Philco 77 hacked?
#1

    Thanks for adding me to the group. I've learned from numerous threads here, and wonder if anyone can tell me if I'm seeing what I think I'm seeing on this chassis. The power transformer has 12 terminal lugs and they are arranged (with the chassis's controls pointed to the ceiling) 1-4, 5-8, and 9-12 corresponding to the labeling on the schematic. On this chassis, the last four lugs have no wires attached so the leads that provide power to the rectifier are not connected to the power supply. Instead, a Philco part 32-7180n listed on Playthings of the Past as a power transformer is bolted to the chassis between the choke (a 3422) and the first by-pass condenser. In addition, some past technician placed a pair of 8uf electrolytics on the lugs for the filter capacitors. I should also mention that lugs 9-12 on the power transformer show open on my DMM. I can not find a part 32-7180n on the schematic, so I'm guessing the guy who tied electrolytics across the lugs of shorted capacitors tried to power the "D" and "E" lines separately? The thing is, except for all the electrician's tape on the leads coming out of the 32-7180n, the mounting looks original.
The schematic is at http://www.philcoradio.com/tech/images/77.jpg

Thanks for the wisdom in advance.
