Hey, I have a simul class Mesa Mark 3 Purple stripe Combo that I got a long time ago. I took it to a tech as the power supply died and he put in a fender power supply and 6550 tubes. The amp was sounding great but about 5 years later the clean and the lead channel got very thin almost like a...

Hey guys, so my buddy has a triple rec 3 channel and he has not changed his tubes once he got the amp used 6 years ago. He ordered some Mesa tubes so I decided to help him out and change them out for him. He opted to try some EL34s (STR447) this time over the 6L6GC that were in the amp. I also...

I suggest when you bring it back to stock, you do the Mr scary mod if u want more gain. It’s sounds fantastic and it’s 💯 safe

I mean its based on a greenback with more power so you aint wrong

The Mark series 5 band eq (as im sure you know) is post pre amp and is affecting the power section so maybe play with that eq a bit and see if maybe you can dial to taste and it gets u closer. I. have. not had much luck with WOS and two nots IRS tbh, I find them very scooped and dark. and boomy...

I don't find the Suhr scooped at all, in fact I find it. has more mids than the captor. I find it to be quite close to the actual amp. May I suggest trying different IR's and a different IR loader. What are you using atm?

I really hope its not at "Scary" as it seems lol. Will update later. Actually didnt notice anything out of the ordinary with the JJs but I didnt really pay as close attention as I should. Question: I put back the. stock. Mesa EL34s in no real order and it occurred to me it may not be a matched...

Hope so, will try it in the bandroom at proper volume tomorrow

So I grabbed a new ecc83 and took out the mod and swapped it in and it didn’t fix the issue. So I then did the remaining 4 slots one by one and it didn’t fix the issue. So I decided to swap out the JJ EL 34IIs for the stock Mesa EL34 tubes that came with the amp and it has seemed to have solved...

Ok will try that. The mod has been in there a month or so with no issues thow.

Need some help, having a strange issue. As u can hear in the vids the amp when not playing sound like it’s getting interference then pops. When playing this results in a louder volume when the interference is happening and when the boop happens the volume drops. Any ideas. It’s a Badlander 100...

You don't. have to remove. the chassis, just remove. 2 middle power tubes.

I just got scammed myself, but I didn't use. the. friends and family so I hope I will get my money back. I reached out. to paypal.I always have to learn the hard. way lol

Awesome

Just did the Mr Scary mod in the Badlander and its rather great. Did a quick vid when I got it, no real super dialing in, just left my eq the same and moved gain. Did 12 O' Clock on crush and crunch pre and post mod, as well as full gain crunch and crush pre and post mod, although full gain with...

Hey guys, I got the JJ's from Eurotubes, so I did some clips to showcase the differences between the power tubes and the preamps. MESA EL34 STR 447 BLU with MESA PRE AMPS JJ EL34II with MESA PRE AMPS JJ 6L6GC with MESA PRE AMPS MESA EL34 STR 447 BLU with JJ PRE AMPS JJ EL34II with...

I wrote them, waiting on a reply. Wrote you guys first thow lol

Nah he is not an official Mesa tech. I don not live in the US so it will be a last resort for me to ship the amp to the US to get sorted. My tech is very good and has replaced the components that were damaged but we were trying to confirm his theory correct so we know the issues will not return.

Thanks for helping, I will pass this on to my tech.

Ok cool, hoping then an engineer type in here with his/her infinite wisdom could probably tell me what those resistors and caps in that section of the of the circuit govern.
