Easier to accommodate than a l300. Seems a good price for a relatively new unit.

Interesting, seems to be early enough it was before the lifetime warranty also, so can’t be sent back for correcting things like the volume etc.
Looks very cool, but twelve large… No chance!

That’s somewhat moody. Look at the cable adaptation (Should also be bound & sealed in plastic - The headshell has screws in it (Bit of a tell tale with the shure cart leaflet - it’s probably mounted) All of the screws should be in sealed plastic - The box has had a tough paper round. All together a well used arm bunged back in the box

Question is, what do the front switch and rear switch do.
Front appears to be connected to what looks like two AA batteries 
Rear is off of the mains in.
I reckon the front switch is the input sensitivity high low
rear is likely mains ON OFF
Battery - No idea

Yeah from tracing, rear is definitely power switch only. The front switch though I am wondering if it switches from triode to pentode mode
I’m quite sure that it’s not that. its a gain setting
Battery bias? think @sjs has used it a few times so may be able to identify what it is

@Valvebloke might have an idea.
I pondered that but it is only one holder and you would need one per channel, surely?
Difficult to work out from the photos, but it appears that the two cathodes of the input valve are connected to the switch via resistors, and via the batteries (orange wires), with the centre of the switch to ground? (purple wire).
The switch then changes the cathode bias between either the batteries, or the 2 resistors. The batteries would need to be re-chargeable types, with the cathode current similar to the trickle charge required by the batteries.
Unusual, but not totally unknown.
