A BF Deluxe is a great amp. The stock Oxford speaker (12K5?) has a very sweet voice. It's not a loud speaker, and it falls apart on the low end. But find its sweet spot, and you're in heaven.
It looks like your particular amp has a (massive) replacement output transformer. I wonder what the story on that is.
no brainer to get this deluxe instead of a DRRI
The red square is the location of the mains voltage selector for amps fitted with an export power transformer.Also, what's that red square where the AC power receptacle should be?
These non-reverb BF Fenders are great sounding amps. I wouldn't trade it for a reissue Deluxe Reverb. I would put new tubes, a better speaker and if needed new caps. Nothing beat's these old amps. You can always add reverb via out-board tank, which I prefer anyway. I bought mine, in mint condition, for $ 1100.
