Can't seem to find a place that sells them anywhere. Is anyone aware of alternatives?
I live in Canada if that makes a difference

Anyone know where to find some 2N5952?

Thank you, quite expensive probably will look a little more but it is better than nothing.How about this?

It is a bit expensive but it is a quad matched set of transistors. Those are always a bit spendy.

Could you elaborate? I buy transistors on Tayda for 30 cents, what's the difference here?

Yep. In some circuits the transistors have to be matched in order for the circuit to work properly. I don't know a ton about transistors in modulation circuits, so maybe somebody more experienced than me could elaborate a little more. So that costs more. It's also a quad matched set, so all 4 of then have to be matched. It can take a lot of transistors to sort 4 matched transistors. Also, if you say you can't find any, then they are probably a rarer component that demands more money. Supply and demand, rarity and a decent amount of that specific transistor (think 100 at the minimum or more) to be able to offer a quad matched set. That sums it up nicely.

It depends on what you want them for
If it's a phaser buying a matched set to me is the easiest solution
Trying to match them yourself can be hit and miss and you'd need to buy a few then test and match them as already said, add to that the fact they're now obsolete you'd also run the risk of buying fakes
You can use different FETs but most through hole FETs are hard to get these days so people generally use SMD FETs and adaptor pcbs
Our resident match king @fig will let you know how long it takes
A set if that's what you need at that price is ok when you consider a guaranteed genuine 5952 can cost up to $5 for one and FETs as we know can be all over the place even from the same batch

First off, 2N5952s are obsolete, so they’re gonna be more expensive to begin with— you can usually expect to pay ~$1-2 each for many of the obsolete JFETs, and some of them as high as the $5-10 range. With many effects you need to match the gain range of the transistors for optimal performance— this is especially true in certain modulation effects.
Since you’re asking about 2N5952s, I’m guessing you’re building a phase 90/XC Phase. That will need a matched quad pair in order to function optimally. Your options in that case are either to buy a matched pair for $15-20, or to buy 50+ un-matched 2N5952s, measure each one, and hopefully you’ll be able to assemble a few matched sets (you’ll almost definitely get at least 2 matched quad sets that way, but the fewer you buy, the chance of a matched quad pair appearing decreases exponentially)— it’s a much bigger upfront investment, and it eats up a lot of time to go through and test them all, but you’ll hopefully get a few quads, and you’ll also have plenty of matching pairs and singles to use in other projects. The cost of the expensive quad sets is because someone else is takin the time and doing the labor to test and match all of the transistors. It’s just up to you how much your own time is worth, how much use you’ll get out of all of the other transistors you’d need to buy to assemble your own quad set, and what you’re willing to put out as a maximum upfront cost. Then you can decide which is the more worthwhile method to you. Hope that helps!

Out of curiosity, what does it mean to have matched pair? If I were to buy a bunch and match them myself (I am not), how would I go about doing that?
If you can't tell yet, I'm quite knew to all of this.

I am building a phaser. The idea is to learn more and learn to build my own. I always find it funny that I started getting into pedal building thinking I would save a lot of money

If you really want to save money building pedals, try the bigger stuff from DeadendFX— instead of buying an original EMS Synthi HiFli unit for $6,000, you can build your own for only $550 and 200 hours of labor
