It's a while since I've been here but I recognize a few names either
from the past or from other places; so first I'll say hi again.

I have enjoyed my Linn LP12 for a few years and in the process have
done some very effective upgrades. First, the Cirkus mod.
Next, it has the Pink Linnk PSU (AC using the standard motor) and also
a new top plate which moves the motor to the front.
Most significantly, it has a Cetech subchassis and I found that this
makes a very substantial improvement (in conjunction with bolting up
the armboard).

I had a Moerch DP-6 arm and Lyra Evolve cartridge on there but these
have been moved to my new tt.
The complete package was really good! Considerably better than a full
spec LP12/Lingo/Ekos/Arkive.

Every time I put another non Linn mod on it, it got a lot better, thank
God :-); but as it's now a long way from standard it might be harder to
sell in spite of its high sound quality.

Any idea how much it's worth as it is, without arm?

Is it a good idea to buy a cheapish arm in order to be able to demo the
deck, and offer a complete package to the buyer? I can't run to an
Ittok for this.

I guess I can replace the Moerch arm for demo purposes but of course
it's a fair bit of effort; I'd do so for a serious enquiry.

Or do I have to do something silly like returning it to base spec and
selling the PSU and Cetech chassis on their own? I say silly as it'd be
the biggest Linn downgrade in history ....
Or do I just stick it on Ebay and hope for the best ....
