View Full Version : A real long shot Need OM 345 or OM 2045

Yes, I know it's a real long shot, but I need several Phillips OM-345 or Phillips OM-2045. These are Wideband Amplifiers in an 5 pin inline hybrid integrated package. I need them to repair my Marconi 2955 Service Monitor. There is little hope anyone would have any, although there were also used in some signal generators, and external TV RF amplifiers. There is a possibility that I can build an outboard replacement, but it would greatly affect the flat response from DC to 1 GHz.

Any ideas or help would be appreciated.

Yeah, I saw them. But they are higher than giraffe nuts, and I need four of them right now, and would like a few spares. I have a data sheet that shows what they are comprised of, and the values that someone else posted. There isn't but a hand full of components, so I'm considering building some up on a small pc.

I also see a place in California has two complete units, supposedly working, for around $400 each with free overnight shipping. Since they normally go for a couple of grand and up, the red flags are waving. In the mean time, I have the IFR I can use, but I like the Marconi is a little easier to work with.

You gotta sweet talk 'em down! Put on an animal print tan and brown spotted dress, a little lipstick and perfume and those babies should fall right into your lap!

Have you tried Mouser? If they don't have it, you're pretty well screwed.

They have been out of production for a loooong time. Chances of finding any at a decent price are slim to no effin way.

If they have them I can run up and get them and send them to you. They are in Huntsville AL, they have all kinds of stuff. Old and really old. They have been there for 45++ years. That just might talk you out of sending the BOX-O-RATTLESNAKES to me.

So, did you call them, or were you too busy mashing the button on the worlds most important gadget? There's physics, audio technology, electrical circuitry, and fossil fuels used in what you have. I don't see Adam whining (or being Carl, just to be PC), all he got was something that consumes energy, you can't take it to the movies,and is a burden to his family. You got something that makes people laugh, while all ham radio exudes is a WTF moment.
