Banana plugs into Pass x.5 amps

Hello All,

The .5 series of Pass Labs amps do not accept banana plugs due to the plastic inserts Pass has placed into the binding posts to meet some legal requirement (in Europe if my info is correct).  But I learned today that these inserts may be removed by backing out the post nut all the way to reveal a very tiny brass pin that passes thru the insert stem.  Pushing out this pin (in the proper direction if it is tapered) then allows removal of the plug and insertion of a banana plug.  I checked one of my binding posts today, and sure enough, there is a little brass pin.

But before I proceed with this magnifier-aided surgery, I have two questions for anyone that may have already done this.

Is the pin really tapered requiring directional removal?

Once the plastic plug is removed, will a banana securely fit into the binding post (they seem a bit short in length)?

Hopefully someone will respond shortly.  If not, then I'll give it a shot tomorrow and let someone know what I discovered.  Just didn't want to maybe permanently booger-up the post's "factory look" if unable to get that micro pin back in.

Thanks.  John
