I've sent in 6 IIc's for the upgrade. Later IIc's are closer to a c+ but still need the upgrade to become a great amp.

Mine has a leftover Gain Boost faceplate. I found some orange pilot lights so all of my Mark 3's have them instead of the blue ones.

Nice! I've been playing through my No Stripe DRG lately. It also has the 105. I sent it to Mike B. for service and the R2/+ mod. I have Chinese Square Getters and 415's / 416's in it. They're great amps. Very close to a c+.

Here's some pics. Hope it helps.

I have a c+ with 6 12ax7's. Mike B. said the cathode follower is a buffer stage, no gain. Just tends to make it feel likes it's got more push and headroom.

I own the Maxi - Matcher 2 and the Maxi - Preamp 2 testers. I'll test your tubes for free if you live in the Chicago area.

When the Lead channel and R2 are both engaged there's a little more gain. Similar to my c++'s. I use Mesa Chinese 7025 12ax7's and 415/416's in my Simul's.

I don't need any more c+'s but if I could order one the way I wanted, and it looked old school, I would definitely buy one. The same reason people buy a Gibson Reissue 59 Les Paul. As close to an original as possible

I currently own 5 Mark 3+'s. SRG and DRG No Stripe's. SRG and KDRG Blue Stripe's. And a No Stripe wide DRG that Mike B. had to replace the board. So it's kind of a hybrid. It has the 105 transformer and a later stripe board. They're all awesome amps. The No Stripe's are the closest to a c+. The...

Mesa should open the Bendinelli Lab just like Gibson has the Murphy Lab for reissues. A Custom Shop where you could order any amp from Mesa the way you want, like I did in 1984.

The MS-12 is my favorite speaker to use with a c+. I also have EV's in some of the c+ combos. The EV can be a little sterile and hifi sounding. It adds very little coloration and reproduces pretty much what you put through it. The MS-12 is a little warmer and kinda smears the Mids. They pair...

If Mike B. is doing mods I would send it in before he retires. Just make sure to pack it so it survives the journey. I've sent in a over 15 amps with no problems. I've had Mike upgrade 7 IIc's. Every one came back a better amp. I use 415's/416's in all of my c+'s. The 415 has a balanced tone in...

Sounds good!

Studio Preamp with a 50/50 will get you close to c+.

I have an upgraded HRG++ with the RP11 board. Serial number is 1144x. There could be a thousand IIc's with the Rp11.

Mike B says it's point C of the high voltage rails.

Just pulled the chassis on my upgraded DRG serial number 1235x with the Pull Deep faceplate. It has C+ on the power tube board. Nice catch! I never noticed that before. I'll have to ask Mike B. about that.

I know firefight. I'd give him a faceplate if I had one.

Lies!
