That reminds me of my FADA model 1001, the previous "repairman" took an aluminum twist lock can that barely fit under the chassis, and stuffed it inside a tube box so it wouldn't short anything out. Another common butcher repair I have seen was to cut an aluminum electrolytic can in half and then fasten the replacement inside by peening over the edge of the can to pinch it in place, one example I saw was done by a repair shop. Duck tape to hold a cap in place doesn't surprise me, I repaired a Canadian Philco model 84 from 1949-50 where the previous repairman didn't have enough room for his second electrolytic under the chassis so he fastened a 30 uf 450 axial lead cap to the back of the speaker with a twist tie, string, and electrical tape.
By far the worst butchery I've seen comes from sets that were worked on by HAM operators. Most HAMs are alright but some think their license also means they have a degree in electronic engineering that qualifies them them to second guess the engineering labs at Philco or RCA.
