I've got a Stella "Stellaphone ST454" four-track reel-to-reel (electron tube
based.. warms the room in winter :) here - the connector I've got for the
inputs looks like this:

  O | O
.. as in, two round pins, with a vertical pin in the middle. It's labelled
"R" on the connector panel ("Record Player or Radio Input"). There are also
two connectors that consist of three round pins - two large ones on the
outside, and a small one in the middle. They appear to be used for the
speaker and headphone outputs. The microphone input is a 3-pin DIN.

The ST454 needs some restoration - there's a brown stain in the inside of the
top plastic (polystyrene, according to the destructions) cover (from the
tape?) and the cabinet covering is peeling away. It is, however, fully
functional (electronically speaking). Valve complement is - EF86, ECC83,
ECL82, EM84, EZ80.

If anyone's got a set of schematics for the ST454 (or knows which Philips
recorder it's equivalent to), please let me know!
