Troubles with my Lexicon Reflex
« on: Time Format »

Hey guys,

Anyone with some technical knowledge of the Lexicon Reflex?

Mine started to make small crackling noises from time to time.
The crackling does get a nice reverb tail though, so i gather it starts before the effect processing  :???:

Nothing beats MB-1s and MP-1s with MDRTs

good quality contact cleaner dude(anything not permanently soldered like jacks, switches, pots, connectors, remember those line in/outs as sometimes the signal passes thru until you plug in to one so that internal switch contact must be clean too - be thorough and then it may be a real problem if that doesn't fix...

I had one of these which developed an intermittent rumbling sound, like you would wiggle a jack plug on the input and it made a slight noise that went through the unit, but without actually having to wiggle the jack! Some folks said it was due to the SRAM chips deteriorating, but I changed those and the problem still persisted (I think it used similar/same SRAM chips as the Alesis Quadraverb, which I also had at the time). Anyway, after hours/weeks of probing and prodding I never got to the bottom of it so sold it on as spares. I have the schematics you need them.

Could also be some cracked solderjoints.
