Apologies BB. I mis-read your board status as your board name. Long day. But out of curiosity, I read up on the Road King. How did they keep the circuit boards from baking?? Cool concept for a touring rig though.

Thanks Roadking. That exactly the kind of first hand info I was seeking.

Also, I just remembered that the effects send/return jacks can get intermittent contact and cause issues. You can carefully clean those contacts with some DeOxit on a cotton swab, or just spray some cleaner on cable jack and cycle it through the jacks, cleaning off any deposits from the cable...

The jacks in the middle of the chassis are the pre-amp send/power-amp return and the reverb/graphic pedal jack (single stereo jack). Do you have the Reverb/Graphic stomp box? You may want to read the original Mk2C manual that Mesa Boogie included with the amps. I think this document is...

Tube pins can pick up micro corrosion from the heating and cooling effect pulling in moisture. I live by the ocean, and the salt air adds another component to the equation. So, I clean the tube pins on my amps a couple of times a year. Caig DeOxit Gold is an excellent product for this and it...

I really appreciate this board. You guys have kept me on track more than once. On the subject of caps for the DRG, is there any preference these days? There are so many new choices today, like F&T, which I have used in other amps successfully. The 30u/500v cap they make is a little bit large...

Thanks BoogieBabies... I just got back from my shop where I was doing some more testing with the amp on the bench. Your information is right on the money. It was great to read that what I was seeing on the meter is in the ballpark. Also, the voltages while playing the amp were different in...

Hi everyone- I was just wondering if anyone here might have specs for the MkII C/C+ power transformer, 100-162318. I have searched around the forum, but didn't find what I needed. I have looked at Boogiebabies excellent thread "MkIIC+ Guide for Dummies" thread, which indicates my DRG IIC...

Hello Dasein- Probably years of dust in the chassis, but then again... The amp may need a full refreshing of all the electrolytic capacitors. Electrolytics don't like to sit unused for years on end. They need to be used regularly to be at their best. Even with continual use, they won't last...

Thanks Stokes. I was just wondering if these original caps were an audio grade cap or if they were just general purpose elytics. They might be a French made cap as they have "CE" on them, but that's a guess. The one 10uf is just a local reservoir that helps hold up the power rail. The other...

I have a Mk II C that has had the '+' upgrade. Mine has the RP11A pre-amp board. Yours might be different. That said, on mine, in back corner of my 11A board, underneath the high voltage supply board, is where the footswitch/LED power supply section is located. It consists of the input from...

Greetings all- My '83 Mk II C Simul (DRG upgraded to C+) is needing to be re-capped. Not a major issue, but I got to looking at the electrolytics on the Grapic EQ amp board and I can see that the 10uf/63v caps are looking puffy. Is there anything particularly special about these e'lytics? I...

Hi everyone- I'm an occasional lurker. Really enjoy reading the posts on the vintage Marks. Just a quick history about my amp: I've got a late '83 Mk II C (ser # 12009) that was given the free C+ upgrade by Mike and the gang back in early '84. When I knew I wanted a Boogie, I came up to...

Hi Pigwings- Filter caps and any other HV electrolytic caps and, to a lesser degree, rectifier diodes all need to be watched on older amps. Check to see if the caps look "puffy" on the ends. You also can get faster acting diodes to minimize ripple on the power supply. I changed all of this on...

SED EL34's? Yes yes yes!!! I just started using them a few years ago. Great for that tight, focused, shimmering sound. Yeah, I was pretty jazzed when I started using those in my IIC+. They are a bit louder than the 6L6 variants, I think. I just went back to 5881's for a more classic...

Ahhh... yeah... know what you mean. The key is to TURN IT UP! It needs to flesh out. I usually dial the bass up 1 notch too when in class A. But if you run 5881's in class A mode, you get a nice dark compression. I run the master at about 3 and vol 1 about 7 or 8 with a lester. 10 with a...

Thanks RussB... are you liking the T.A.D.'s overall? How do they compare to say a JJ or a Svet? I was thinking about running the small bottles in the outside pair of my Simul and maybe the big bottles in the center. What do you think? Best, Allen

Good Gawd Magnum!! Running the master at 9??? Robin Master's Ferrari at 180 MPH??? Zeus... Apollo... KILL!!!! Sounds like a good time to experiment... heh heh... I have tried the 454 (yellow) in class A... liked the 5881's (blue) better. More headroom with the 454's as you would expect...

cool. glad to at least hear a credible opinion on how they work in guitar amps. What do you like about them? How would they sonically compare to say a STR-454 (Svet) or JJ 6L6GC? Have you ever used those short body T.A.D.'s? I was kinda looking at those... Thanks, Allen

Wow! Amazing. Just goes to show ya! I LOVE the "class-A" setting. I pretty much leave it there exclusively. And I definitely go for more power tube saturation using either 5881's for blues or EL 34's for rock gigs. Sure is a versatile little amp though, huh? Back when I first got the amp...
