Common Problems
 
  
C30 and C32 (100 uF, 25V) have a tendency to leak or short, causing associated resistors R30 and R32 (240, .25W, 5%) to overheat and fail.

Two 5CT1N units purchased online had this fault, and replacement of the capacitors and resistors restored proper operation.

Common Problems

C30 and C32 (100 μF, 25 V) are under-rated and therefore have a tendency to leak or short, causing associated resistors R30 and R32 (240 Ω, 0.25W, 5%) to overheat and fail. C30 and C32 should be replaced with modern equivalents rated above 35 V.
