we've had an epidemic of failing Tenma dc supplies that fail to maximum voltage (shorted pass transistor), and have blown out expensive stuff in some research labs here fwiw, they are models 72-6905 and 72-6615; they are (i think) linear supplies maybe best to avoid these things altogether -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu" group.
