Testing Leach Low TIM

I hate to beat a dead horse ... but this will make you laugh.

MCM finally sent me a note saying that it is normally not in their procedure but they would replace the transistors (ON Semi 2N5416). I felt grateful (let me lick you're azz, MCM). No explanation about the sex change though.

The transistors arrived and I finally got around to testing them ... SAME RESULT. NPN. B-C LOW RES, B-E LOW RES, C-B OPEN.

Maybe I'm loosing my mind, maybe I never had one.

If anyone wants to check these out send me your address.
 
You need to speak with someone on the phone. Too easy for them to shrug off an email with an attitude of 'I don't give a crap what his problem is'.

Edit: What? I'm astounded! 'Rap' with a 'C' in front is censored? Thought we'd all been out of kindergarden for a while...:rolleyes:
 
Your right EW, I probably won't get anywhere with them on email.

I had great luck with ON Semi, they sent me 10 MJ's for the Leach amp for only postage cost. I simply explained what I was using them for.

Allied has a good stock of transistors (at least what I have been interested in) and prices are good.

Digikey is hit and miss and there prices are too high.
 
I CALLED MCM AND DISCUSSED THIS LITTLE THING WITH ONE OF THEIR TECHS. HE COULD NOT IMAGINE THAT A PROBLEM EXISTED SO I ASKED ON AND THIS WAS THEIR RESPONSE -

Thank you for contacting ON Semiconductor

The 2N5416 device is cancelled since Septemver 1999 and we do not
manufacture it any longer.

Subject: Transistor Problem

Description of customer request:

I have been in discussion with MCM, an online supplier of electronic
equipment, about a transistor type, 2N5416 (PNP), they supplied to me in
September 2006. The label on the collector is ON.

The particular units I received tested NPN. I notified MCM of this
problem and they sent replacements which also tested NPN.

I was since told that ON no longer manufactures 2N5416.

Is this true?

PASSED THIS ON TO MCM AND THIS WAS THEIR RESPONSE -

I checked 6 2N5416 from stock and confirmed they test as NPN. Pulling stock.
We apologize for any inconvenience.
