If you want trannies just send me a PM. Price is $10/pair shipped in the US and $12/pair everywhere else.
A note on the matching. These have been matched to compensate for leakage, so if you have an Hfe slot in your DMM and you measure them they will most likely not be matched. To match germainium trannies you need to measure the total gain then subtract the leakage for actual gain. Germainium trannies are leaky and temprature sensitive so if you want more gain out of your fuzz you can just leave it out in the Sun for a couple minutes. This makes matching even harder because when you pick up a trannie the gain increases, needless to say it's not an exact science but I tried to test each one at room temp after giving a moment to cool after touching the leads and they were all matched within 1 Hfe.
The trannies I have are between 40 and 65 Hfe, spec on the 1304's is 40Hfe and speck on the 1306's is 60 Hfe, so not bad.
