Poll - 13700 or 3080

[Scruffie]

This is just a general build question as i've seen it coming up quite a bit, in a case where an OTA was in a non-audio position (as some have complained of noise with them) and you only needed ONE would you rather use a 13700/13600 where at least half the chip is wasted (possibly more if you didn't use the darlingtons) OR use a 3080 to its full potential and save board space/pin soldering/whatever your reason.

And to up it, that space difference could be the difference in enclosure size of 1590BB to 1790NS (or 1590B to 125B if you prefer or 125B to 1590BB).

lm13700 and substitutes are generally much cheaper than the 3080. that's my reason. with the money for the 3080 i could buy a few lm13600, so i can have some left in the case something goes bad

CA3080, I think.

What about the BA6110 SIP? I've got a couple to play with, but haven't had the time to spend on it yet.

I bread boarded a PAIA Gator with both chips and didn't notice much of a difference in noise level. So I decided to design a PCB of this effect using the 3080 (like the original). I wanted it to fit in a 1590B and the 3080 takes up less space. I can still get these chips here in the UK and EU so availability is not a problem yet.

13700 cost about 20% of a 3080 last time I bought a 3080.

I did add the enclosure size part, the enclosure going up a size would mitigate those costs/savings.

I don't think those are still in production are they? The 13700 & 3080 both still are to some degree.

I haven't looked them much as they seemed a more obscure part.

And who voted bacon!?

I don't think there's a single answer to this. If space is a problem/consideration, the 3080 keeps things to 8 pins. The 13700/13600 is a much bigger chip.

For example, I chose the 3080 for the Engineer's Thumb PCB, even though the original Merlin designed called for a 13700.

However, in the Stone Cold Phaser, I'm running 3 LM13700s, and one of them is only utilizing half of the chip, but since I was already using a pair of 13700s, adding a third instead of switching to a 3080 made sense.

Bacon is ALWAYS an acceptable answer.

[GrindCustoms]

My vote go to 3080's, real estate is something that more than often becomes important to me. Never ran into any noise problem with them either.

I vote chocolate covered bacon.

And yet no kumquat love...

[timbo_93631]

I had to go for kumquats.  My cousin loves those little citrus devils.

In the UK getting 3080s for sensible money is still possible so that'd be my choice. However, thinking ahead, using something that's in production (this goes for all new effects) has to make more sense?

Then of course you gave us the option of bacon. When bacon is an option, it is the only option!

I'm declaring you an honorary American.  Chocolate covered bacon is amazing.
