I'm 95% sure it has to be CLV. Most of the parts used in the Emax 
were parts readily available for the Mac since it was the most mass 
produced computer at the time. I've been telling people to get a Mac 
classic compatible drives for 5 years now and no one has corrected 
me. Isn't the information in my FAQ?

It would be great to order parts from E-mu, but let's be honest they 
charge too much for most parts.

pasted below is a fellow users email about replacing the power supply 
himself. Remember do so at your own risk!!

Basically, it goes like this:  

Go to a computer parts/supply store & buy the cheapest power supply 
you can find.  I paid $14.99.  Also pick up some heat-shrink tubing.  
You will need a wire stripper, soldering iron & solder & screwdrivers.  
Open the Emax from the bottom & then locate the power supply.  Find 
the cables that run from the power supply to the motherboard (3 sets of 
purple, green, orange, yellow with red plastic connectors at each end) 
& write down which voltage corresponds to which color.  This is printed 
on the existing power supply's circuit board.  Note also the 2 red wires 
that go to the 120/240 switch, ground & the brown/blue pair which 
come from the on/off button. Disassemble the power supply you 
bought & write down which voltage corresponds to which color.  Save 
the fan & leave it's cables attached. Remove the old  power supply 
board & mount the new power supply board.  Be creative.  My Emax 
doesn't have the hard drive, & the power supply board I bought had 2 
holes which lined up with the hard drive mounting studs. Also, I was 
able to mount the fan that came with it to the side of the floppy disk 
chassis.  You may have to build a bracket, etc depending on the power 
supply board you purchased & the configuration of your Emax.  If you 
don't want to use the fan from the new unit, I assume you can ditch it 
since the Emax didn't have one in the first place.   Then, you basically 
solder the brown & blue wires that went into the old power supply 
board (from the on/off switch) to the (probably) black & white wires of 
the new power supply board, wire in the ground, connect the 2 red 
wires that go to the 120/240 switch to the wires that do that same on 
the new power supply board & hook the 5 & 12 volt cables to the 
corresponding Emax cables.  To prepare these for soldering, you snip 
those cables at the plug that used to connect to the old power supply 
board (leave the red plastic connector on the Emax system board...you 
strip the wires at the other end of this connector...again, where it 
plugged into the old power supply board) & cover all your solder joints 
w/ heat shrink tubing.  We took these & twisted together the 3 purples, 
3 greens, etc & soldered them to a single wire of the corresponding 
voltage from the new power supply board.   Snip the extra cables from 
the new power supply board & wrap it all with electrial tape. Put the 
cover back & fire it up!  

If you have a crude understanding of electronics, this should 
be a breeze.
If not, find someone who does as it will be simple for them.  
The idea is
that if this happens to you, it can be fixed with readily 
available parts.
I realize this isn't an exact "how to", but covers the general 
facts & YES
it does work.  This should point you in the general direction 
& the pieces
will fall into place once you have everything in front of you (& 
you have
some basic electronic knowledge).  Emu want's $95 for the 
power supply &J
long story short, I couldn't ever get them to process the 
order.  So, for
$15 you can do it yourself, or use the $80 you save to pay 
someone to do
it :)  That's pleny of beer to bribe your electronic-savvy 
buddy.
