I applied two thicknesses of speaker gasket material to the top of the power transformer.

The speaker gasket material looks very much like the dense foam Fisher used not only on top of the IF board, but also on either side of the glass dial scale and on the inside edges of the front panel.
After I put the foam on top of the transformer, I put the top cover back in place - no more thump.
The foam on either side of the dial was long gone, so I applied more speaker gasket material to those areas, as well as either side of the inner surface of the front panel.

I pulled the off-on-volume control from my 220-T junk chassis and it seemed to be in perfect shape; both sections of the switch work properly!
A word of explanation here: Most of these mid to late 1960s Fishers use a DPDT power switch. One side controls the receiver itself; the other set of contacts controls the outlets on the back of the receiver.
The switch I had put into this receiver from a junk 175-T chassis only had one set of working contacts.
So I cleaned the dual pot with DeoxIT and into the 700 it went. I set the other control aside for a future attempt at cleaning the switch.
Then I put the covers and front panel back on the unit. The 220-T junk chassis had a set of good feet; these were transplanted onto the 700-T since I will not be using the cabinet. You'll see why I am not using the cabinet shortly.
I then hooked up a set of speakers, and tried it out...

The right channel is louder than the left. I did notice as I was testing the transistors on the control amp board, that one of the transistors had somewhat lower gain than the other three - this may be the reason why. Other than that, the receiver sounds very good.
The final thing to do was to put it into my Mid Century component credenza. This is why I could not use the cabinet - there is not enough room for the receiver's cabinet with the unit in the credenza.

Here it is - a nice Mid Century stereo setup in the living room. The component cabinet was sold by Radio Shack between 1961 and 1966. The speakers are Wharfedale W-60s, made in the early to mid 1960s. The receiver is a 1967 model. Now I can choose between this unit and my Motorola hi-fi, also in the living room.
I know a lot of you don't care for the flat screen TV, but we felt that we needed to make some concessions to contemporary life. The TV sound will play through The Fisher and the Wharfedales.
So now as I type this, I am allowing the 700 to "burn in" and it is playing nicely. I have it connected to my attic antenna, which is also used for TV. That is my next home project - to get the antenna off the attic floor and mount it permanently to a pole in the attic, the same way I had the antenna mounted in the attic of my previous house in Evansville. We almost never watch TV, but it is nice to be able to see the news and weather occasionally.
That is it for the 700-T; as far as I am concerned, it is all done.
