Hello,
There are actually two Filtech units inside the
Mk. VI. One unit appears to be located on
(I assume) the "IF board". Another, different,
unit is attached to the "RF assembly".
This "RF assembly" is interesting. It is fully encased,
and bolted to the main U-shaped board. The tuning "wheel"
attached to the tuning capacitor is a machined wheel
with a grove for the drive belt. This attention
to detail is quite remarkable. Usually this "wheel"
is either plastic or stamped from thin metal. The stamped
ones seem to, invariably, get warped or bent with time
from the pull of the tuning cord.
The construction inside still amazes. This kind of build
quality just isn't seen inside consumer equipment. All of the
boards are nicely layed out. Nicely finished, anodized
aluminum is used throughout, soldering work is excellent.
The resistors are 5%. Really nice.
Once the chassis had been dusted off, it looked like new.
Does anyone else in the group have experience with the
Mk VI, MK I, or MK III they would like to share?
James,
I guess I'll leave the intensity control alone. It does
seem to work OK. I just hope the repair person used the
exact, specified value.
Best regards,
Paul Bigelow
