Re: Opinions on a ‘95 Triple Rec

It's always been my understanding that Mesa has basically only ever had ONE output transformer for ALL 150 watt/six output tube amps. The OT in the D180 I had appeared to be identical to the OT in my first gen TRS head. It's supposed to be the same one used in EVERY Coliseum head. Given the cost of ...

Re: Where to get Mesa OEM tolex and grill cloth?

If I have a known set of good dimensions to work from, I'll MAKE you a new grill frame and cover it in the grill cloth of your choice for a very reasonable price. The best way to proceed is for you to take your grill off and measure and photograph it front and rear and send that info to me. The more...

FS: Set of four Celestion G12P-80s (Same as 70/80)

I just pulled a pristine set of Hartke labelled Celestion G12P-80s out of my Hartke 412A angled cabinet and replaced them with a set of broken in reissue Greenbacks. So, these G12P-80s need a home. I don't think they're bad sounding speakers. They just don't sound like Greenbacks. They're brighter s...

Re: Mark IV with 6V6 - Triode? Pentode?

The pentode/triode switch doesn't change plate voltage. It just determines how the screen is connected in the circuit.

You can mess with that switch with 6V6 tubes installed. Just don't do what it says NOT to do.

Re: Mark IV with 6V6 - Triode? Pentode?

Use 6V6 tubes ONLY when TWEED and SIMUL-CLASS are selected. Just like it says.

If you use any other mode, you're going to blow up the tubes. 6V6 tubes are limited in the voltages they can withstand.
In any other mode, the amp will over-voltage a 6V6.

Re: So, what amps do you own?

I've added a "fixer upper" 1972 Fender Twin Reverb to my collection in the last few days. It had the wrong output transformer (had one from a reissue Twin, which physically is different and doesn't quite fit) so I got a correct one. A little work has gone into the amp but it's running. Now I have to...

Re: Will Mesa build...?

I'm in Florida. There's got to be someone you know who's a woodworker. Or...is there a college or vo-tech institution in your area that has a woodworking program or wood shop of some description? You could sign up for it and learn to make your own cabinets and maybe even get busy and make a bunch us...

Re: Will Mesa build...?

Guitar speaker cabinets are not exactly advanced level woodworking projects. Have you considered having your friend the woodworker build you one? Shipping costs make it impractical for me to build big cabinets like 4x12s for other people and ship them, but for local musicans I've built a small numbe...

Re: White noise.

Voltages are higher, gain is higher. The amp is more sensitive, responsive, and dynamic. What you report should not be unexpected.

How is it with the pedals NOT in the loop?

You may have to adjust a few parameters to compensate for the effects of freshening the amp.

Re: Studio. 22 speaker upgrade battle

I've found very good condition lightly used EVs for a hundred bucks and that's pretty cheap. It's in your budget if you decide to wait and save just a little longer.

Re: Using a 12at7 in place of 12ax7 in dual rectifier

At a certain amount of gain the amp will start sounding fizzy. A lower gain tube will simply allow you to turn the gain knob farther before you reach that fizzy spot. I've done some tube swap experiments and have certainly heard subtle variations in the overall sound of the amp in addition to the ga...

Re: New Fender Amps..

I think Fender made a commendable effort with the reissues they've put out lately but in my opinion they miss the mark. I would suggest that in many cases you can get a clean original example for less than the cost of a new "reissue" that doesn't quite capture the tone of the original. Have that ori...
