Opinion by
Appellant sets forth numerous allegations of errors, all of which, on the state of the record, we must dismiss as either waived or insufficiently established.
Briefly, Officer Scott of the Philadelphia Police, acting as an undercover agent, approached the appellant who was called “Frog”, and asked him “What’s happening?” The appellant took Scott to his apartment at 2022 Haggert Street, using a key to enter the *505 premises, and sold Mm a packet later identified as heroin. Scott reported the incident to Ms superiors, and provided the police with a physical description of the appellant, his nickname, and the address. He then picked the appellant out of a group of photographs shown to him by the police. Appellant was arrested and charged with illegal possession and sale of narcotic drugs.
A Motion to Suppress was argued before the Honorable Matthew W. Bullock, Jr., Judge of the Common Pleas Court of Philadelphia, at which numerous references were made to the photograph. Appellant thereafter waived his light to a jury trial, and was tried before the same judge, sitting without a jury. Appellant was convicted and sentenced to a term of imprisonment of three to six years. Post-trial motions were orally submitted without argument and denied by the Court.
First, it is argued that the trial court erred in permitting references to be made to the appellant’s photograph at time of trial, and in allowing the Commonwealth to introduce said photograph into evidence. Concomitantly, appellant argues that the trial judge should have transferred the case to another judge after having heard reference to the photographs in the pretrial suppression hearing. It is not disputed that the photograph, as viewed by Officer Scott at police headquarters, was taken from police files, mid therefore, indicative of appellant’s prior contacts with the police in unrelated criminal matters or investigations. In
Commonwealth v. Allen,
Appellant also contends that his waiver of a jury trial was unknowingly and unintelligently made. After informing the Court that he wished to waive a jury trial, defense counsel conducted a colloquy to demonstrate to the trial court that the waiver was voluntary and intelligent. In so doing, he failed to inform the appellant that if he chose to proceed with a jury the members of the jury would have to be unanimous in their verdict in order to convict a defendant in a criminal trial. Our Supreme Court has recently held in
Commonwealth v. Williams,
It must be emphasized, however, that the instant case was tried more than a year before the date of the
Williams
decision. Appellant argues that he should be able to benefit by the decision, and that it should be given full retrospective effect. Both the Pennsylvania and United States Supreme Court have rejected retroactive application of standards for the acceptance of guilty pleas established in
Boykin v. Alabama,
We do not believe that the prophylactic rule in
Williams
to insure that jury waivers are knowing and voluntary should be applied to cases tried before its decision. Jury waivers are common practice in the criminal courts, and to reverse every conviction automatically on the basis of
Williams
would, in our opinion, create the same havoc to the administration of justice as
*508
would have the application of
Boykin, Mapp
and
Griffin
to prior cases. As with the rule stated in
Commonwealth ex rel. West v. Rundle,
Appellant’s final contention that defense counsel’s failure to object to the rulings and procedures involved in the trial of his case, and in counsel’s failure to submit briefs or argue in support of post-trial motions constituted ineffective assistance of counsel, likewise, may not be gleaned from the notes of testimony. These and any other errors not immediately perceptible from the record must be determined in a collateral proceeding.
Judgment of sentence is affirmed.
