The first three digits indicate the jbl for the speakers. The date indicates Altec Lansing and represents Harman Kardon. Look at the remaining digits. The first two horn after the manufacturer three digit code indicate the year. Speakers made for the s only have one digit representing the year which is misleading. The remaining digits indicate the jbl of that year. For horn, a earphones of indicates that the speakers were made in the 22nd week of by Harman Kardon.

Wayne, Indiana. That amp worked pretty well with my Rick string. That amp turned out to be an early-production Pro-Amp. I started to investigate the world of pre-CBS Fender amplifiers.

Code formats were not completely standardized, but a little deciphering will generally yield the info of interest. Note that many makers also stamped OEM Original Eqipment Manufacturer part numbers above or below the EIA code, in some cases parts makers or the customer elected not to include the EIA codes, so not all parts have them. They generally follow the following format: example where is the manufacturer code in this case CTS , 59 is the year , and 04 is the week. Usually single digit date codes are from the ‘s, but have on occasion shown up in later decades, even up to the ‘s.
If one has a general idea of the age of the piece in question, usually the decade can be divined from that. Another alternate is in the format following: 69 32 is General Electric. And another is like this: is CTS, is , 4th week, 1 is the shift code 1 would probably be the day shift.

Possible culprits include the preamp tubes, the power tubes, the hum balance resistors, and the power supply caps. Thanks for your input. I have a Deluxe Reverb and am trying to figure out if it has a Utah or some other kind of speaker. Any speaker ideas on that front? I also have one of the newer Fender Pro Reverb amps with an effects loop and a silverface Twin Reverb with a volume control. Both amps produce very loud hum whether or not a guitar is plugged in.

May 18, 1. May 22, austin,tx. It’s an 8ohm, 15″ square magnet with the following numbers. Can’t find anything on the 15G54B though. It is a bass or PA speaker, vented dustcap and feels like there’s some excursion to when you push on the cone as compared to a guitar speaker for example. According to that link there’s a possibility it may have come from and old B15, can’t be sure though.
Sorry, can’t do pics. Anybody have any other research links or a B15 with a similair CTS perhaps? May 18, 2. Used them too they are fine speakers they are in some of the cabs and cabs. So if you don’t hate Jaco’s sound you have a bargain.

I know, I know. For those readers who may have joined us recently, I am doing some Fender amp research along with Devin Riebe and Greg Huntington. Our research efforts are now in their fourth year will it ever end? Again, I would like to thank everyone who responded to our request for data as outlined in Parts 1 and 2. Early silver face amps: Part 2 went into this topic in some detail, but since that article was printed, I have been asked a lot of questions about this subject.
Part of the confusion stems from the lack of any AB or AC tube charts. Fender never printed any since there were plenty of leftover AB tube charts available and these were used well into Although the cosmetics changed, the circuits remained unaltered from the blackface circuits on the earliest silverface amps. The date of the change from the blackface circuit to the CBS silverface circuit was dependent on the model, but most of the amps that were modified received the circuit change by mid-year of The cosmetics of the silverface amps during the transition between circuits was also in transition making it difficult to determine circuit type on cosmetics alone.

Fender Tube amp codes: – look for a 2 letter code stamped on the tube chart inside the back of the amp – the first letter is the year, and the second letter is the month. An amp stamped NA would have been made in Jan. Here is a list of the first letter showing the year of manufacture.

However we’ve seen early year SVT’s without any hand numbering. Both versions have been seen throughout In Ampeg manufactured three different types of removable back panels for the SVT. The serial number was stamped into the right side of the back panel. This version was chrome, still with white silkscreening and serial number stamped into the right side.
By October serial numbers began to be stamped into the chassis, between the standby switch and the external amp jack. Leftover units at the end of used the xxx prefix, January started at xxx, Feb xxx, March xxx, April xxx, May xxx, June xxx, July xxx, August xxx, September xxx, October xxx, November xxx and December xxx. The SVT was introduced in June , therefore the first units should have an xxx serial number.
On vintage SVT’s, the newest date code on the unit is usually the four digit white ink stamp on the large output transformer. The first two numbers indicate the year, the third and fourth numbers indicate the production week of that year. Other codes to determine the manufacture date: The other large power transformer and the adjacent smaller filament transformer usually have six digit codes stamped into the metal.
The first three digits indicate the company’s personal manufacturing code.

The Twin was introduced in , two years before Fender began selling Stratocaster electric guitars. The amps are known for their characteristically clean tone. The Twin has seen a number of revisions since its introduction, both internal and external, with its designs sometimes varying greatly from one year to the next. The Cyber Twin, which combined a tube amp with a digital processor, was introduced in January The Fender Twin has gone through a number of changes over the years, both cosmetically and electronically.
The original version was an all-tube combo amplifier with dual 12″ speakers and two 6L6 tubes for a rated output of 25 watts. The early models of the larger “narrow-panel” tweeds are also remarkable for their refined electronics whose circuit design incorporated dual 5U4 rectifiers in the Twin and Bassman models, another improvement given Fender’s quest for a louder, cleaner amplifier.
The entire line of Fender amplifiers from to later for smaller models and Bassman was uniform in this look—tweed or “airline linen” covering with a maroon with gold stripe woven saran grill cloth. By the end of the decade, a JBL 15″ speaker was available on special order for the Pro model. It was modified in for more volume, switching to four power tubes  with the more efficient long-tailed pair phase inverter for a power increase to 80W.
This “hi-powered,” tweed-covered design continued into early , after the other Professional Series of Fender amplifiers had made the transition to the modern brownface design. The upgraded 5F8 Twin-amp of with its complement of four military grade ‘s was briefly rectified with a tall mercury vapor 83 tube and special tube socket.
Due to its volatile nature if broken, it was quickly superseded with a GZ34 rectifier but not duly noted on the tube chart until the second production.
