I'm glad to see a positive review. I was disappointed in the unfortunate mistakes made by the Reviewer. I noted:
1. the Model denoted Mk 5, rather than MK 5 in honor of the circuit designer and the series,
2. the switch the back panel identified as a main power switch, rather than as a ground lift switch,
3. the front power switch for an undocumented standby low power mode, rather than for full power shut off,
4. describing a 30 Day home audition before payment, rather than the 30 Day Satisfaction Guarantee.
