Before starting, I must warn you that acquiring vintage gear can be really risky.You can end up buying something that is not what you expected or even something that is damaged or modded beyond repair.Please note the “Black Flag” JTM marking that was used at that time.The JTM-100, now with four EL-34s too, also gained a proper 100w transformer. It was called Marshall Super Lead 100w #1959 (Although they still didn’t have the “JMP” mark on the front, In my view, this amps are already into the JMP territory, because they have all of the JMP characteristics). This early “Plexi” versions (up to 1968) are really articulate and have a real nice “roar”.Here are some of them: Marshall Bass and Super Bass Back of a Marshall Super Bass The Marshall Bass 50w #1986 and the Marshall Super Bass 100w #1992 appeared after the change to the EL-34 tubes. These amps were not only stupidly loud, but also really really clean.Related to the #1987 and the #1959 respectively, they were designed for bass players. It’s 200W of pure loudness The Marshall Major 200w has a different circuit than its “little brothers”: the pre-amp has two ECC83s, but the third tube (the “driver tube”) is an ECC82 (a.k.a. Ritchie Blackmore was a famous user of the Major, but they were heavily modded at the Marshall factory (as said in an interview) and later by a man called John Dawk. These amps also CAN NOT TAKE ANY KIND OF BOOST OR OVERDRIVE. These amps would blow because they were already working at critical point without anything, so if you plugged something to make them run even hotter… This is one of the reasons why the Major was discontinued in 1974. Note: 8 knobs instead of 6 These amps had an extra 12ax7 tube for the “tremolo” effect.You may now see our list and photos of women who are in your area and meet your preferences.

Marshall then “hot-rodded” the JTM-45 using four KT66 and two 50w output transformers to handle the extra wattage. The result was the JTM-45/100 (JTM-100, for short).With more power tubes, the amp had more headroom, a tighter bass response and more definition.It was the first Marshall with a solid state rectifier.If you're looking to get in touch with us, please contact us at: Marshall Amplification plc, Denbigh Road, Bletchley, Milton Keynes, MK1 1DQ You can contact us on 01908 375411 or for any other query please email: [email protected] queries related to your speakers or headphones please head to: order for us to effectively deal with your request, you must let us know your name, email address, daytime telephone and country.If your enquiry is related to a product you own, please include the model and serial number to help us deal with your issue.

So, always keep your eyes open for “fishy” deals, look for information, and always ask for high definition photos (especially from the interior of the amps – the circuit, the tubes and transformers) to make sure everything is right.
