Arran Wrote:The 25 cycle sets usually had larger value filter capacitors and possibly a larger filter choke but the rest of the parts were the same.
Except for the power transformer. A transformer designed for 60 cycle operation will burn up at 25 cycles. However, a transformer designed for 25 cycles runs fine on 60 cycles.
