Re: Fake???

That's an early Aidean Zoom copy made in Japan... Also known as a "Meisa". There are alot of em' out there before Mesa got their lawyers mobilzied. They ironically can sound good with a little love... No, this is NOT an Aidean Zoom copy! This is a really old amp that actually predates what became t...

Re: Mark V 90w Midboost

I did this to a Princeton Reverb. In Fender amp with no mids pot you replace the 6.8k resistor on the bass pot with a 100k (or higher) pot. In amps with a 10k or 25k mids pot, just replace it with a 100k pot. From 0-10k it's a regular Fender mids pot. Above 10k it begins to remove the tone stack fr...

My tech (Lowell Amps) recommends pulling the tube as well.
If you did that, the amp would have no sound - V3 and V4 necessary. There is absolutely no need to remove the reverb driver/return tube when using the amp after disconnecting the reverb tank wires.

Re: TC 50 Combo Noise

Hey all, I’m hoping somebody has a similar experience with this so I don’t have to completely disassemble my TC 50 combo amp… The amp makes a noise like tube rattle when I’m playing lower octave notes. It’s a relatively loud noise as I’m playing at about 90 dB and can hear it. At first I thought it...

Re: Replacing Power Tubes in a solo 150w head

Actually by the way things are actually wired in the amp, there is nothing in the power stage that either knows or cares if you arrange your power tubes in symmetrical pairs or not. Let's say your power tubes are three pairs color coded red, green, and blue. One pair of each color. Traditionally yo...

Re: Capacitor replacement on mesa boogie amps

My Roadster is coming up on 12 years old and I have no reason to even consider it. The amp plays great and is played at band volume 4-5 hours every week plus gigs since I got it. These are the years when you reap the rewards of Mesa build quality. Are you having any issues with the amp? If not, don...

Re: Mark IIC++ Hetfield mod

Much of this is true - there is SO much misinformation about the update and mods. Also, correct - it is all in Mike B's head. However, when he "retires" from Mesa, it doesn't mean he won't be doing the work!

Re: Photo request: Mark IIC+ preamp circuit board

Don't even think about putting the tantalum caps in. There is no such thing as a tantalum capacitor that sounds good and when they go bad they become hard shorts. Put in electrolytics instead, best of all, non-polarized ones. Mesa uses those awful tants only because they are cheap and they offer a ...

Re: Royal atlantic head through road king 2x12 cab.

That's a pretty specific setup, those road king cabinets are rare - not because they're special, I think they're just not very popular. Make a new back panel for your Orange cab that's about 1/4 open, it'll take you an afternoon, save you $400, and you can test whether a part-open 2x12 is going to ...

Re: Maintenance For Mark IIC+

A full recap job including the bias caps, plus pot and jack cleaning, and (maybe) new tubes is all it should need. If it's a low hours unit the tubes may all be good but they should still be tested. Be very sure to warn your chosen tech that he can't have your tubes no matter what!!!! Be sure to us...
