Ticket holders who tuned in the broadcast on WNUV-TV, Channel 54, of last night's Maryland Lottery drawing found themselves tuned out just as the numbers were being announced.

A power outage knocked out the station's transmitter in Catonsville seconds before the live drawing, said lottery spokesman J. C. Shay, prompting a flood of calls to lottery headquarters.

A tape of the 7:58 p.m. drawing was to have been played every half hour for the rest of the evening as soon as the transmitter was back on the air, then hourly through the early morning.
