LOWTHER

TP1

This photo shows the Lowther TP1 Type A.

The writer (Takuji Yamamoto) replaced the TP1's old PM3 driver with a modern PM3/5.
The gap flux of a PM3 is a powerful 21,000 gauss. However, the PM3/5 is an improved PM3 unit with a gap flux of 23,200 gauss.
I clamped it into the cabinet because the newer driver's bolt holes don't correspond with the old enclosure.
