I used Jansen Caps from Parts Connection (plus a coupling cap) and wired them in parallel. they do not fit on the board so I just hot glued them in place on the underside of the connection box (where red, yellow and black hook up)
They sound good so far letting them burn in for hours before I do any critical listening.
I also just added coupling caps to my FM 155 so I also did too many upgrades at the same time.
I am interested in the torroidal and I will do the resister mod asap
