A Better Binding Post For Point To Point

You all have probably heard of my amp, emulating tube sound but with transi stors right ?

Well some part of it will be PC board but some parts will be point to point , especially the power amp part, output section.

What I want is a better binding post, not like what you used to see in old radios, where the wire is wrapped around, I don't want that. What I REALLY want is the terminal strips like Tektronix used to use.

I am sure those are unobtanium, but there has to be a better alternative th an those regular ones used in every $29 radio from the 1930s.

I really do like those old Tek ones but I am not willing to scrap old Tek s copes to get them. Goes against my religion. I have never seen a Tek that d eserved to be scrapped like that. Some of the 7000 series ones get some rea lly bad problems, like attentuator or timebase switches falling apart but t hose didn't use the strips I am talking about.

In some cases I see that those strips would be better than a PC board. It i s easy to keep all the parts on the same plane, eliminating some inductance or whatever and making other factors a bit more predictable.

What's more I want something that looks cool. Personally I couldn't care le ss (I tried) but for the customers who run from the esoteric lovers to the really weird, they would appreciate it and with what I am asking for these things they should be pleased, not see what looks like the innards of an "A irtone" kitchen AM radio. What's more I think they would be easier to use.

If I have to use the regular ones I will, but no way am I wrapping the wore around before soldering it. In fact some old timers might remember when "t hey" recommended not wrapping the wire around anymore, just get it through and make a little hook at the end. That way when a component needs to be re placed it is not a major PITA. And try to keep it all level.

The circuit is not so complex it would need a multilayer board, it is built on a couple of resistive dividers going to the outputs.

Anyway, it is getting to be time to figure out the layout of the thing and what I can get determines certain things about that.

What can I get ?

Whle Tek was doing the ceramic terminal strips, HP was using rows of swage terminals on phenolic boards. You can still but turret-style swage terminals. Maybe you can install them on some really cool looking substrate, amber lexan or corian or some polyamide laminate.

Backlight that with colored LEDs and make those audio types swoon.

Keystone makes this:

Or do it on a PC board, like the lower image here.

There are reasons and most of them have to do with marketing. They also hav e to do with long term longevity, a hole could burn on a circuit board, so what has to so with power is not. Other parts, preamp, tone, whatever other things I decide someday, that is different. Dealing with line levels and c urrent limited power cool, PC boards are fine. But where there are many man y amperes, no. And that is one of the selling points.

With something like this, that expensive, I pursue indestructablity. I know it can never be attained but the closer the better.

You should see some of the shit they get big bucks for. (well maybe you hav e, it is almost .... nevermind)

I suppose I wouldn't mind an e.g. guitar power amp with an output power stage that burst into flames at the end of the widdly-widdly guitar solo, very impressive, u get all the females that way. Then only $3 to repair it and back out again tomorrow night!

there's a certain logic to that I guess

Several solutions: you could get some printed circuit boards made (long skinny ones) with plated-through holes, and reinforce the holes with soldered-in eyelets (rivets). Leads can be thrrust through the rivet hole, and soldered there, for easy remove/replace later.

There are also turret-like rivets that can be swaged into a snug hole, or press-fit into printed circuit plated-through holes

And for direct chassis mount, there are standoffs that bolt down on one end, and accept solder on the other (but these are rather pricey)

You can also make PCBs that imitate turret boards etc. Avoiding board burn is simple: don't run the parts too hot. Spread your P_diss out if you can't reduce it.

There is a madness to my method. I mean what you know.
