Title: output cap orientation in RuffonG's EA Trem...Please help!
Post by: sir_modulus on May 29, 2004, 10:52:22 AM
I couldn't find any .47uf caps for the output on the ea trem, and when i finally found one, it was electrolytic. Can someone tell me the orientation. One side goes to the fet(i think) other goes to output. This is the RUFF ON GROOVE EA trem. Thanks

OUt put cap?
 If it's the DC blocking output cap, the negative [on a negative ground circtuit] should go toward the outside, the + toward the circtuit.
 Whichever side of it's placement that measures closer to ground [lower positive voltage] should be connected to the caps - [minus sign].
 IIRC...
 Use a socket there, if you like...hard to beat them sockets for any parts that have a [?] that goes with them.

It's the cap that joins the circuit to the output(like the jack). the circuit has ground connected to GND on my PS. I have put a socket. If you could help me again that would be good.

Positive lead toward the MOSFET drain, negative toward lug 3 of the Volume pot.
