When you say McShaned on the Jolida,that isn't the term we use on those.That term applies mostly to McIntosh amps,Citations,Eicos,and a few other vintage amps and preamps. The term applies mostly to Macs and Citation amps tho because of their circuitry and build of the power supply.
Now what you can say about the Jolida is an upgrade of McShane chosen parts which will be a definite improvement.
If he keeps blowing fuses,I would look for a bad tube,a leaky diode,or a bad solder connection on the board.Also,look for a bad solder connection on the power supply caps that may be arcing. Can you pull it apart and post a photo of the bottom side of the chassis where the solder traces are? You may have to have Emma remove the board.
