50Hz vs. 60Hz

Thanks to all those who have responded on 50Hz vs. 60Hz So to summarise: 1. Most PSUs are unlikely to present a problem, especially since we're going from lower to higher frequency. 2. Tape drives are likely to run just fine. 3. Disk drives will be as expected (pulley issues) for older drives, but RL should work?? 4. The big 'gotcha' appears to be ferroresonant PSUs. I knew those would be a problem, but I must admit I didn't know DEC used them. OK, so we've been told the RX01/02 is ferroresonant. Think carefully folks - are there any other DEC PSUs that use ferroresonant transformers? I'm thinking mostly about logic PSUs from early pdp-8/12/15 to later 11s - 11/34, 11/73, pdp-8a etc, but any data on peripherals which used ferroresonants would also be welcome!
