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.

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.

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.

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.

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.
