I adapted Rich's circuit for use in an SB-200 using this winding. It
works splendidly. As I recall the two new relays draw less current
than the original SB-200 relay. I used it for over a year before
acquiring an SB-220. I then loaned the SB-200 to a friend who used it
for two years on CW and SSB with no problems.
