I just bought a Melos tube preamp that I have to pay for, so selling my recently serviced Onkyos. The M-504 has the green LED mod (no more changing lamps ever) and needed nothing else - it works fine. The wood side panels were veneered in dark wood. Looking for $550 for this unit.
The P-304 preamp also has side panels were veneered in dark wood and the 4 op amps were upgraded to quieter LME49860 low noise OAs. Sounds great. Looking for $240 for this one.
Thanks for looking - PM me if interested.
