I have a very mint condition 410 130 that has been with me for about 8 years. I had a Hamer Daytona for years and it sounded great all of the time. I sold it about 6 months ago and had me a custom Carvin Bolt guitar made to my specs. When I got the guitar after about 2 months I pulled out my MM and it sounded awful!! I tried messing with the controls and everything. I thought something was wrong with the guitar, so I had a guy come over with his setup, a Carvin amplifier, and it sounded awesome. The power was there in the MM but the sound had no definition to it at all. Very muddy, no body. How can this be? All of the Groove tubes lit up, and it is not a power issue. What could cause this problem? I don't want to get rid of my MM because it is a classic. Do I need new tens? ON the Carvin board several people have told me that the MM amps don't mix well with the Carvin guitars. I don't personally don't see how that can be, but maybe I am wrong. If you think I need new 10's what kind? Celestion? IT has the alnico in it now. Any help is certainly appreciated!! | ||

It might be more probable that the amp needs a "cap job" (where all the electrolytic caps are replaced as these dry out after 10 or 15 years) or new output tubes or both! I don't think your speakers would be the main culprit without first plugging in another cabinet and see if it still sounds similar. Steve | ||

I agree with Steve. Also, mine needed a new output transformer. It tightened up the sound and got the "bark" back into the thing. | ||

OK then As mentioned before I am an auto mechanic by trade. I would love to be able to do this work myself instead of paying someone. I have a fluke meter and have built myself a capacitor "tool" for discharging. I want to go with JJ E34L tubes. Is there any place I can go to learn, or is it just trial by error? I dont want to hurt the amp, but I really would like to learn this stuff. Also, what kind of board is in use on this amp/ thanks in advance I mean to learn about biasing etc... Michael Michael | ||

You could attend one of Gerald Weber's (Kendrick Amps) Tube Amp Seminars for about $500, if one is held near you: Denver, Co May 14 Kempner, TX May 21 (AMP CAMP) Baltimore, MD May 28 Albany,NY June 4 Minneapolis/St Paul June 11 Cincinnati,OH June 18th Salt Lake City, UT June 25th Milwaukee,WI July 9th Vancouver, BC July 16th Indianapolis, IN July 23 Boston, MA July 30 Detroit, MI August 6 Newark, NJ August 13 Kempner, TX August 20 th (AMP CAMP) Hartford,CT August 27th Chicago, IL Sept 3 Atlanta, GA Sept 10th Nashville, TN Sept 17 St Louis, MO Sept 24 Philadelphia, PA Oct 1 Charlotte, NC Oct 8 Long Island, NY Oct 15 Portland, OR Oct 22 Okalahoma City, OK Oct 29 Las Vegas, NV Nov 5 Shreveport, LA Nov 12 Kempner, TX Nov 19 (AMP CAMP) If interested, check out his web site at: Kendrick Amplifiers This is the only place I can think of where you can get right to the meat of things without taking a complete electronics course. However, Gerald also offers a number of books, tapes and a new DVD that covers all the basics of tube amp overhauling and maintenance that might be a good investment.
