MMBF5457’s and where they at?

I've enjoyed the SMD stuff so far.
They'll never take my breadboard!
SMD components are cheaper, and take up less space.
I have enough thru-hole to last me! I just need to rent that mini warehouse for my passives.
DSP is good, just different.
I just bought a $3K tube amp!
You can still build analog circuits with SMD.
There goes the badass clipping options.
Ooh! Which amp?

Fender '64 CDR. 20 watts of tubular bliss. I'm not saying it's the last amp I will buy, but it's certainly the only one I really need covet.
Very cool, congratulations! I’d love an old fender. After 30 years of playing solid state amps I finally purchased my first big boy amp (Orange TH30 with an Orange PPC212c) about a year or so ago. I was blown away by the tonal difference. Unfortunately, I’ve yet to turn it up past about 2 (if it went to 10) because of how incredibly loud it is -I’ve never turned it off the 7.5w setting. However, I’ve got a Fryette PS-2 on the way that I hope will help in that dept.

That's a sweet attenuator!
That’s what I hear. When I couldn’t find one on the used market I figured that was a good sign. Never owned one before -never needed one with solid state amps. I’ve been told it’s important that I hook it all up correctly :)

I fully appreciate your insight, as we all have different reasons for why we love this hobby and everyone's journey is different. I like the old school. Always have, always will. It's a dying art form, I like that I can work on Amps and pedal like they did years ago. I think thru hole looks awesome. I don't need everything in a 125b. I also feel like you that there is something relaxing and fun about populating boards. I don't mind smd jfets or transistors and even some ICs. But a whole board? Not for me. I don't want a hot air station, I like the technique of soldering thru hole with an iron. I don't like digital because the future of digital is algorithms. I don't want to program 1s and 0s. I'm all about learning as well but I want to keep that analog aspect, like analog circuit with digital switching or tap tempo. But all digital?.I want loud, heavy tube amps pummeled with fuzz at house shattering levels cause at the heart of it to me, that's what rock n' roll and playing guitar is all about.
[heavy sigh] yep. exactly my thoughts unless I go out of my way to argue against it like in that post, and even then this side usually wins out

In all fairness I get why more and more companies use smd. It's faster and easier to get product out the door. Probably cheaper in the long run too. If I planned on selling larger quantities or starting a business I would totally go smd.

After reflecting on my distaste for digital effects that are programmed, I think it has to do with the fact that most of these effects change the fundamental sound of the guitar. I want my guitar to sound like a guitar, but sometimes with delay or tremolo and phaser. Many of the digital effects are more the instrument and the guitar is a mechanism to operate them. I get how some people are into ambient playing. I see myself as someone who plays guitar and not pedals. If that makes any sense 😂

That makes total sense, I mean I rattled off all of those reasons but I really only use fuzz pedals lmao

Dang. I only bought 10 of them because I thought they’d be around for a while since they’ve been in stock there for a full two or three years I believe. Should have gone for 50 or more.

Are those 2n5457s from GuitarPCB working out for you?

I recently bought a batch of 10 (at $1.69 each) and my tester shows them as BJTs, not J-FETS. His site says, "Guaranteed Genuine" and "from my own personal collection." But I ordered in Dec. 2021 and I'm concerned his personal collection ran dry and he re-stocked with some re-badged BJTs.

Have you reached out to Barry? I picked up 25 from him about 2 weeks ago. They read as FETs and the Idss readings were in spec, but the Vgs(off) readings were low on all samples. I imagine everyone's stash of popular THDs are thinning.

I did actually, just before I posted. :) Because I didn't want to seem like I was smack talking without first reaching out to him. I've been meaning to write him, just forgetful.

Just to check that my cheap transistor tester wasn't misreporting, I snipped an ancient 2n5457 from a scrapyard project and it read as a JFET. Then I tested some Aion SMT 5457s and they also read as JFET. 🤔

I didn't even ask him for a refund cuz I know it's hard to run a small business and I'm sure these will be useful for something. But I'm reluctant to use them as 2n5457s. I just wanted him to know in case he got a bum batch.

On a positive note, the quad-matched 2N5952s I got from Barry tested right and were perfectly matched.

Haven’t tested them yet. I ordered in December too I think, and since then my work bench has been blocked by boxes while my parents get some renovations done. It’ll suck if they’re bunk

Hey, no need to worry. Barry wrote me back and assured me that he tests everything before he ships. And he sent me a screenshot of his Atlas DCA55 testing one. I'll just copy-and-paste his message in here since it demonstrates the pinnacle of customer service so I don't think he'd mind.

Hi Matthew,

My batch of 2N5457s that I have been selling for the last 3 months are absolutely legit and work as intended in a circuit. Also if they were not I would have received hundreds of emails. You are the only one.

I use an Atlas DCA55 to test all batches before shipping and as you can see in the photo I have attached they are N-channel JFETS. If you are using one of those testers from China like they sell on eBay they do not always work correctly. I have verified that myself.

The alternative best way to test if a transistor is a JFET if you do not have an Atlas is to try it in a circuit like one of my Stage 3 Boosters like and make sure it works like it is supposed to. These JFETs work fine. Like I said if they did not I would have tons of emails and forum issues as I have sold nearly 4,000 of these in the last 3 months.

Now I do appreciate your email for the reason of also warning me if I had happened onto a bad batch without realizing it and for that I thank you. If you like I will individually hand test another batch of ten on the Peak Atlas as shown above and mail them to you FREE of charge. You can then use your tester to see how they read on it knowing that I have already approved each and every one with an industry-standard unit.

My policy is always to refund though if you are not happy and I will do so but I would appreciate if you send them back to me even if it is a first-class envelope with a stamp.

Let me know,
Barry

His hunch was right; I'm using a $16 no-name transistor tester from aliexpress.com, so I definitely trust his Atlas more than my reject genero job.

In my defense, I'm not psycho, just very wary of counterfeits. The "F" logo on these is pencil thin. When I compare that to other Fairchild transistors in my stash, they use a thicker boldface
F logo. There also seemed to be tiny micro-abrasions on the surface which made me worried they had been sanded and re-badged.

I have a Peak Atlas tester and a T7 tester, I find they're both useful, but the T7 often gives screwy results for transistors. For Caps, resis, LEDs etc, the T7 is excellent.
