Lexicon MC-1; DC-1 Power supplies
This question is for the Lexicon DC-2 power supply replacements. How has your DC-2 been performing since you replaced the power supply from Mouser at this link from the above threads? http://www.mouser.com/Search/ProductDetail.aspx?R=NFS40-7610Jvirtualkey54020000virtualkey826-NFS40-7... |
It’s a known problem, and a case of basically rape by Lexicon. This is a $45 supply - not hudreds of $$$. It's basically Lexicon telling their user base that they feel that you need to spend more money, and want to coerce you to buy a new unit instead of a trivial repair . . . . I have refitted power supplies in three DC-2’s, and every one ran as well as the day it was built, with no further issues. It’s not like Lexicon used a custom supply - the supply in the DC-1, DC-2, and others is just an off the shelf part (and not a particularly good one at that) and as long as the voltages, amperages, and pinouts match, the number of candidates out there available are multiple. Myself, I have not used the NFS40-7 listed above, but rather the Artsyn LPT-45 https://www.mouser.com/ProductDetail/826-LPT45 As noted, I have done several, the oldest being probably close to 8 years, and never a burp. If it takes you more than 10 minutes to do a supply replacement in one of these, you are doing it wrong! 5 screws for the cover, 4 screws and one nut for the supply, and two connectors, and done! Oh, and bought two of my DC-2’s cheap (last for $29, looks like new) since this is such a common problem, the risk of buying these dead is not very high . . . and, as noted, they still sound great! Finding one with a working remote, however, isn’t as easy . . . |
