Looking for a pair of DEC RL02 drives, working or otherwise

That is a good idea. A DPDT switch could flip to RL01 and engage the 
write protect switch since I forget to do that. A lot.

Same here. I ran a pdp11/03 at home in college and upgraded from RX01's 
to an RL01. The speed was amazing and when I got a second one and an 
11/23+ cpu I could run RSX11M and Decnet to connect to the school's 
network.

Still they are a bit tempremental: My current pair of drives give a 
different count of errors even though I have tuned the amps to proper 
values on both of them. Bringing the value up more makes the errors go 
down, maybe I should just crank em up.

But that will probably screw up writes. Hm.
