Stuff you wanted to know but were afraid to ask

Why do reverb tanks use RCA jacks? Only thing I could figure is because these connectors are much shorter, and a regular TS jack would stick out all silly or sideways .Shielded TS would function all he same as shielded RCA...?

Without doing any research, I saw Matt Berry talking on That Pedal Show about how there are consumer reverb units that were intended for people to add their own reverb to music. So I'm taking a wild guess that it might be because they come originally from consumer audio where RCA cables were the standard, and it's mostly convention?

My understanding is also that the advantage of TRS is that the jacks can take a lot of unplugging and plugging easily, while for something like reverb tanks you don't need to unplug them that often.

So all signal diodes are pulse diodes?

I think it's the other way around, but that's maybe not entirely accurate.

Switching and signal integrity (e.g., rise/fall, wave shape) are important features for both, but they deal with different types of signal information. Pulse diodes have higher peak voltage/current rating--which differentiates them from many signal diodes--and are extremely fast. Think CD reader vs CMOS logic and transistor switches. Both are used to convey logic states, but the application is different.

These are both in contrast with rectifiers, which are really just focused on the cruder voltage blocking or rectification.

For our applications here, these differences don't matter much.
 
Ok here's a dumb one: what is the difference between this pot and this one?? I have a few of both Tayda sku# and cannot for the life of me figure out what the difference is, if any. They look the same other than one having DB3 printed on the side and one having EC4.

I don’t think I’ve ever seen an item removed from tayda. It just becomes permanently out if stock. The difference probably is some attribute that is not visible on the customer side.

They regularly have multiple skus of the same item. It baffled me for a long time.and then I just accepted that life is like that. 😁

Pin heanders are great and cheap. Much more resilient and conveniently spaced.
I've started bending long headers for footswitch boards when the PCB is too small to just place the pads on the 3pdt board above the PCB(and use headers).
If structural integrity is needed, 100% headers.
Otherwise, save the 15 cents if you must. But headers are nice and easy and one of the cheapest components you can buy.
They.can also make testing a little easier.

What got me thinking about it was the set of mc33178 that showed up today.

This is going to sound crazy, but sometimes you don't even have to use either.

If the breakout board fits you can lay it flush against the PCB and let solder flow through the pads, no headers required... I'm not recommending you do it, but I've seen it done a time or two.
