Appellant was convicted of possession of marijuana with intent to deliver. 35 P.S. § 780-113(a)(30). He raises five assignments of error.
—:l—
Appellant argues that there was not sufficient evidence to support a finding of intent to deliver, in that there was no testimony as to the amount of marijuana found in his possession. The trial transcript reveals that seven plastic bags of marijuana were introduced into evidence, but there is no description of their size or weight. However, appellant’s motion to suppress averred that the evidence seized from appellant was “seven pounds of marijuana.”
Appellant also argues that quantity of marijuana alone is not sufficient to prove intent to deliver. We held otherwise in
Commonwealth v. Cubler,
—2—
Appellant argues that his waiver of jury trial was not knowing and intelligent because the lower court did not hold an on-the-record colloquy in conformance with Pa.R.
*152
Crim.P. 1101. However, in
Commonwealth
v.
Williams,
Here, after a jury had been selected, defense counsel stated that appellant wished to waive jury trial. Appellant then signed a written waiver form, which read:
AND NOW, Sept. 19, 1974, comes the defendant and pleads not guilty and with the consent of his attorney, and the attorney for the Commonwealth and the approval of the judge, waives a jury trial and elects to be tried by a judge without a jury, fully understanding that if he were tried by a jury:
1. the jury would be chosen from members of the community thereby producing a jury of his peers,
2. that any verdict rendered by a jury must be unanimous and,
3. that he would be permitted to participate in the selection of a jury panel.
From this record we can conclude, first that appellant knew he had a right to a jury trial, because a jury had already been chosen, and second that he “knew the essential ingredients of a jury trial which are necessary to understand the significance of the right he was waiving,”
Commonwealth v. Williams, supra,
—3—
Appellant argues that his suppression motion should have been granted, on three theories. 1
The search that produced the evidence against appellant was made pursuant to a warrant. We reproduce here the relevant portions of the supporting affidavit:
*154 [[Image here]]
First, appellant argues that the warrant does not authorize the search of the suitcase in which the evidence against him was found. We disagree. The narrative recounts that appellant was seen arriving with a suitcase with airline tags on it, and that the investigating officer believed that appellant had marijuana “on his possession.” A common-sense reading of this affidavit is that the issuing authority, finding probable cause for a search of appellant and
*155
his “possession,” authorized a search of the suitcase. The suitcase was “described with particularity in the warrant.”
Commonwealth v. Searles,
Second, appellant argues that the reliability of the informant described in the affidavit was not sufficiently proved by the facts narrated. We disagree. At least two of the factors set forth in
Commonwealth v. Ambers,
Third, appellant argues that the first prong of
Aguilar v. Texas,
The requirement of a determination of the trustworthiness of the source of the information cannot be met solely because it is channeled through an informant known to be reliable. While it may properly be assumed that the informant passed upon the reliability of the third person supplying the information to him, the law makes it most clear that it is not his judgment to make.
Id.,448 Pa. at 263-4 , 293 A.2d at.36.
However, in
Garvin
the reliable informant acted only as a conduit for
all
the information on which the affiant relied for the arrest of Garvin.

Here the reliable informant told the affiant that “he was present when some of the arrangements were made,” and that it was only the “final arrange
*156
ments for the pickup and trip” that came from the second, untested informant. Furthermore, the details recounted by the reliable informant were verified by the affiant’s own surveillance.
See Draper v. United States,
—4—
By stipulation of defense counsel, the testimony from the suppression hearing was incorporated into the trial testimony. Appellant contends that this procedure denied him due process of law and his right to confront witnesses. This argument has no merit: appellant had full opportunity to confront the witness who testified at the suppression hearing and whose testimony was thereafter incorporated into the trial testimony. No doubt appellant’s real complaint, which he vaguely suggests in his brief, is that his counsel was ineffective in failing to ask the suppression judge to refer the bench trial to another judge. However, we cannot find ineffectiveness on this basis alone. As the trial judge notes in his opinion, “there is nothing in the record of this case that was ‘of a sufficient inflammatory nature to arouse a prejudice against the defendant’
[Commonwealth
v.
Goodman,
—5—
Appellant argues that counsel was ineffective in not asking for a different judge because the trial judge had previously presided over appellant’s guilty plea on a drug possession charge. True it is that the prior conviction was inadmissible as proof of guilt on the present charge, but that
*157
the judge probably remembered the plea and thus the prior conviction was in a sense in evidence. However, we find this claim without “arguable merit,”
Commonwealth v. Hubbard,
Affirmed.
Notes
. Two further theories — that part of the affidavit for the search warrant was invalid because not signed by the issuing authority, and that a violation of the “knock-and-announce” rule rendered the seized evidence inadmissible — were not raised in the pretrial motion to suppress and therefore were waived.
Commonwealth v. Jackson,
. It is axiomatic that the standard for testing probable cause is the same for arrests as for searches.
