The meter as used in the 238 tuner is a 200 micoramp meter. There is no
shunt.
I suggest you check with Paul at Tentec Service to obtain a replacement.
Plus, it wil have the correct scale.
Being one that does troubleshoot and repair equipment myself, I do not
replace parts unless I can confirm they are defective. Many times replacing
a part may introduce other issues. In my practice, experience and thinking,
the shotgun repair technique is not suggested.

I think the meter in the 229 is 200 microamps not 200 milliamps listed the
Futurlec meter.
Not sure what the basic movement is without the shunt.
