New England pchilson said: I can’t find any informative code on the PT that I can use for manufacturer or date, only the “TR 88″ shown in post 12 and that doesn’t align with any manufacture code as far as I can tell. The OT is not original so that doesn’t tell any stories. The volume pot code is ” ” made by CentraLab dated Oct. So the amp dates at least to I don’t know if I mentioned yet but the schematic was pasted to the chassis bottom cover plate, it states this on the chassis itself but that cover was not with the amp. I cannot find nary a mention of this amp anywhere. I’ve seen mention of being able to go to the library and somtimes being able to find old service manuals with schematics in them. Anyone have ever done that? Any tips on how I might track down a schematic?

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.
Code on the pots indicate CTS brand from the 30th week of The below Les Paul Special wiring shows correct “bumblebee” capacitors and braided pickup wire. The codes are on the sides of these pots () and indicate CentraLab brand from the 43rd week of

Gibson Les Paul Junior solidbody guitar Available: Originally sold as Gibson’s least expensive, single pickup, student solid body model it was replaced as the least expensive solidbody Gibson in by the Melody Maker.

The SD-9 with two circuit boards (one is down with the pots) has less oscillation problems when you turn it up high, so I prefer modifying those types. Also the Maxon has .
Gibson Vintage Reissue Electric Guitar Strings Hi, Your bass is an SB – short scale – the long scale ones had their bridge slightly beyond the tone knob – made between and – so definately not 60s, though the serial numbers were everywhere at this time, so this bass is effectively undatable. Don’t ask Gibson; the person that they employ to answer such questions knows none of the caveats and exceptions about dating your instrument.
You might as well ask your mother. The pots are interesting. My SB also has ’66 pots, but with a very odd manufacture code BD No idea who made these, however the part numbers also on the pot are BA – which was certainly used on the Kalamazoo KG guitars and – , which I don’t recall seeing before. Note, they do not seem to have been used on the Kalamazoo basses with the EB humbucker , at least on all the models I have examined.
What part numbers are on yours? Note, all of these instruments use the same single coil pickups. As Dave said your pots are indeed centralab ’66s, and it is my opinion that these pots are leftovers from the Kalamazoo range of guitars, which were made en masse between and They actually made of them in those 4 years in comparrison, Gibson only sold EB0s in the 20 years between and Were they particularly suited to single coil pickups?
The fact that they don’t seem to have been used on the KB bass, sort of implies this, though perhaps they are out there I would not be surprised to see these pots on melody maker guitars from around that time too, as they too were low-end models with single coils, and scratchplate mounted controls.

Pot codes and source codes information below: These codes often overlap within a few months to as much as a few years when used to determine the originality of a particular vintage guitar or amp. The best way to date your vintage guitar or amp is from the manufacturers serial number and then use this guide as a reference to date the parts that make up said guitar or amp.

NC , NC X photo above: Note the relocated pilot lamp and the hole plugs covering the unused crystal filter control holes when compared to the NC X header photo. History of the Design and Production – Many radio engineers of the thirties believed that the absolute, best sensitivity and stability of a communication receiver’s RF amplifier, First Detector and Local Oscillator could only be achieved by using “plug-in” coils.
This type of approach eliminated problems of lead length, shielding and stability along with isolation of unused tuned circuits – problems that were commonly found in broadcast receivers using conventional rotary bandswitches. Plug-in coils were a hassle, no doubt. James Millen, National Co. But, how to effectively eliminate the valid arguments against plug-in coil use in a new product? Certainly, National was having fabulous success with the HRO receiver, which had been in production since early It was well-known that the HRO’s legendary performance was in-part due to its plug-in coil sets.
The chassis of the NC The NC Features – National’s mechanical engineers offered a solution that solved most of the negatives of plug-in coils and retained most of the advantages. With the use of a movable cast aluminum coil box called a “catacomb,” all of the coils would be mounted in individual shielded compartments with short contact pins mounted in molded insulators on top of the catacomb. A large band selector knob on the front panel of the receiver would turn a rack and pinion gear mechanism that would move the coil catacomb into place, thus engaging the proper coil set pins into short, fixed position, spring-contacts mounted under the tuning condenser in insulator blocks.
The mechanical action simulated plugging in a three coil set for each band with the ease of turning a knob while keeping all of the unused coils isolated and shielded. The split-contacts were not soldered together but rather had the screen voltage wires connected to each of the two halves of the contact and when the coil pin, which wasn’t connected to anything inside the coil catacomb, engaged in the two halves the circuit is completed and the screen voltage was then routed to the RF and IF amplifiers.

Seattle, Washington, Ships to: Finished in original Cherry nitro lacquer with nickel hardware and hailing from what is arguably the most celebrated production year for any SG model, this guitar is utterly unique and as Vintage Guitar Magazine succinctly puts it, “the number of non-white SG Customs that have surfaced over the past 50 years could be counted on the fingers of one hand.
The guitar is dynamic and soulful, and when you strike a chord the entire instrument responds with a lively spank and rumble. As per spec for early ’63, the pickups consist of three original hand-wound humbuckers, one still retaining the PAF sticker, while the other two have early patent number stickers on the baseplates. With the stock wiring on the three-way pickup selector toggle in many ways not complimentary to the wide tonal palette of the instrument, this SG has been cleanly rewired so that the bridge and middle humbuckers are engaged when the switch is down, all three are activated when the switch is in the middle, and the neck pickup is singled out when the switch is in the up position.
The results are astounding, with incredible bark and sweet, glassy articulation in the down position, contrasting with a thick, throaty howl when all the humbuckers are engaged. Of course the neck pickup on its own is a singularly stunning sound, with a warmth and roundness that stays focused and clear.

Congrats on a really nice looking console. Static crashes have been so bad here I have had problems hearing you guys. I bought “used” mixer components off of eBay and cobbled them together. The main mixer guts came from a Shure Prologue mike mixer, the equalization came from a Samson Mixpad 6 mixer, the cue amp I built from a kit, the phantom voltage came from a junker Nady power supply. The pots with cue switch, switches, red lamp, tie strips, relays all came from Allelectronics.
The wire including shielded cable came from the gutted old LPB boards as well as the knobs.
