The Marantz PM4 is another great amp of the era. A bit thin on the ground, but worth looking out for, if you have reasonably efficient loudspeakers.
Also PM-94 ( think I've elready said that. )

no fair jhmee9. play nice please
Yes, jhmee, you know how us Onixophiles covet that set-up. Grrrr. I though you'd sold it all, anyway?
Sean, no speakers connected, black probe into black speaker output connector, red into red. 50mV or less, though up to 100mV acceptable I believe.
That's not the output stage bias though.
there's a MC750 on the bay at the mo.[/IMG]
This MC2 650 is a 90s amp awesome when used as an integrated.
I still own and use an Aura Evolution VA-100 MkII in my second system.
The company was owned by B+W I think.
Not as detailed or punchy as my Naim stuff but still a very easy listen.
i have recently bought an old Incatech claymore, i have only had a few days with and it was to be a stand in until a can afford a new amp to go with my new speakers, but have to say i am pretty impressed with it...i am not sure what i would gain by spending 5 or 600 quid on a more modern integrated. i also had the pleasure of trying a Nait 2 not so long ago, as well as an ION obelisk 2 and also hearing an Onix 21 at a friends. All have been great and impressed me. I was also interested in the John Shearne Phase 2 but have not as yet heard one. These are all sort of 300 - 500 quid integrateds from that era
Hi if you need circuits please ask, also DC offset test should be about 10mV volume down no load, the bias current we set by this method it worked very well.
You will need a signal gen set to 10KHz at 1VRMS
A large say 25W 8ohm load not a speaker.
A fine screw driver.
And a scope.
Inject the 10HKz signal it the CD with it set to CD volume down.
Load the test channel on to the correct channel.
Connect the scope probe Blk/sheild to the BLACK terminal of the Claymore.
And the TIP to the RED please doesn’t get it wrong.
Set scope to 1V/CM and 100uS, adjust beam to centre screen
Now adjust volume to produce 1Vrms on the load.
Now adjust preset see cct diagrams to produce cross over distortion on the displayed sine wave,
Now adjust the preset so the clipping is gone.
Now that should be the best setting to run cool and sound good.
Now the Main Bulk caps by now will be past there best replace them.
Make sure the MOSFET are still up tight to the heat sink bracket and it is clamed down tight to the chassis before you do anything any problem please tell me.

How would you use one as an integrated?
Ah, makes lots more sense. Actually I would use my mixer as the pre (which currently pres the pre in my integrated amp) which does have balanced XLRs out. Thanks.The Inputs are
balanced.
You would need a
DI Box, this direct
injection box will
allow you to use
a pre-amp!
You could use a
mIxer but it would
have to have the
balanced Line Out
option.
Hope this helps?
