Just found this awesome thread, I have posted some of my vintage audio on other pinside topics, but here they are again, sorry if they are dups for anyone.
The pioneer fluroscan set-up has been updated since the photo, marantz tuner has been replaced with the matching TX-9800 (took me forever to find a good one )
The Marantz receivers: 2330b, 2285b, 2238b & 2218 are output to a Niles speaker selector switch (wired in reverse) so I can select which receiver to play through the HD880's.
