No luck finding a BFW0265, the metal case of this bad transistor has the #'s (00734) on it, no luck with that # either.

The May 1974 manual shows TR107 as a type of FET, a Mullard BFW 1052, but that transistor looks to be obsolete also. Besides it's a 3 pin and the BFW0265 is a 4 pin. I hate to toss this scope out over one transistor, it had a new CRT put in about 15 years ago and used very little since. Any idea of something else that may work, (modification of that circuit)? etc. etc?

Thanks.
