You and everyone else. There ae no more replacements to be found and I would not suggest purchasing any used mosfets. The alternative is to replace with bi-polar transistors. Faster, more open and dynamic but the trade off is the musical mids of the mosfets. You use the bi-polar transistors but you need to re-bias the amps. Let me know if you have any questions PM me I have been repairing CP gear for a long time now.
Happy Listening.
