The Boogie Board

Shortly after I took up the guitar I realized that I simply had no interest in practicing enough to ever get good enough at it to make any money. And that never stopped me from acquiring more gear and more guitars and making many guitars. Today in my 50s I restore vintage Marshalls to a level that l...

I work from home, being an ebayer with access to a pretty consistent yet diverse range of products to market, and don't have any compelling need to leave home for more than maybe two trips a week if I combine my trips. Pick up product to sell, ship product to sell, make a small grocery run once in a...

It's an extensive mod. The PC boards are very different between a B and a C.

That's going to be a tall order to fill. Might I suggest that you contact Mesa or Sour Mash and have them make you just what you want here?

I'll probably be faster, cheaper, and easier to have them make you a new one as you want it.

Contact Sour Mash cabinets and Bob will make you the headshell you want. Or you can get one direct from Mesa. It's not a tough project. I've made one or two. (Not looking for work making any, sorry.) Any decent woodworker should be able to make a nice headshell cabinet. If he has a finger jointing o...

You might try installing Tung-Sol 7581a power tubes. They have increased power handling and headroom capacity, 35 watts per tube rather than 25 per tube for a 6L6. If your amp has the power delivery capacity then you're going to reach 70 watts per channel before tube clipping. Be careful when changi...

You can just use weatherstripping foam. It's not super critical, as long as it holds well and is non conductive.

You could even contact Mesa and have them send you a piece of what they use.

Look on the outside of the chassis where the EQ board is. See any hardware? If there's none, then the board is just attached with double sided foam tape. Carefully cut through it, pull the board out, replace the caps, and take extra time and care to remove ALL the old tape before reattaching it with...

Sure enough, it was the 500 pF ceramic disc treble cap. Just replaced that, and while I was at it, gave it a new set of filter caps, and it's running great again.

Don't mess with it. Take it directly to a qualified amp tech and let him handle it.

Any other advice is wrong.

On second thought, it's probably a leaky treble cap. 800 pF. I don't have that value on hand so I ordered up a few.

So I was playing my 3 channel dual rec this evening, went to take a break, came back, and found that during my brief absence something had failed. In the orange channel, the treble control has stopped working correctly and is now working incorrectly. As the treble control is turned up, the output le...

Well, I know to never use THAT image hosting service! The images still haven't fully loaded and it's been several minutes! What are they on, a 300 baud dial-up connection? That's just absurdly bad data transfer rates right there. Those caps are so old, it'd be a crime not to change them. And if any ...

I see no photos or even broken links. My browser usually sees those things just fine. Burned resistors are always signs of other things that have failed and drawn too much current. If the amp has sat for 10 years, yes, it should be recapped. Letting them sit with no charge on them is literally the w...

Check with Bob at Sour Mash Cabs. He makes some of the best cabinets in the business. If he has the data on the cab you need, he can build it, and almost certainly cheaper than Mesa and he'll do at least as good a job. His pricing is such that I don't bother to build cabinets myself anymore. I call ...
