Quick question what kind of transistor NPC 3565?

[endorphin]

Could someone tell me about this transistor. Silicon or Germanium? What could they be replace with. They belong to a Nameloc pedal.

[theehman]

Silicon NPN.  Should be the same as the 2N3565.

OK thank you!!!!!!  They definitely sounded like it. they belong to a 70's Fuzz/Octave Wa Volume  and i wanted to put in a switch and some sockets or something to change between the stock silicon and germanium if it is possible. I lack knowledge about transistors so would anyone know a fine replacement of germanium ones to get that some 60's fuzz tone. And a link to a reverse polarity protection to add on to it to hook it up to an adaptor.

I may be able to save you some trouble, based on your comments.

...i wanted to put in a switch and some sockets or something to change between the stock silicon and germanium if it is possible.

It is possible; however, if you get germanium PNPs, you must also change the polarity of all other polarized parts in the circuit, as well as the power supply. However it is very impractical, and unless you get NPN germaniums, it will be prohibitively expensive just for the sheer number of switches.

I lack knowledge about transistors so would anyone know a fine replacement of germanium ones to get that some 60's fuzz tone.

One important bit of transistor knowledge is that simply replacing (or adding, or rubbing on  ) silicon based circuits with germanium most assuredly does not give any specific fuzz tone. It's very much not that simple. Even if you make the changes needed to reverse polarity, or use rare and expensive NPN germanium devices, the germanium devices may well not produce any sound at all, because of their very different nature.

Thank you I appreciate the information yeah that wouldnt seem too practical maybe ill mess with it in the future as for now im doing my research.

If you can get any OC140, OC141, or OC139 transistors they are usually extremely low leakage and you may be able to sub them directly for silicons if you want to try.
