I am not a real expert on electronic and amps...

Thanks again, unfortunately I am not an expert I really beleived once the preamp tubes were replaced I could get a better response but it didnt much changed. As I ve talked again with the last technician after he did some basic tests he wasn t able to find any big issues I will soon post a video...

Hi bandit2013 I decided to change all the preamp tubes replacing them with original Mesa 12ax7 before I did the comparison with the other amp but not much changes.

Hello, I definitely will soon I am just moving to another place once all set up I'll do if it can be posted with a free account.

Hi rarebitusa , I think I did that previously, that switch is on the back panel and it takes out the loop function, but unfortunately it didn't change much, and I did also switch off the GEQ but not many improvements.

I can get a nice distortion, however, if I want to have something more powerful I need to use some pedals on both channels. If you also check some mark V videos on you tube even with channel 2 I should be able to get a powerful distortion with the right settings which unfortunately I can't. It...

Thank you for the reply bandit2013, The new amp had the STR441 as I checked, I am not sure about the bias color. Both amps had same power 6l6 and preamp 12ax7 Mesa original. I also switched the triode/pentode function but not much changes. if I use both channel 2 and 3 and on both I try to...

Hello everybody, A few months ago, I've bought a second hand mark v 90 w head and I after a while I have noticed that both the lead channels weren't able to make a saturated sound which it could be expected when you rise up the gain knobs so I decided to replace both power and preamp tubes and...
