R24 (5K1) and R15 (820R) are mounted on a curious triangular tag board at the back.
Two 10K resistors have been paralleled to achieve something close to 5K1
R24 and R15
R26 and R29
R26 (560R) and R29 (150R) are mounted on the band-change wafers.
These seven resistors are the only small carbon composite resistors that should require
