transistor ID? G'day all, I've just opened up an old VW car radio and found a few tin can type trannies. I was just wandering what they are and would they be usefull.The numbers are AS313, AS300, 2N408. Cheers Ken. |

I don't have any info at my finger tips but I'm sure you could use them. Measure the gains, the RF transistors might be a little low for some of the effects circuits. Measure Vbe, Vcb using the diode test on your multimeter, silicon's will be around 0.6V and germaniums < 0.4V (could vary). Also, when you use them, just keep an ear open for noise (hiss), if it's too high try another. I used to use those ASxxx transistors from old equipment when I was a boy. They looked like BC548/558 with an aluminium cap over them. If I find more I'll let you know, maybe someone else has the data handy. Regards Rob |

JoeGagan | Re: transistor ID/ ECG reference site According to the ECG cross reference thing at their website [http://www.ecgproducts.com/],that 2N408 crosses to an ECG 102A, A Ge PNP tranny. Time to build a Fuzz Face or Rangemaster! The other two part #s came up with no match at ECG. What year VW radio is it? I will be on the lookout. The NTE and ECG websites are great resources for Xreference info. I've learned a lot, and successfully substituted a lot of trannies using these sites.NTe is at: http://www.nteinc.com/ Good luck! |

JoeGagan | ECG Link and File That ECG link didn't come up right- it is: http://www.ecgproducts.com/ They also have a Zipfile downloadabe version of the entire crossreference chart [Big list]. Each ECG part contains a brief description of the part type and characteristics. It is set up like as one big long list, pretty easy to use. So you can have a Xref file without even going online. |

JoeGagan | NTE site not working for me For the last 12 hours, I can't get into the NTE site. [That's what prompted me to search for ECG] Anybody else having this problem? |

Re: transistor ID? Thanx all for your replies. I picked up the radio's at a flea market for $4. There were 10 Ge trans in the two, four of which have the right gain for the fuzzface and the Rangemaster. I rebuilt my RM with a Ge tran and what differance it makes from having a si in there. Cheers Ken. |

No kidding, I tried a 2N3906 Si in place of the 2SB172 Ge in the RM, and I really preferred the organic grind and more interesting character of the Ge. Brian May is supposedly using a Si version for many years now though. So , Ken what year is that VW radio? |
