[TenTec] 238 Manual Addendum (extra cap)

[Bill Acito <w1pa@hotmail.com>]

If you add the extra cap to the back of the 238 tuner, it is added to position 
3, 4, and 5 ---  not just 5. I found this out while doing a repair. The 
schematic seems to indicate this, but the verbiage in the manual implies it is 
only added to position 5.

I don’t know if this true of later versions (e.g. 238A), but I confirmed it on 
two original 238’s.
This means if you decide to just leave the cap there under normal usage, you 
are missing a large chunk of capacitor range between the end of 1-2, and 3-5 
plus the cap.
