REPAIRS: Certain unique parts for these things are becoming hard to find.  Replacement DSP & HD Tuner modules are no longer available except by cannibalizing parts from other tuners.  The original Sony RMT-CF1A remote control is also now NLA as a separate part.  Since remotes are often lost, in the near future I'll have to substitute a universal remote, or just not include a remote at all.

Regardless, if you have an XDR-F1HD  that doesn't work, contact me.  I can probably repair it, sometimes at very minimal expense (depending on what's wrong).  On repairs I generally don't charge anything for my time.


​​EBAY: Current ebay listing: None, but see the For Sale link!

Mods are priced individually as shown, add $15 for return shipping.  Or $275 for Items 1 thru 10 when done all at the same time, including return Priority shipping to a US address.  

  1. ​Install two premium-quality expensive ULTRA QUIET internal cooling fans.  $60  **This mod is so important it's mandatory.  Based on years of experience and hundreds of these done, I can't warranty any of the other work if the fans are omitted.  So I have to decline any work that doesn't include adding fans. **
  2. Disable the tuner's analog audio preamp & replace it with a custom 4-layer analog audio preamp board.  $100
    • ​​The new audio board is silkscreened & soldermasked, and uses through-hole parts.  Nothing is surface-mount, no sockets, jacks, or connectors.
    • Each audio board is hand-assembled using silver-bearing solder 
    • Audio performance specs for each board verified with an HP Audio Analyzer.  This includes frequency response, distortion, S/N ratio, and headroom.
  3. Install Forced Analog switch including LED indicator for FA Mode (requires drilling hole in rear panel).  $20
  4. Install auto-shutoff for the display backlight when the tuner is in Standby.  $20
  5. Upgrade the original zinc-plated audio output jacks with gold-plated premium panel-mount jacks. $25
  6. Install "super capacitor" memory backup to preserve station presets & time during loss of power. $20
  7. Replace all the top & front tactile pushbutton switches. $10
  8. Align the FM section for best sensitivity. $20
  9. Replace all of the main board 85℃-rated aluminum electrolytic capacitors with more robust long-life 105℃ parts, voltage derated where feasible.  Now also includes replacement of the aluminum electrolytic capacitors in the main tuner module with higher-quality parts. $50
  10. Power Supply: Upgrade the smoothing capacitors with more robust parts, reduces power supply ripple.  Upgrade the 10.5V side of the power supply from half-wave rectified to full-wave, improves efficiency & reduces ripple. $35


  • Remove the factory power supply and replace it with a universal external power supply that runs on 100-240VAC 50/60 Hz.  This eliminates a major source of heat inside the case.  Delete #10 above, add $60 (total for items 1 thru 9, with external power supply, is $300).

Note about the tactile pushbutton switches: I've been running into increasing problems with flakey pushbuttons.  For example you press "DISPLAY" but the tuner behaves like you pressed "HD SCAN".  This is caused by the tactile switches developing high resistance across the contacts.  I can now replace the switches with new exact replacements for $10.  If you want to DIY the switches are Mouser p/n 611-PTS645SSM502.  Note that the original switches may have felt pads on top that you will probably need to transfer over to the new switches in the same locations.  Otherwise when the cover is installed the buttons may feel mushy or not work without pressing very hard.  If you're going to replace any switches at all, consider doing all of them at the same time including the power button.
