[GreenKeys] Frequency Shift Convertor: Boehme 5-C

[David Christ]

Be careful.  The R-388 was a 51J3.  At least all the ones I have owned.  The R-388(A) was the 51J4 as I recall.

The picture with the listing is a 51J3.  This is clear because there is no filter width switch behind the BFO Pitch knob so no mechanical filters.

As you say, the 53J3 is pre mechanical filter.
