One suggestion if you do decide to keep the JOR is to drill additional holes in the bottom plate (there are already a bucketful of them) inline with the resistors and potentiometers involved in the biasing procedure.
As the disassembly and (especially) putting the amplifier back together are the most difficult and labor intensive steps, these holes would turn what is one of the most involved biasing procedures in audio into a simple no muss, no fuss 3 - 5 minute affair. Were I Jadis, I would implement it myself, as it would really make life easier for the JOR owners out there.
