Suggestions for B135?

[rousejeremy]

I have four B135 transistors and no idea where to use them. Any suggestions?

I can't find anything on a B135, do you mean BD135? If you do they're low gain NPN transistors, so you could try a fuzzface or something like an NPN Rangemaster booster type circuit.

  You can find out if it is a bipolar transistor, and whether it is NPN or PNP.
  Stick the leads into the DMM's Hfe meter, every which way.
  One way [lead orientation] should produce an Hfe number in the 'ballpark'..I dunno, somewhere between 50hfe and 800hfe is probably a gain reading which you can use to write down the pinout of the transistor.
  Then you can measure the B/e diode to see if it falls in the Ge or Si range.
  For Jfets and Mosfets it's a different story...

I should have been more precise. I have four of these transistors, most marked differently
1. 2SB135
2/3. B135 x2
3. B135E

Anyone know about these?

  2SBxxx is Ge..pretty sure...
  We'll know more after you test them.
  Others might be too if they look similar. 
  they might be good candidates for Fuzz-Boosters, that depends on how well they do in Fuzz or boost circuits, the tale can be told also by measuring and calculating the leakage and Hfe gain, see GEO, and GEO; technology of the Fuzz Face

I measured the HFE with a DMM.
2SB135=175
B135=270
B135E=217
B135=268

They only registered on the PNP side of the meter. Do these numbers seem high? What does it mean?
I'll check the leakage once I understand what it's about.
I was hoping to use these to make a....let's call it a Fact Fuzztory.
