Simon,
my reading of the schematic says that once I have pulled Q1352, Q1354, and Q1358 from their sockets the resistors are only connected to the rest of the circuit through two diodes, one of which is reversed biased (assuming that it's not shorted, which is not a given in this case).
If the diode across the collector and base of Q1354 were shorted, however, I would expect that the resistance I read across the two resistors would be less than 15 Ohms, since some other resistance would be in parallel with them. The resistance I'm reading is higher than the marked value of the resistors (and the value indicated in the schematic), not lower.
That said, I really should check the diode CR1354 to make sure it's not also shorted, because, with my luck, it probably is.
(I was originally planning to shelve this project until the replacement transistors arrived, but then I got to thinking about why a couple of transistors might be blown, and started worrying about other components that must have failed in the same event, and realized I could test a bunch of the components if I just removed all the socketed transistors from the circuit, leaving a bunch of disconnected legs. I'm really glad I succumbed to my worry on this, because I'm finding, and learning, all kinds of things along the way)
