This listing is for a job lot of vintage germanium transistors, all taken from new old stock, and then the duds removed and binned, just leaving the ones suitable for fuzz pedals.
Each transistor has been:
-
Individually bagged and numbered
-
Tested with a TC1 semiconductor tester
-
Recorded for polarity, hFE (gain), and leakage (ICE0 / ICES where available)
A spreadsheet of results is included so the buyer can see exactly what is being purchased.
Included types:
-
AF124 ×1
-
AC127 ×6
-
AF139 ×2
-
AF116 ×1
These are genuine germanium parts of interest to guitar pedal builders, audio experimenters, and vintage radio restorers. Some test as good candidates for fuzz pedal circuits (low leakage, suitable gain); others are noted as higher leakage or marginal in the spreadsheet.
Please note: test results on germanium transistors can vary with ambient temperature and the type of tester used, and often vary between tests, so treat them as a general guide.
Only the transistors listed above are included in this lot.
Notes
-
Sold as tested and described.
-
Supplied in numbered bags with the test data.
