I have for sale an excellent condition Sony XDR-F1HD HD Tuner that has been realigned and upgraded by Ebay tuner guru XDRGUY. The tuner comes with an AM antenna, an FM antenna, and remote.Some of XDRGUY's upgrades: "To improve the audio performance I install a new custom audio board that completely bypasses the XDR's original analog audio preamp. The audio board uses the ultra-premium high-bandwidth Linear Technology LT1632 opamp & Nichicon audio-grade coupling capacitors." "The circuit board is Made in USA premium 4-layer design, hand-assembled by me with quality components sourced from reliable suppliers like Mouser and Digi-Key without regard to cost! Dedicated power & ground layers
Silkscreened & solder masked
All components in the audio path are hand-selected for matching Left & Right performance
Silver-bearing solder is used on all connections
No jacks or sockets
Only through-hole components used, no surface-mount parts" "These tuners run hot. Long-term exposure to heat kills electronics. I install 2 ultra-premium quiet cooling fans. Measurements confirm a 20℃ reduction in the XDR's internal operating temperature with fans installed. The fans automatically shut off when the tuner is off. The fans are critical to extending the tuner's service life and probably the most important upgrade." "The tuner easily loses the station presets (20 FM + 20 AM) and clock time. More than a few seconds without power and all your presets are gone! To fix this I install a Panasonic 1.5 Farad “Super Capacitor” that retains the station presets & clock time for hours when power is lost." "The tuner's LCD display backlighting is always on: If the tuner is plugged in, the display is lit up! I modify the backlighting so it shuts off when the tuner is Off. When the tuner is On, the backlight works as usual, including the High-Medium-Low brightness settings." "The tuner's power supply has been substantially beefed-up:
The old standard-life electrolytic capacitors have been replaced with Nichicon Extended Life HE & PM Series capacitors. The new caps are double the values of the originals, reducing DC ripple by 50%.
The +10.5V side of the power supply has been converted from half-wave rectified to full-wave, further reducing ripple and improving efficiency.
The wiring from the power supply to the main board has been upgraded from 24 AWG to heavier 20 AWG." "Sony used cheap zinc-plated audio jacks: I replace them with premium gold panel-mount jacks." "Forced Analog option switch added to rear panel. You can listen to digital HD1 programs in analog if you want." The tuner also has the highly desirable external power supply option. I'm asking $395 or best offer, free shipping at my asking price. I accept PayPal but the buyer is responsible for paying their fees. I also accept USPS money orders. I will only ship within the USA. I have excellent feedback on Ebay as Gelajoy (1000+ rating at 100%.)
