this problem, and the fact that the shafts of these 2006 to 2009 Resonance pots are too
large (I drilled out the knob’s splined hole) we are very fortunate that Technology
Transplant has gone to the trouble of having these pots manufactured.
In late 2009 and early 2010, there was a new batch of pots from Technology Transplant.
There is still this minor problem with the Resonance pots being “log” on both ends.
However the shafts of all the pots fit the knobs properly, and the pots themselves are a
new design which should last for a very long time. The primary failure mode of the
original ALPS pots was the outer part of the rotor rubbing on the phenolic board, when
the pot was turned and the shaft was pushed down. This would eventually cut through
the conductive tracks. The late 2009, early 2010 batch of pots from Technology
Transplant have a different internal design, so this cannot occur. With luck, these pots
will last a very long time – longer than the original ALPS pots.
The initial set of this 2009 / 2010 batch had shafts which were about 1.6mm too short. I
resolve this problem by mounting them with a laser-cut special spacer. I understand
Technology Transplant is having a new batch made with a different mounting plate, to
achieve the same thing: the body of the pot being about 1.6mm higher than it would
otherwise be.
The Resonance pots of this 2009/2010 batch do not have the noise problem mentioned
below. Before I install these 6 new pots, I dismantle them and replace the stiff friction
grease with thinner silicone grease, so the pots are nice and easy to turn. This grease at
the top centre of the pot, where the shaft enters – nowhere near the conductive tracks and
wipers.
Replacement Resonance pots become noisy
In 2008 I had some trouble with replacement Resonance pots becoming noisy. The
problem is primarily the wipers for the outer section of the pot not making proper contact.
Please see the pot-wear/ page at the Devil Fish web site for more information. I have a
technique for modifying these pots before I install them which so far has fully eliminated,
this problem. This problem doesn’t occur with the pots I used from mid-2010 onwards.
