    This model might have been equipped with a different number of transistors depending on date of build. ERT 1725 Service Chart (dated Dec. 4 1969) lists 24 transistors and 10 diodes, while we can find only 23 transistors on the ERT and on the original schematic, plus 2 for a phono preamplifier board only shown on the ERT schematic.

    IF frequencies vary as well: ERT shows 468 kHz for AM while the original documentation mentions 444 kHz. There might also be a version for continental Europe with an IF of 450 kHz.
