Tips and How-To’s Marshall amplifiers made hard rock possible. While Fender and Vox amps have their place in moving electrified guitar forward, the creations of Jim Marshall fostered an entirely new sound and allowed guitarists to fill stadiums with it. Marshall amps had such precedent-setting wattage and tone that their history can hardly be separated from the history of rock itself. We recently wrote an article detailing that rich history which you can read here , but for those simply looking to figure out how old their Marshall amp is, we offer this shortcut. The guide below will help you quickly and clearly date Marshall amps and cabinets, without us waxing poetic about their influence.

History[ edit ] The 5B6 Bassman[ edit ] During , the Fender 5B6 Bassman amplifier was introduced as a combo amplifier cabinet that included the amplifier chassis combined with one 15″ speaker. It was designed to generate 26 watts at an 8 ohm impedance load, and offered a cathode-based bias. In the cabinet designs were changed to the so-called “Wide Panel” design, with a 5 inch wide tweed covered panel above and below a wider swath of grill cloth.
Fender ceased production of 5B6 Bassman amplifiers during the spring of The 5D6 was a major departure from the earlier 5B6 Fender Bassman model. The circuit had two innovations: No schematic for the 5D6 circuit has ever been found, but Ken Fox and Frank Roy have created a few from originals, and copies are freely available online.
Only 11 of these early 5D6 Bassman examples are known to have survived. Narrow panel models, to [ edit ] Fender began making other models with tweed covering, a similar open backed cabinet with a rectangular grill cloth and a narrow just over an inch wide tweed covered panel at the top and bottom. Produced from until , these models are called the “narrow panel” tweed amps.

A bell rung morning, noon and night as a call to recite the Angelus Prayer to commemorate the Annunciation as follows: The rounded part of the clapper containing the largest concentration of mass which strikes the bell at the sound bow level.
A History Of Marshall Amps: Part I. Published you can get a full breakdown of serial number dating and speaker codes for Marshall amps in our Marshall Dating Guide. The JTM – At the time, it was said that Marshall had created the “world’s first great bad amplifier.” Unlike their contemporaries, Marshall amps had distortion.
The source-date code on a pot is a 6 or 7 digit code impressed into the casing of the potentiometer. For speakers this code can be 5, 6, 7 or 8 digits long, and it’s ink-stamped or paint-stamped on the “bell housing” of the speaker. In either case, the code works the same. The first 3 digits on a pot, or the first 2, 3 or 4 digits on a speaker are the source or manufacturer code. The remaining 3 or 4 digits are the date code.
In 3 digit dates code, the 1st digit is the last digit of the year. On 4 digits date codes, the 1st and 2nd digits are the last two digits of the year. In either case, the remaining 2 digits are the week of manufacture 01 to With this in mind, remember if the last two digits of the source-date code are greater than 52, you’re not looking at the source-date code!
Also it’s worth mentioning: On 3 digit date codes, you have to “guess” the decade of the pot or speaker. Usually this isn’t too difficult. Examples of Source-Date Codes. With all this information in mind, can you identify the following manufacturer and date of these source-date codes?

Many of these brand names are but a faint memory today, while others have garnered attention bordering on hysteria, thanks to eBay. One of those names was Stark. What little I know personally about the company called Stark is as follows. Stark was an electronics manufacturer located in Ajax, Ontario during the golden days of radio.
It appears that Stark actually manufactured their own test equipment, including the earliest tube testers. The earliest Stark tube tester is probably the Model
Marshall Amplifier Date Codes There are easy ways to determine date of your Marshall amplifier’s manufacture by the serial number. The charts below will explain how to read the serial numbers and decode the model numbers.
Features one channel and two inputs; volume, bright, treble, treble expander, bass, bass expander, bright switch, deep switch, stand-by switch, pilot light for stand-by and operate. This amp was built to play larger halls and outdoor concerts. The lack of reverb was not a big issue as most live performances had acoustics full of reverberation halls, arenas. Peter Traynor built these things to stand up to road abuse, unlike a lot of vintage stuff. It sounds great with either bass and guitar, providing a clean and loud tone.
Works great in large club settings. Front panel has two input jacks, controls for treble boost, volume, treble expander, treble, bass expander, bass, presence, and bass boost. There is also a standby switch and corresponding green and red pilot lights. There are no effects in this head, but stomp boxes work just fine. The front of the amp is wrapped in a Fender-style silver-face cloth [ There is also a cooling fan installed. With tubes, you’ll get about W from the Custom Special.

MCM vs SiP vs. Computer and communication companies have driven this trend for decades through finer lithography, better materials, and larger chips and wafers, all leading to higher clock frequency. Cost was not a factor. But the world has changed, and the primary focus today is more functionality at an affordable cost. Even personal computer companies have moved on to dual- and multi-core processors that perform multiple functions on a single chip — spreadsheet on one quarter of the screen, photograph editing on another, watching a movie on the third, and video-conferencing on the fourth.
The key challenges to SoC progress, however, are formidable, and include design and design verification, manufacturability, intellectual property IP and legal issues, time-to-market, and cost. To overcome these problems, system companies pursued a different approach to SoC, dating back to the s. Instead of integrating all or most of the system needs on large and complex single chips, they fabricated smaller, high-yielding chips and reconstituted them to behave like large chips as multi-chip modules MCMs.
MCMs saved the computing era back then, even though they were capital-intensive and technology-complex. They still offered a better solution than SoCs by interconnecting dozens of chips in a small, horizontal form factor for high signal speed. This required a different approach to IC and component packaging, and led the industry to 3-D chip stacking of either bare chips or packaged chips. Since both required interconnections from chip-to-chip, packaging was a critical technology element.
This kind of approach was referred to as systems-in-package SiP.
Pilot Electric Manufacturing Company also claimed to be “The World’s Largest Radio Parts Plant” in the twenties and they did build all of the parts supplied with their kits.

While the age of an amp has no bearing on how good or bad it sounds, it can have an impact on the selling or purchase price of a Marshall rig. Using the information in this section, you can attempt to dial in the possible dates of manufacture more closely than by sheer estimation alone. Does it have a bar code? Yes read on No scroll down to the seriel nuber section Marshall began using a nine-digit bar code label beginning in If your amp or speaker enclosure sports a black-ink-on-white-background barcode label on the chassis or back of the cabinet, then you know that the product was manufactured somewhere between and the present.
MARSHALL DATE CODES Early Marshall through the JCM series. July of Marshall introduced the date coding system. Some of the older amps have an inspection sticker on the top of the chassis and they usually have the day, month and year the amp was made or inspected.

This is probably the biggest area of confusion when dating Marshall amps. True serial numbers weren’t really used by Marshall until July , so specimens made prior to that can only be accurately dated to a fuzzy span of several years.
Still, the song that brings out the enthusiastic grin on most of us is of course Dogs. For me it was what got me into this crazy hobby — trying to figure out how the hell David got his magical tone. Dogs dates back to the middle of the Dark Side of the Moon tour. Pink Floyd had been performing Dark Side in its entirety since early — a whole year before the album was released and as they kept on adding new dates to the tour they badly needed new material.
David wrote most of the music later stated that he was particularly proud of the chord progression. The earliest version even had a long choir part in the middle section, similar to what David and Richard used to do on the 4-piece live version of Atom. Throughout the tour Roger would rewrite the lyrics several times as David found it too hard to sing — there were just too many words Musician, August Sheep and Dogs revealed a heavier side of Pink Floyd.
Although the band never fully entered the prog rock scene they used elements in their compositions blending it with their deep roots in blues and jazz. There are two tracks paned to each side.
