Re: Mark III Red Stripe Combo Graphic EQ and Reverb

Take it to a qualified amp tech. It is probably a mode switching problem.

As long as it's there, see how old the power supply capacitors are. Odds are that they've never been changed, which means THEY'RE DUE. Change them before they fail and take out a transformer.

Re: What's your fave speaker?

EVM-12Ls for Mesas (and sometimes good for most any amp) and Celestion Greenbacks and (reissue) Creambacks for anything related to a Marshall for sure. My favorite cab setup is two Greenbacks and two Creambacks in a Marshall 1960A cabinet.

Re: Mesa Amp Etiquette - Good habits ?

Tube lifespan is determined by operating hours and operating conditions. If you gigged three nights a week, you MIGHT need to change power tubes once a year. So....at your current schedule you can assume that unless there's a failure you'll never need to change a tube. Filter capacitors, though, las...

Re: So, what amps do you own?

I've made several changes since last time I posted. My latest acquisition is a Marshall JTM45 head. (First reissue, late 90s.) The Twin Reverb and the Super Twin Reverb are gone. I added a Blackstar JJN20 head which is a LOT of fun. The Marshall DSL100 and MA50 and MG100HCFX half stacks are gone.

Original style Boogie EQ knobs, 4 available

I have a stash of four very good condition original EQ knobs for your Boogie's equalizer. Price is 10 dollars each plus first class mail cost. If you want to upgrade to priority mail, that can be done as well. These are no longer available from Mesa. They have a replacement but it's different. PM me...

Re: Flight case for Mark II head

Contact Mesa for recommendations. I'm sure they know who makes good road cases and who makes bad ones. Is this for a combo or a head? Be aware, price ranges can double for any given case when going from the most basic case to the most deluxe case in the same brand. Now how exactly does UPS manage to...

Re: Farewell, 4x12. Farewell, dreams of youth...

You don't have to give up the big rigs just because you're not young or not gigging anymore. I got my first two 4x12s at the age of 53. At the age of 54 I got my first two Marshall 4x12s and first FIVE 100 watt Marshall heads from the 1970s. Now I'm 55 and I have even more. My practice sessions almo...

Re: Mark II C+ HX Head.

Just FYI, if you set the export transformer voltage to the 100 volt setting and plug the amp into 120 volts, this will result in too much voltage getting into the circuitry. This is the exact opposite of sagged voltage as you wrote. You'll over-voltage the amp by about 20 percent by doing that. That...

Re: Help needed choosing a poweramp for a Studio Preamp.

You want a Stereo Simul-Class 2:90 or Stereo Simul-Class 295. They have power amp topologies that are basically identical to that of the Mark IIC+.

Re: WTB: Emtpy Head for Mark 1

Mesa can make one for you. Sour Mash Cabs can make one for you. It's only a medium skill leve woodworking project, and any decent woodworker who has a router and a dovetail fixture can knock one out for you pretty quickly. (Dovetails for a hardwood cabinet, I recommend finger jointed for a ply cabin...

Re: Triple Rect (Pre Wattage Selection)-Issues

Some versions use J175 FETs for switching. They can go flaky. If that happens, the best solution is to replace them all at once.

Your Recto is the world's best tube tester.

Yes, it really is. The V1 socket is both the input for the whole amp and also the clean (green) stage channel. It has the highest gain per stage of any stage in the amp, with 220K plate resistors. (Also true of V3A, which feeds the cathode follower that is V3B.) The value of the plate resistor is th...

Re: Unbelievable tube score

I recently scored two separate pairs of (apparently) new in box Sylvania STR-387s. One pair has single getters, the other, double. But I can't test them because right now my tube tester is undergoing an overhaul.

Re: The Ultimate Boogie rig.

That is a VERY nice setup indeed. Well done! If I wanted to build a setup like that, I'd probably build that except that I'd use a Fractal Axe-FX II or III (III preferred) as my effects unit, with the ability to bypass the other preamps and be able to exploit what the Axe-FX has to offer in the way ...
