J&K has 2 options: New Marantz 8b OPT clones or send your core for rebuild. Be warned either options will be expensive. I ordered a 8b OPT clone for a buddy. It tested very close to the good trans on his 8b and can't tell the difference sonically. Replacing 8b the OPT is no easy matter. BTW if your friend decides to replace the OPT also replace the following: C16,C19, C20, C17, the HV rectifiers, the bias supply diode, C7A&B, C8A&B. Hope this helps.
