I have available some of the original Philips Semiconductor OM345 Wide-Band RF Hybrid Amp IC's new in the box from the 1990's . I know these are invaluable to you Marconi folks in repairing/restoring the Marconi 2955 series Test Sets and 2022 Signal Generators. Have them listed over on Ebay ( Listing #'s 320404125561 & 320404146451 ). Check out my other listings as I also have vintage N.O.S. Amphenol Tube & Power sockets that may be of use to you with vintage electronics. I apologize if this is not the proper forum for posting the availability of these parts but know there are still more than a few of you out there who swear by these old Marconi's and have trouble finding original parts !!! Thank You, DrMcFlip
