AC Datasheet, Equivalent, Cross Reference Search. Transistor Catalog

It’s unlikely, but not impossible. I think datasyeet is 5uA into the base, which is uA or so emitter current for a gain of Incorrect use of model parameters Simulation canceled.

If their account is deleted they probably had shitty feedback and just ac1288 a new one. That’s what I thought but I wanted to be sure.

The present state of the electronics art permits many of the transistor parameters. Ifstate of the electronics art permits many of the transistor parameters to be designed for various types. If you find low gain on all your MP40s, it could be that you’re testing under different conditions than the datasheet specifies.

Strides Towards Quantum Computing: Sellers that have stock are very likely to conceal their sources at all costs.

Submit a new text post. Fuzz simulation – Ge Transistor. In the Model Maker dialog, I modified the parameters as daasheet. You gave me some good topics to google and learn about. Hook up a voltage and a couple resistors and see if they meet the datasheet spec? Parameter ‘VJC’ must be greater than zero doAnalyses: Aug 9, 8. They’re made in China.


Try some 2N transistors from Radio Shack. Does anyone acc128 the likelihood of getting a bad one if it’s untested or what value is sensible for the transietor, or the effect of different hfe values with regard to a Fuzz effect pedal? Maybe, if you live near a mainframe junkyard. Discussion in ‘ General Electronics Chat ‘ started by stoopkidAug 8, If you buy lots, you’ll start to notice that they have holes in the gain ranges usually around the middle of the speced range from when they were picked over for ttransistor original uses.

Now it could be that Russian manufacturing just sucked or that they’ve been picked over for the good ones. Accelerometer Demo running on 8-bit S08 AC in data averaging mode. Message 9 of Transstor 20, 10, 1, Aug 8, 3. I tend to think it’s from the fuzz face circuit current, but then it would seem like the second transistor gets more current than the datasehet, yet the testing circuits out there use the same current regardless of what transistor you’re testing, so are the measured numbers from those circuits really applicable to the ranges we’re looking at for a fuzz face?

I’m no good at guitar but that should give an idea of what it sounds like. Want to add to the discussion? Mar 3, 1.

AC NTE Equivalent NTE TRANSISTOR PNP GERMAN – Wholesale Electronics

Are such still available? RCA H Abstract: Figuring out how much current a meter uses to test a transistor isn’t great fun though. You test for both gain and leakage.

In my entire career I made circuits with extremely low distortion, not this noise. Message 10 of This is an open community for the do-it-yourself pedal builders of reddit! There are links in the sidebar, but i’ve read all them and they don’t tell you how to find Ge transistors in bulk. Germanium transistors have been out of production and valuable to pedal builders for a long long time. Try to see if it’s in the manual. I sold it a long time ago and never finished the second one so this video is all I have at the moment.


I’ve bought them in bulk off of ebay from a seller in Bulgaria i think twice, ’cause they were cheap lots and it wasn’t much to lose in case it wasn’t what i needed. Submit a new link.

Aug 9, 7. Message 5 of The very old AC germanium transistor had a different base-emitter voltage requirement compared to a silicon transistor and had a poor high frequency response so it will sound different to a silicon transistor.

My GTV transistors read vastly different though, which isn’t surprising given that the spec hFE of is at 10mA emitter current whereas the geofex circuit feeds about 20 times less than that. No file text available.


Your name or email address: I was looking for an equivilent to AC transistors. They vary according to the current that goes through them and temperature, of course. There isn’t really a trabsistor way to purchase GE transistors in bulk if you are a DIY enthusiast or small business. Message 2 of With a DMM using a different current?

The L on the pots means linear.
