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 following letter and interview was sent to me by Doug Noble, a noted journalist for the U. Note the surprising admission by Jeff of just who is the loudest drummer he’s ever played with! Also what Jeff really thinks of Jackson Soloist guitars! For some more of Doug’s Jeff Beck interviews check out his website! The interview consists of all the material I didn’t use in “The Guitar Magazine” – obviously, for reasons of copyright and etiquette none of “The Guitar Magazine” material could be reproduced.
The electronic is alloriginal and untouched with two Centralab pots stamped dating them to 12th week of , the original pickup has an output of 10,86K, the neckstamp reads 5 APR 65 C. The neck is a medium-sized C-profile and very comfortable to play.
E-H talking pedal I just earlier this evening found out that what I thought was a talking pedal was actually called a Golden Throat. What does a talking pedal do, and how does it work? Is it the same thing as a Golden Throat? They are completely different. The golden throat is a “talk box” like Frampton, Walsh, etc used. It is a speaker driver connected to a tube which goes in your mouth and needs to be miked through a PA to be used.
Your mouth acts as a filter. The Talking pedal is like a big wah wah pedal, but instead of saying “WAH” it says “eee aaaa iiii oooo uuuu” when it is moved, the vowel sounds. It goes in the path between the guitar and amp, much more useable than a talk box. But the talk box can make more different sounds. In the Bad Stone I can’t switch back and forth from auto to manual.
Wah Wah Mods The mods on this page are primarily concerned with the Dunlop Crybaby and Vox V wahs, but they can be applied to most wahs which have an inductor. Mods to PCB These mods are all fairly cheap to do and they’re reversible, so it’s not the end of the world if you don’t like the results. Refer to the photos below if you’re not sure which parts to change. This gives a more vocal quality to the wah.
Pots You can use any old pot, but cheap carbon pots will wear out in no time and standard log/lin resistance tapers aren’t ideal for use in a wah. Commercial wah pots have a kink in the taper, where the resistance suddenly shoots up within a small degree of rotation.
Return to the Main Index. Sometimes there just isn’t enough information on electric instruments and amps to allow them to be properely dated. And many people ask me to try and determine the year of their old amplifier, or to help them with the year of their older off-brand electric guitar. Since I primarily collect amps by Fender, and guitars by Gibson, Fender, Martin, National, Epiphone, Gretsch and Rickenbacker, I really can’t help them with these other less popular brands.
As you have probably noticed, there is plenty of information here to help date the brands that I am interested in. But where does that leave everyone else? Well I’m not one to leave you out in the informational cold, so here’s something that I use quite often in dating amplifiers and electric guitars. It’s called the “source-date code”, and it can help determine the approximate age of an electric instrument by the date its components were manufactured.
Source-Date Codes On American made vintage gear, the pots and speakers provide an excellent opportunity to date a piece of equipment by referencing their “source-date code”. The source-date code found on pots and speakers gives the manufacturer and date roughly when the components were made. It may have been some time before the part was installed at the factory, but it still provides a good approximation of when the gear was made.
The source-date code will signify the earliest possible date that the instrument or amp could have been made.
Commonly Seen EIA Codes
This list is circa , and some codes have been reassigned or added since that time. 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: One alternate scheme is:

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.

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.

How the “Hand Stamped” Date Code Works. The Code on the tube chart of your Fender Amp is made up of two letters. The First letter equates to the Year and the Second letter to the Month.
A true holy grail instrument in every sense, this SG combines the inherent warmth and power of a solid mahogany body with the attack and articulation of an ebony fretboard for an ideal tonal pairing. The guitar is dynamic and soulful, and when you strike a chord the entire instrument responds with a lively spank and rumble. 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.
The guitar weighs in at 7lbs 14oz and balances well on a strap. Currently setup with strings, the guitar is dialed in for optimal action and intonation. The neck has a c. Lassic slender C profile that increases modestly in depth and shoulder as you move up the board.

Mar 05, · As far as dating the amp the only thing I can use is the volume and tone pots. 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.
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. The VU meters came from eBay. I maintained XLR connecterization between components using 1 foot jumpers off of eBay. All screws, standoffs, etc came from the old mixer hardware. The original board was toast.
