Mechanical Details and Variations Piano Actions Pre Seeburg pianos typically have no stop rail to limit the travel of the stack pneumatics, neither on the stack nor on the piano action. Post pianos have a stop rail on the piano action, allowing the pneumatics to have a little extra span and providing for manual adjustment of the stop position of each pneumatic. Pneumatic Stacks Seeburg numbered its pneumatic stacks with steel die stamps, starting in and ending sometime in In the first series, known numbers run from through Probably after , a new numbering series was begun, usually stamped in smaller numbers, with known numbers from through , then a large gap, and then one much higher number, The new numbering series does not necessarily begin with the late style two-tier stack design, but more information is needed to pinpoint the change. Seeburg made five types of pneumatic stacks: Single valves, no adjustable bleeds. All valves are installed in one vertical valve box on the front, with removable inside wooden seats, each seat holding four valves, except the last one, which has fewer. Each valve is mounted on a small wooden lever that is guided by a tiny steel pin.

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.

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.

Of course, music has always been an international art form that connects people around the world. Avi Goldfinger, a guitarist and singer-songwriter, is the third partner. Conducting meticulous studies of heritage guitars dating back to the s through s, they are striving to gain insights into the formula that has established these instruments as timeless classics.

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. Though not the first Shortwave receiver kit offered by Pilot, the three-tube “Wasp” was certainly their first really popular Shortwave receiver kit. The plug-in coils selected the tuning ranges that covered meters to 17 meters or about kc up to A complete coil set featured five coils each with color-coded handles for identification.
The three tubes were usually A and the circuit used a regenerative detector followed by two stages of transformer coupled AF amplification. The kit included detailed instructions along with an assembly drawing. Builders were warned to adhere to the wiring layout shown on the drawing or performance would suffer. The circuit was built on a bakelite board for the chassis and a mahogany colored bakelite panel.

Previously Rzeznik had been in a band with Takac’s cousin, called The Beaumonts. In the early days of The Goo Goo Dolls , the band performed at gigs relentlessly, with Takac as the frontman Rzeznik gradually becoming the frontman over the next few albums, as each new album contained more songs sung by Rzeznik than the last. They were soon picked up by a small record label, Celluloid. This attracted the attention of a larger record label, Metal Blade , who released their next few albums.
All Marshall amps originally came with Celestion speakers, so in cases where the speakers are original, speaker date codes can be used to date earlier amps. Marshall cabinets didn’t officially include serial numbers until October As a result, dating cabs can be more art than science.
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 An example is seen below. Early example of Stark tube tester. The small chart affixed to the top lid lists the tube types that can be tested. What you may note is that there is a very limited switching array, and the tester itself is very small and compact. Now things get very confusing. Another theory has it that certain tube testers were shipped as parts into Canada, and assembled.
This would help eliminate import tariffs, as the tube tester is now manufactured in Canada! The circuit inside was the standard Hickok fare; an 80 yielded unfiltered DC for the plate voltage supply, while a 5Y3 gave unfiltered DC for the screen grid and bias voltages.

These amplifiers both feature the basic JTM 45 modified Fender Bassman circuit, which provided the origin of what became known as the “Marshall sound”. The first versions of these combo amplifiers were made in –, with Models and being .
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. The 5E6-A Bassman model was introduced later that year and included some evolutionary improvements. By the middle of more than 1, examples of the 5E6 series had been sold.

Please don’t ask if we know any other speakers than mentioned on this page. When you know the best, you’re not interested in the rest. No, we don’t know if your Speakers match your Amp, but we can tell you how to tell if they are below. The more amps we try on our Tannoy Golds, the wider our opinion can be. The fact is there really is no way to tell beyond actually trying the Amp with the Speaker. We’ve not got bigger speakers of the post design, if we use some small ones to test, they hardly give a full picture of the sound.
Buying a Speaker is the most hard of all hifi items to buy due to the huge tonal differences and how they interact with the room you use as well as the amplifier. Phase errors will create a poor sound as well as the minute volume differences. The Human Ear cannot supposedly hear these differences, yet some state we need Amplifiers delivering “sound” beyond 20 kHz to have music sounding right.
A speaker in a room sounds less upfront than having two small desktop speakers on the Computer inches away.

According to an article on gibson. In this video, he can be seen playing the intro to “Red House” on this guitar. The Flying V has a black finish and gold hardware, and diamond inlays instead of the usual dots. Original source article here. It was one of the guitars that he had the longest, it stayed with him several years. He called the guitar “Betty Jean” after his girlfriend, and left the guitar with her mother when he went off to the Army in Epiphone writes “though many of the early Epiphone instruments made in Kalamazoo were under-appreciated at the time of their release, numerous artists through the years recognized the unique appeal of these guitars including Jimi Hendrix, Johnny Winter, Kurt Cobain, and Steve Marriot.
If it ever surfaces at auction, expect a stampede of hedge-fund managers. Knight got the guitar in exchange for refunding an airline ticket for a friend. Jimi played this guitar with Curtis Knight and the Squires. The guitar must have been an exceptional instrument, because Jimi kept it with for for the rest of his career.
