I'm hoping that some major digital/analog wizard among us may be able to help out an AKer going through tough times. Can anyone troubleshoot and repair a Lexicon RV-8 or do you know anyone who can? Or does anyone have a connection with Harman, Lexicon or one of their repair centers? If so, please let me know.
Our good friend and tube wizard audiodon has ALS and is no longer able to work on audio gear. We have sold off almost all of his tube projects. Don loves his audio and has a 2004 vintage Lexicon RV-8 AV receiver that was top of the line when it came out. He bought it used about 5 years ago.
The RV-8 quit a couple of months ago. Don checked with someone he knows and found that a Harman/Lexicon service center wanted $500 just to look at it. I said I'd give it a try, thinking it was likely a power supply issue since the unit doesn't come up at all and has only a few front panel lamps on.
All fuses are good and nothing is obviously cooked so I started checking the power supplies. The unit has a Crown-sourced conventional PS to power the 7 Crown 140W amp channels and a triple output switcher to power the logic and I/O modules. The switcher's 5VDC output was only at 3.6V under a test load so I subbed in an external 5V supply, hoping that might do it.
No luck. I believe that this unit has problems on the main logic/control board but I do not have the skills, tools, information or time needed to bring it back to life.
If anyone can help Don out on this, let me know. I have the unit and can get the original box from Don so I can ship it.
Alternately, if anyone would like to buy this as a fixer-upper, please let me know. (Mods, please don't delete this thread for that. I'm trying to help Don. Thanks.)
The AK community has been great to Don and he and I really appreciate that. Many thanks. --Dan
