It looks like a fender deluxe reverb on a stand.
You mean right after the slapping spoons solo? Can't see well enough but it looks Fenderish.
If it's not a deluxe reverb, maybe a vibrolux reverb but I doubt it. It's a fender with six knobs on the vibrato channel and two diagonal rows of words for the name. This takes out the twin and super reverbs (seven knobs) and a dual showman head as the "dual" would be horizontal. It doesn't look like a pro reverb either.
I thought you were joking about the spoon solo. While Myron Floren and his accordion dominate the tune, that electric mando is interesting. It might not even be a Fender amp---control plate looks flat, not angled.
How did you ever come up with this one?
Can barely see the top 3" for 3 seconds or so...But, I believe it to be BF Fender.
Neil LeVang is the Electric Fender Mando Strat player.
Actually one Welk band guitarist was an early Strat adopter, ca. 1955.
...several YouTubes out there.
