Mullard T1 Germanium Transistors

Ultra low-leakage PNP germaniums - perfect for all your fuzzy desires.

These are T1 glass cased transistors, marked 'British Made, Mullard T1'. There's no other identification on them, so we can't say whether they're OC44 (most likely), OC71, or whatever. What we can say is they test really well and have sounded great in our test builds (RangeMaster, Fuzz Face).

Fully tested with a Peak Atlas DC75 and sorted for gain, compensating for leakage though it's very low on even the higher gain units (<100uA).

Available in different gain ranges. Don't be put off if any are showing out of stock. We'll be updating this listing as and when we get a chance to test more.

Pinout: CBE - Collector indicated by red dot.

Body - 15 x 5mm
