Transistor alternatives

[markbee]

Hi there.
Im collecting parts for my newest build. Death by Audio Super sonic fuzz gun. Im building it according to this vero layout http://tagboardeffects.blogspot.com/2012/04/death-by-audio-supersonic-fuzz-gun.html .
But local electronic stores(ges.cz; gme.cz) do not offer any of those transistors. 2N5089 and 2N5306.
Is here anyone who knows the best alternatives to those to? But something more available. Thank you

you can purchase those easily online...

but you shouldn't have any problem using any common modern npn silicon with hfe 300+ for the 5089 and any modern npn darlington for the 5306

All the 5089's I have are fairly high gain, most about 600-700 range. I was just measuring a ton of transistors the other night, trying to find a matched P-N pair in high gain and lower gain. 2n2222's are around 250-300, 3904's and 4401's all measured around 350. My 2SC1815Y and A1015Y's all hit around 200-250.

2N5306 is Darlington with 7000-70000 DC gain, lol... DATASHEET

So, I'd say anything about 650-800 gain for the 2N5089's, and something like MPSA14 should work for Q3.

my 5089's are in the 400-500 range (sheet says 400+), so most likely do not need hfe 600+

those modern si fuzzes are rarely that picky, but who knows


edit: and remember you can make your own darlington
