Title: Help with parts ID on a veroboard project
Post by: bootlegnjack on March 17, 2017, 08:22:46 PM
Hi,

Brand new to this hobby and hoping to dive in with this veroboard project, Sunn Model T pre-amp.

(https://s22.postimg.org/uls9uzloh/Model_T_Preamp.png) (https://postimg.org/image/5sipuc2nx/)img host (https://postimage.org/)

I'm wondering what transistor to use for this?

If anyone can throw me a bone here it'd be much appreciated.  ;D

Bottom of the image says Q1-4: J201

J201 are FETs, not transistors, but those are what the transistor-y package stuff is on the vero.

It says near the bottom "Q1-Q4: J201" - so that's the transistors to use for all four of them.  'Q' means transistor for some reason. 

Just be wary of buying cheap J201 from eBay, they aren't always legit.

Edit: Yeah, What Alanp says.  He beat me by a minute. :)
