In the lower left hand corner of the picture of the underside of the chassis, there are two, blue electrolytic caps, the replacement bridge rectifier and supporting carbon film resistors(the tan ones) which is what your tech replaced. What you need to replace are the high voltage electrolytic caps. Those are the ones which will include both 200uf/250WV sections. Again, follow the two red twisted pair leads coming from the power transformer. One red lead will connect to the junction of two diodes. The diodes are new. They have been replaced by your tech. The other red lead will go to the junction of two 200uf/250WV caps. Specifically, the connection is to the body of the paper covered electrolytic cap. It is original. It is worn out. It needs to be replaced. Also, from the body of that worn out cap will be a wire connected to the positive terminal of another electrolytic cap. It will have two sections. One of those sections will also be 200uf/250WV. The other section is probably not worn out. It does not matter. It will have to be replaced anyhow. Finding that second multisection cap will likely be very difficult. You could try at Antique Electronics in Tempe,AZ or at Triode electronics in Chicago. They may be able to help you. If not, you can also use generic high voltage electrolytics under the chassis to do exactly the same job as the original caps. It's not a hard job. Perhaps your tech could do it for you. That's all that's wrong with your receiver. Replace those two caps and you'll be back in business again.
