Sony TC-5550-2

Sony APR-2003

1 9 7 4 november 1974
1 9 8 6 1986

One of Sony's little remembered but excellent open-reel, sold in Japan under the TC-5550-2 moniker, for the princely sum of 178,000¥.
It also is one of the cutest chunk of audio kit ever designed.

Good enough, too, to see a (clearly) professional version under the APR-2003 badge, adding black looks, better speed stability through Quartz Lock, XLR plugs, a center track for sync'ing and related XLR i/o, a low-cut (high pass) switch replacing the line/mic selector, and no pitch control function.

By the time the APR-2003 replaced the TC-510-2, the famed TC-D5 portable pro cassette recorder was about to replace just about everything everywhere, before its subsequent TC-D5PRO and TC-D5PROII versions would be somewhat undercut by the WM-6DC pro recording... Walkman.

However, the TC-5550-2 remained available in Japan until 1986, two years after the venerable TC-777 !
This means that, beyond its pretty-pretty face (diecast aluminium, mind you), it must have had something special, sound-wise and reliability-wise.

Nudies aplenty here
