The components associated with the XTAL oscillator (V5 pins 1, 8, and 9 - R220, R225, crystal Y202, 8-
50pf trimmer cap, C210, C221, C222, L202) are not present and there is no provision for an external
LMO/VFO.
R205, the 2
nd
RX Mixer (V12) screen resistor is 100k (vs 330k on SB-102)
R223, the 2
nd
RX Mixer (V12) Cathode resistor is 1k (vs 330 ohms on SB-102)
R210, the Heterodyne oscillator (V19a) grid resistor is 10k vs 4.7 k on the SB series
