[HAM] 122 doesn't want to change to slow

[mtcasino]

The Caribbian installs the exact same way; you plug it in and mount it to
the Leslie.

The Hamptones are not troublesome per say. You definitely have to have clean
lubricated motors. Not so much so with the Caribbian thou it don't hurt. The
Caribbian delivers more turning power than the Hamptone.

I have always heard from the one who is selling a product that it is the
best and there is no problems. A number of techs use the Hamptone. But a
larger number of techs are using the Caribbian. Check with the MITA people.

What I don't care for in the Hamptone the most is the lack of isolation from
the AC Mains to the circuit. The same type of circuit is used in cheep cell
phone power supplies. That may be OK if you're only drawing 20ma or so of
current, but not for this item. Let me spell it out. Half the AC Main is
connected directly to a diode and a dropping resistor; this is your B+. The
other leg of the AC Main goes to a fuse then to circuit ground!!!!

The second thing that bothers me is the use of a M.O.V. (metal oxide
varistor) at the AC output. These little beauties suck up any spikes caused
by turning on and off the motors. Great idea on paper. But M.O.V.'s can only
do this for a period of time and then they do nothing. It is like having a
whole pie and removing slices of the pie until there is nothing left. So
when the M.O.V. is useless those spikes will play havoc with the CMOS chips
in the circuit. 

The third thing I don't like is The Hamptone has 4 switches with 4 possible
speed selections while the Caribbian has 4 switches with 16 possible
selections. This is kind of a mute point because only 1 or 2 settings will
be right for your ears.

The last thing is, and this goes for both controllers, they both use those
dam soldered in micro fuses that are the size of, and look like, resistors!
I never had one go on me in either controller but it just bugs me.

I'm not completely sure if the EIS SSR needs a load on it in order to switch
a motor controller or not, but the Caribbian dose provide a circuit to
accommodate SSR's that do not.

I'm still considering going with the motor controllers though. Are the
Hamptone controllers troublesome or something? I was told by someone (a pro
tech) that he uses them, and hasn't had any trouble with them, and that they
work good. Also they are pretty much plug and play. Isn't the Carribean
Controls controller a little more work to put in?
One question I have on the motor controller subject; My 122 has the SS relay
in it. Will it make any difference in the installation of either of the
motor controllers?
