You mean terminal strips?

Radio Daze has them I think.

Recently (within the last year) I was able to stock up on terminal strips at Radio Shack. Might still be possible, but you will have to locate them on your own. The kid behind the counter will only be able to give you a blank stare if you ask. I bought a nice assortment of alignment tools from RadioDaze a few years ago. I think they still have them. If not, AES does.

They may have the alignment tools, also. If not, MCM is one among many that will.

That stuff is called "tag strip" here in the UK. RS (Radio Spares) sell it

A bus bar is usually (but not always) a strip of conductor that carries power. I worked in a place that made huge industrial 3 phase electrical distribution boards. Large steel panels full of meters and switchgear etc - fuses too. Some of the the bus bars in these things was made of solid copper bar, 1 1/4" thick, some 4" high, and upto several yards in length. Some were even thicker than that!

http://en.wikipedia.org/wiki/Busbar

They wrote it as "bus bar" and pronounced it "buzz bar", I've always pronounced it "bus" as in "Columbus" - ho hum.....

Some designs used a thich piece of bstr wire (like 12 or 14 guage) that would run suspended from the chassis and be connected thereto at only one point, usually at the same point as the first filter capacitor and center winding of the power transformer, else at the first B- point depending on the circuit. You can just take a piece of romex about 1 foot long, strip it, and you will have enough for just about any job. You can strip off the insulation and use it for insulation when wiring up new parts.

An even better way is star grounding, which there is lots of information on the net. Star grounding works very well for high gain audio amplifiers for microphones and magnetic phono cartridges.

UK has RS as well. Radio Shack over here on the mainland
ground bus has many applications. common ground is another name. that is to eliminate ground potential. the difference measured in ohms of one ground to another. introduces noise either in audio circuits computer systems telephone systems telemetry systems. you dont want two grounds :shock:

Unless you know otherwise, RS and Radio Shack are two totally different companies. Here, Radio Shack was once called "Tandy". They didn't really sell many components since most of the semiconductors they sold were American part numbers. Here in the UK we didn't at the time use many 2N type devices, using the BC, BF, AF, OC (etc) prefix devices instead. That is changing now thankfully. Also, Tandy was expensive to the point of stupidity, but their Realistic branded stuff was generally decent. I have one of Radio Shack's digital meters bought from Tandy, had it years and its still working well! Cat no. 22-7220

RS has been around for decades... http://www.rs-components.com/index.html

Allied of course. have heard of that one. Radio Shack is not well respected for price. they kept that name not having much to do with amateur electronics any longer. Ham and radio shack are synonymous with radiomen of course. I do remember Tandy. they used to advertise it that way
'Radio Shack a Tandy company'
