The 'Operating Instructions' (user manual) which I downloaded from HifiEngine state (section 1.11, page 11 of that .pdf file) :

'The reverse function is performed only at the end of the tape transport to the right. If continuous reversal is desired, please consult your dealer'

So that's why I assumed there was an official modification, at least planned.

And yes, continuous auto-reverse could be a right pain in record mode, and I guess that's why it wasn't the default. Pity they didn't have a 3 position 'reverse' switch (stop at tape end, reverse one, reverse continually), but I can't believe the modification involved changing all that.

You could, of course use an endless tape spool (the machine is documented as supporting those) if you can find one.

I am, of course happy to chat about this machine and any faults I find/cures. At the moment I am just looking over it and then will partially dismantle the mechanical side (nothing that will upset the head alignment!) to clean off the Evil Goo from the old belts...
