The 7904A is an entirely different animal to the 7904. It is pretty rare and of higher performance, and does not have the HT buried in the SMPS. Although formally specced at 500MHz, if you use a 7A29 vertical amp it is close to 800MHz. Whoever you gifted it to, even with a tick of death power supply, is a lucky person indeed.
I've kind of taken a test gear collection a bit to extremes - partly because things I used in the 70's and 80's that were major league investments for the University and companies I worked for are now low in price - and partly because the build standard is such a thing of electronic beauty.
